Semaphore has introduced the S20 SHDSL modem, which
provides dual Ethernet transmission at high speeds over cop-
per wire pairs. The modem enables conversion
of an existing copper wire infrastructure into a
high-speed Ethernet network when installing a
new SCADA or telemetry system, even if it
spans distances previously unattainable by con-
ventional DSL technology
The Semaphore S20 SHDSL modem extends
communication speed and reach without the
additional investment of installing new commu-
nications media. An alternative to wireless
technology, the S20 SHDSL's unique repeater
capability enables communications over exist-
ing copper wire networks spanning up to hun-
dreds of kilometers. The modem is well suited
for railway, pipeline, utility and power trans-
mission applications that presently employ cop-
per wire communications networks.
The S20 uses G.SHDSL (Symmetric High-bit rate Digital
Subscriber Loop) technology for sending and receiving high-
speed symmetrical data streams over a single pair
of copper wires at rates between 192 kbps to 2.31
mbps. Also known as G.991.2, G.SHDSL is an
international standard for symmetric DSL devel-
oped by the ITU.
Semaphore's implementation is a rugged
design that is suitable for industrial applica-
tions, which require operation over a wide tem-
perature range. The S20 provides transparent
Ethernet connectivity and supports any stan-
dard, IP messaging such as Modbus TCP.
Symmetric communication also allows video
and voice transmission.
Configuration of the S20 is extremely simple
and uses a web interface to display DSL and
Ethernet port status and configure line speeds,
network address, and authentication permissions.

When Failure is not an Option When Failure is not an Option Enhancing the Reliability of Environmental
Monitoring Systems
What good is an environmental
monitoring system that cannot be relied
on for continuous, 24/7 supervision?
Choosing a monitoring system is
important, and considering the
demand for such systems is based
on security they provide, it is pointless
to investtime and money into something
that is not completely reliable. In this
exclusive Remote Magazine article,
CIMTechniques explores this subject and more.

Next Generation Corrosion DataManagement Tool Released
Corr MD, a data management and integration tool is
being released by DNV CCT, in cooperation with DCG,
Inc. The Corr MD
is designed to
prevent corrosion
and increase the
availability of
pipeline data,
this maintaining
vital information
regarding the
integrity of both
onshore and offshore
pipeline systems.
One of the driving forces behind the development of
Corr MD was a study conducted by DNV CCT and
NACE International on the enormous cost of corrosion in
the US. The study estimated that corrosion is costing
pipeline operators approximately $7 billion per year.
Acknowledging this reality, the pipeline industry has
long been asking for an integrated decision tool that can
manage corrosion data and data for integrity assessments.
With the release of Corr MD, DNV CCT and DCG
aim to take the first step towards achieving a complete
set of integrated decision tools needed to manage
pipeline integrity threats. Operators need to know what
information to collect in order to ensure that corrosion
activities, such as monitoring and mitigation, are man-
aged properly. Corr MD provides both guidance for col-
lecting the data and directions for proper usage and data
management. Unlike current risk-management and cor-
rosion assessment tools, Corr MD manages information
from a multitude of corrosion monitoring and test
results, such as gas analysis, coupon monitoring, liquid
composition, residues, inhibitor and biocide use and
operational conditions, etc.
Corr MD software can be customized based on client
input to ensure that the exact needs are met. The tool
includes interactive, logic-driven data entry forms and
can be used both as a stand-alone application and with
network-wide usage, providing centralized data man-
agement with multi-user access. User-defined reporting
parameters, data assessment, record retention and auto-
mated task scheduling support the requirements and
assist in compliance with 49 CFR 192 and 49 CFR 195
in the US and CSA Z662 in Canada. The tool also offers
tiered security levels and image-storing capacity and is
compliant with Pipeline Open Data Standard (PODS),
Orbit+Pipeline and other industry-recognized risk and
integrity management systems.
The first release of the program focuses on internal
corrosion management, but subsequent releases will tar-
get key integrity tools required for corrosion manage-
ment, activity planning and budgeting.
Control Microsystems Releases itsSCADAPack 350E andSCADAPack 357E Controllers
Control Microsystems has introduced its
SCADAPack 350E and SCADAPack 357E, two addi-
tions to the SCADAPack
E-series family. These
products respond to the
growing demand for
interoperability and reli-
able communications by
featuring native DNP3
and IEC 60870-5 and
multi-vendor connectivi-
ty. AGA12-2 encryption
ensures data integrity for
billable applications or critical operations. Both prod-
ucts share the same hardware platform as Control
Microsystem’s SCADAPack 300 series.
“The SCADAPack E-series controllers are a com-
pletely distinct product line from the original
SCADAPack series,” said Dale Symington, VP product
strategy, Control Microsystems. “DNP3 and IEC 60870-
5 allow the slave controller to store a time-stamped
event whenever data points change and the continuous
recording means there are never holes in the data even
when communication links go down.”
The IEC 61131-3 programming environment pro-
vides support for two logic applications running simul-
taneously on the same E-series controller. Integrators
can load their own password-protected application offer-
ing core functionality for the market industry, while
leaving the second application for the end-user to add
custom control if needed.
E-series controllers support a full-featured FAT32
(PC compatible) file system and command line. The
command line provides direct access to the file system
and configuration commands that would otherwise be
sent via the E-series Configurator software, and it is
accessible over FTP, Telnet, DNP3 or local serial port.

NDSL Cellwatch
has released its
Cellwatch Central, a
server application
that constantly moni-
tors multiple
Cellwatch systems
over an internal net-
work or across the Internet.
“Until Cellwatch Central,” said David Brown, CEO,
Cellwatch, “corporate and government entities with
multiple buildings and multiple battery rooms have had
limited options for pulling their battery monitoring sys-
tems together on one screen. Cellwatch Central pulls
together the condition and alarm data from different
Cellwatch systems on one server and then provides data
to multiple web viewers throughout a network.”
Remote users can view and interact with real-time,
summary condition data such as alarm status, battery
condition and alarm history. Cellwatch Central uses a
standard web browser and consolidates the data on a
dedicated desktop or rack mount server PC.

ComBrio Releases VSI AutomationAnd Control for RemoteMonitoring and Management
ComBrio, Inc. has expanded its virtual service infra-
structure (VSI) product suite to address the needs of
enterprises in the automation and process industries for
secure and controlled remote access of their automation
and process-control network environment.
VSI Automation and Control is the first complete
RPS suite that provides plant managers and automation
engineers a cost efficient and secure solution for remote
monitoring and management of SCADA elements and
applications such as programmable logic controllers
(PLCs), distributed control systems (DCS) and master
control units (MCO). The purposely built RPS solution
addresses the end-to-end needs of plant managers by
providing them with a homogeneous platform to address
both internal access controls, along with third party ven-
dor services into automation network environments.
Through the use of VSI Automation and Control,

of their process-oriented and discrete control systems.
The VSI solution allows remotely located support and
service personnel with the ability to gain secure, con-
trolled and accountable access to SCADA devices locat-
ed behind the operations network firewalls.
“There have been many advances in embedded man-
agement of today’s automation/process control equipment,
said Dave Boulos, vice president of product management,
Combrio. “This coupled with the adoption of Industrial
Ethernet for SCADA inter-device and inter-vendor com-
munications, has opened up the opportunity for plant man-
agers to improve productivity and increase uptime by
leveraging a centrally located or distributed resource pool
to monitor and service plant network segments remotely.

Tollgrade Launches DistributionGrid Monitoring Product Line
Tollgrade Communications, Inc. has launched a cen-
tralized remote monitoring system, called LightHouse.
This line provides a means for electric power utilities to
deploy technology for real-time grid intelligence, imme-
diately detect faults, help to minimize the impact of out-
ages and optimize utilization of assets, with a goal to
improve overall efficiency of energy delivery.
A LightHouse sensor, mounted directly on the electri-
cal conductor, continuously monitors key circuit parame-
ters and transmit data over a wireless network to a central
location, reducing time of detecting a problem on the
grid, identifying its location and restoring service.
“For many years the distribution grid relied on
visual observation from field crews or calls from
customers to alert the power company of a prob-
lem,” said Steven Day, executive director,
Tollgrade. “We recognized a compelling need for
robust and flexible sensor technology in a mar-
ketplace that requires continuous performance
and in an industry that is seeking ways to opti-
mize the performance of distribution grids.”
The LightHouse product line is a system of com-
ponents that includes a wireless sensor, an aggrega-
tor device that collects data, and software that will
enable viewing, maintenance and reporting func-
tions in real-time. The line has been in development
for more than a year and is available as a beta prod-
uct for utility evaluation pilot programs.

GE Fanuc Intelligent PlatformsLaunches Proficy HMI/SCADACimplicity 7.5
GE Fanuc Intelligent Platforms has released the latest
version of its supervisory control solution, Proficy
H M I / S C A D A
Cimplicity 7.5, offer-
ing diagnostic tools,
security, development
tools, connectivity
and flexibility.
“Cimplicity 7.5
extends the product’s
ability to develop and
improve supervisory
monitoring and control projects,” said Gimmi Filice,
Cimplicity product manager, GE Fanuc. “Whether
upgrading an existing system, or implementing a new
project, Cimplicity 7.5 will provide users with the power,
flexibility and ease of use they need.”
Some of the notable enhancements are digital graphi-
cal replay (DGR), enhanced screen navigation, and
easy-to-use application deployment. The digital graphi-
cal replay, part of the enhanced screen navigation,
allows users to go back in time and replay Cimplicity
screens based on logged historical data. Events can be
replayed in real time, slow motion or fast forward to
analyze systems leading up to alarms and trouble shoot
or optimize applications.
A new timesaving capability for developers and oper-
ators is the screen navigation bar. Frequently,
HMI/SCADA developers add a method of navigation to
their application, requiring them to build buttons or
frames containing links to other screens. Cimplicity 7.5
has made configuring navigation as simple as drag and
drop. By dragging screens into a hierarchy, users can
build a task bar menu, with options to color code and
have other attributes so that operators can locate screens
quickly and make them more effective.
To facilitate time-consuming deployment of changes
in large applications, Cimplicity contains an application
deployment system to allow development changes to be
propagated automatically to all the viewers in the sys-
tem helping reduce total cost of ownership. By simply
configuring when and how you want to deploy the
changes, viewers will then detect changes, copy the
necessary files and alert the operator that changes are
coming that can be deferred if needed, or configured to
force the change.
In addition to the standard client/server architecture in
Cimplicty, an advanced viewer gives even more flexibil-
ity for how to architect a system. The advanced viewer
allows users to visualize data captured by the server just
like the standard viewer, with the option of capturing data
directly from OPC DA servers locally or on the network.
Often applications need simple enhancements or the abil-
ity to grab a piece of information local to the viewer.
Rather than going to the server and configuring a data
point to make the data available to the viewer, the view-
er can access the OPC data directly. This provides flexi-
bility in architecture, and the ability to enhance the local
application without modifying the server.
With the growing need for securing HMI/SCADA sys-
tems, and the increased dependence on IT standards,
Cimplicity has added Windows Domain Security integra-
tion. This allows users to take advantage of current IT
configurations, so that they can assign roles and
resources in Cimplicity based on Windows groups. The
software will use the configured Windows Domain to
authenticate user credentials and the IT rules that come
with it for password expiration, rules and more.
With the release of Cimplicity 7.5, GE Fanuc has
increased the value of the combined Cimplicity and
Proficy Historian solution. Enhancements to the integra-
tion allow users to log alarm data to Historian in addition
to data that was already logged there. Additional flexibil-
ity allows you to configure the system to log to SQL his-
torian or both, or split up the data and alarm logs.
National Instruments Expands CSeries Family for High PerformanceData Logging
National Instruments has released four new C series
modules for data-logging applications including vibra-
tion/acoustical data logging and temperature and pressure
testing. The NI USB-9219, USB-9229 and USB-9239
provide USB, bus-powered connectivity to the C series
while the NI 9234 AC/DC-coupled dynamic signal acqui-
sition module
offers selectable
IEPE signal condi-
tioning for engi-
neers measuring
h i g h - a c c u r a c y
audio frequency.
The C series
combines signal
conditioning, direct sensor connectivity and data acquisi-
tion into a small module for each measurement type that
can be inserted into any C series chassis to create a vari-
ety of systems. There are more than 40 C series modules
available for different measurements including thermo-
couple, voltage, RTD, current, resistance, strain, digital
(TTL and other), accelerometers and microphones. The
new modules, which expand the NI offering of 24-bit C
series modules for data-logging applications, are
enhanced with the inherent data acquisition and analysis
features of NI LabVIEW software.
The bus-powered four-channel universal C series
modules are designed for multipurpose testing in any NI
CompactDAQ or CompactRIO chassis, or with the NI
USB-9162 single module carrier. With the new USB-
9219 universal module, engineers can measure up to 11
types of signals from sensors such as strain gages, RTDs,
thermocouples and load cells. With channel-to-channel
isolation, an entire system, including the device under
test, is protected from harmful voltage spikes up to the
isolation rating. In addition to safety, isolation eliminates
measurement errors caused by ground loops.
Measurement ranges for the USB-9219 include up to
±60 V and ±25 mA, making it well suited for in-vehicle
data-logging applications that often require 12 V or 42 V
of measurement range. The USB-9229 and USB-9239
high-speed data-logging modules acquire 50 kS/s sam-
ples per second per channel and include anti-aliasing fil-
ters to eliminate unwanted signals for monitoring appli-
cations such as structural health, machine conditioning,
electrical power and environmental monitoring. The
USB-9239 operates at ±10 V for precise, high-speed sen-
sor measurement, while the USB-9229 operates at ±60 V
for sensors with a higher output range such as proximity
probes used for vibration data logging.
The NI 9234 dynamic signal acquisition module is
more suited for vibration and acoustical data log-
ging because engineers can turn on or off IEPE
conditioning as well as select AC or DC coupling.
The module delivers 24 bits of resolution, 102 dB
of dynamic range and anti-aliasing filters. The NI
9234 module can be used with the NI Sound and
Vibration Measurement Suite, which includes the
Sound and Vibration Assistant to simplify acquir-
ing and analyzing noise and vibration signals by
offering a stand-alone, interactive analysis and
acquisition environment. The stand-alone soft-
ware makes it possible to continually interact
with varying data analysis settings while logging
data to disk for future analysis.
Engineers can use C series modules with the
USB-9162 single module carrier and NI
CompactDAQ and CompactRIO hardware.
Combining this hardware with LabVIEW soft-
ware creates a user-defined data-logging applica-
tion. With LabVIEW graphical programming,
engineers can create custom user interfaces and
take advantage of more than 600 math and analy-
sis functions.

advanced algorithms to discern the acoustic sig-
nature of leaks from background noise. Leak
noise data is collected by the RoadRunner Mobile
or handheld that is simultaneously performing
normal automatic meter reading (AMR) opera-
tions. A digital leak noise correlator can then be
used to pinpoint the leak’s location. Armed with
this precise location information, repair crews can
quickly find and repair leaks.
"A single eight-gallon-per-minute leak will
waste more than four million gallons of water in
a year, said Rich Sanders, business development
manager, Datamatic. “Small leaks that stay hid-
den eventually become big leaks, causing main
breaks, sinkholes, flooding and serious service
disruptions. This new system will allow commu-
nities to quickly identify and fix leaks, conserving
valuable resources."
New Panel Meter Features Built-In Outputs with DualSetpoint Capability
Red Lion Controls, Inc. has introduced the
Paxla, an extension of the company’s series of
Pax Lite panel
meters. This meter
is the first Pax Lite
model featuring
control capability
by adding two
Form C relays
capable of switch-
ing up to 5 amps. Paxla can accept DC current,
DC voltage or process input signals, scaling them
to a desired readout for a wide range of applica-
tions. Plus, the Paxla is simple to program using
its front panel buttons and jumpers.
Paxla delivers a bright five digit, 0.56 inches
high red LED display with programmable scaling
and decimal points. In addition, it offers a newly
designed universal power supply, accepting 50 to
250 VAC or 21.6 to 250 VDC. In addition a 24
VDC excitation output is available for increased
application flexibility. Plus, once front panel pro-
gramming is complete, the front panel buttons
can be disabled through a user input setting.
Paxla meets CE requirements and features a
NEMA 4X/IP65 sealed front bezel, providing
excellent reliability in harsh industrial environ-
ments. In addition, Paxla features an optional cus-
tom unit overlay with backlight, and it offers min-
imum and maximum display and capture.
Brooks Instrument EnhancesIts 4800 Series Mass FlowMeters/Controllers
Brooks Instrument has made several updates to
its latest mass flow meters/controllers. The model
4800 series now has digital
communications via RS-232
and a downport connection
option. In addition, it is the first
of Brooks' mass flow devices to
be fully RoHS compliant.
The RS-232 digital, one-to-
one communication protocol
allows the customer to provide a
setpoint and receive the process
value, select one of nine gases for the calibration curve,
access the valve override function, and access the re-zero
function. The RS-232 protocol will come built-in to the
product as part of its standard package.
Optional downport connections are also available on the
4800 mass flow meter/controller. In order to keep the advan-
tage of the 4800 series small footprint, Brooks utilized a
proprietary standard downport option. This option allows
top mounting for ease of maintenance and installation and
also offers additional space savings over traditional mount-
ings because there is no point-to-point tubing necessary.
The RoHS Directive places restrictions on the use of
certain hazardous substances in electrical and electronic
equipment. This directive bans new electrical and elec-
tronic equipment containing more than agreed levels of
lead, cadmium, mercury and certain other materials from
being distributed in the EU. The 4800 series is Brooks'
first, fully RoHS compliant MFC.

Uplogix Enhances Secure Remote ManagementAppliance for Managing Distributed Networks
Uplogix has announced the
general availability of Envoy
and Envoy Management Station
(EMS) v3.4, a fully-integrated
remote management platform.
The enhancements in this new
version helps large IT organiza-
tions further automate routine maintenance and recovery tasks to alleviate the risks,
complexity and costs in managing dispersed networks.
“Remote management is an area we are seeing a lot of demand in by our customer
base,” said Chris Boykin, CEO, Got Net Security. “This new version has allowed us to
expand our service offering to include an intelligent product that will more than meet
customer expectations of what an integrated remote management appliance can do. As
network architecture and IT infrastructures become more increasingly complex, new
approaches and technologies like Uplogix are required.”
Version 3.4 of Uplogix’ architecture integrates an always-available, secure and intel-
ligent direct connection to the remote devices it manages. In comparison, traditional net-
work management tools are not equipped to automate routine maintenance and recovery
tasks because they depend on the network being available, and thus rely on people to do
the work. The Uplogix solution is a new approach that significantly reduces labor costs
and allows IT professionals to focus on more critical responsibilities.
One of the enhanced features includes improved user authentication flexibility. By
enhancing the security model to expand beyond global settings, IT administrators now
have the ability to choose user authentication options on a more granular level, prom-
ising only the right users have the right access to the right devices. Envoy integrates
with the third party authentication systems including TACACS, RSA SecureID, Secure
Computing’s Safeword and Radius. Envoy also supports bonding between primary and
secondary Ethernet ports. If a connection to the primary interface is lost, Envoy can
failover the secondary interface, ensuring devices are always accessible and available.
Formerly transferred through Secure Copy Protocol (SCP), data files capturing device
changes such as configurations, alerts and events, can now be archived more efficiently
through a HTTPS session. Configuration and key management challenges are mini-
mized, thus improving overall performance of large enterprise-wide implementations.
Uplogix has developed an SRM appliance that integrates critical access, control and
enforcement (ACE) remote management functions to alleviate the risk, complexity and
costs inherent in managing distributed IT infrastructures such as branch offices and
remote datacenters. This includes secure always-available access to distributed devices,
as well as local automation and control of routine maintenance, configuration and
recovery tasks.

RLE is First to Introduce Distance Read LeakDetection with Ethernet Capabilities
RLE Technologies has released of the
SeaHawk LD2000, a Web-enabled, distance
read leak detection system. The LD2000 pin-
points the location of any conductive fluid on
up to 2,000 feet of RLE patented SeaHawk
Leak Detection Cable (SC).
The SeaHawk LD2000 is designed to work
in conjunction with SC cable. When a conduc-
tive fluid comes in contact with SC cable or SeaHawk zone spot detectors (SD-Z), the
system pinpoints the location of the leak. Within seconds, the LED flashes in alarm and
the LED display provides a distance measurement so that the location of the leak can
be determined.
Unlike any leak detection system on the market, the LD2000 system includes features
such as direct alarm notification via email or SMS to cellular devices, and a Web inter-
face that allows users to view status and modify system configurations. Notably, the
LD2000 allows for simple integration with existing building management systems (BMS)
via Modbus and BACnet and/or network management systems (NMS) via SNMP.
Yokogawa Integrates Plant Resource Manager withPepperl+Fuchs FieldConnex Diagnostic Module

field device, enabling efficient root-cause analysis in real-time and keeping plants oper-
ating smoothly.
In addition to supporting the use of powerful tools such as oscilloscopes and data his-
torians, ADM’s unique commissioning wizard can reduce up to 80 percent the amount
of time required for the critical plant start-up phase. ADM’s online monitoring capabil-
ities provide actionable information through PRM’s user interface, indicating changes
in the fieldbus physical layer before they become critical. Via PRM R3.02, all infor-
mation can be displayed on the operator stations of Yokogawa's Centum VP production
control system.
The integration of the FieldConnex ADM interface has widened the scope of PRM's
asset management capabilities, helping operators make decisions by providing easy
access to actionable information on the health of their Foundation fieldbus segments,
therefore ensuring the maximum availability of the physical layer.
ZigBee and EOL Make ElectricOutlets Smart
Energy Optimizers Limited (EOL) has devel-
oped a ZigBee-based plug-in electricity meter
that can help companies and households shave
hundreds to thousands of dollars off their elec-
tricity bills. The UK company’s device, called the
plogg, allows home and building-owners to mon-
itor how much electricity is being used by indi-
vidual appliances and electronic devices so that
energy efficiency can be improved.
The plogg is a combined smart meter plug and
data logger, based
on Ember’s
ZigBee wireless
technology run-
ning on a
Telegesis module.
It can be attached
to any electrical
appliance or
device that uses a standard UK 13 amp or
European 16 amp plug. A plogg for the North
American market is currently under evaluation.
The plogg stores the measured electricity data
and wirelessly communicates this information to
a PC, mobile phone or building management sys-
tem anywhere in the world through an Internet-
linked Ethernet gateway. For instance, a restau-
rant chain could use ploggs to monitor energy use
by refrigeration and air conditioning units, with
all the information collected at a central point via
the Internet. Upon discovering that some air con-
ditioners were left on after business hours, the
plogg would allow them to switch off air condi-
tioning units by remote activation, or alert a man-
ager that a unit needs servicing. The plogg meters
can support a range of other wireless-based ener-
gy saving devices as well, such as temperature
and light level sensors.
Using Ember’s EM250 ZigBee “system-on-
chip” transceiver and EmberZNet PRO wireless
mesh networking software running on a Telegesis
module, a network of ploggs can self organize to
provide robust coverage of the home or building.
The plogg can act as an end device, a router or
ZigBee coordinator. It is available as a stand-
alone end-user device, or part of an energy report-
ing network, or as an embeddable device for
OEM products.
In addition to measuring power consumption, a
real-time clock function allows time-of-use
metering information for multi-rate applications.
Data logging can be set from one minute to one
month. The meter samples voltage and current
signals 50 times per AC cycle, at a sampling rate
of 2,520 Hz.
“Telegesis embedded devices provided us with
a straightforward, cost effective and importantly,
a quick route to market,” said Shaun Merrick,
general manager, EOL. “With the release from Ember of EmberZNet PRO 3.1, we now
have the means to deliver micro building management systems, incorporating compat-
ible energy controls such as light, presence and temperature sensors.”
The EM250 is an 802.15.4/ZigBee compliant semiconductor system that integrates a
programmable microprocessor, RF radio, network protocol stack and memory into a
tiny, single-chip solution (7 mm on a side). It offers EOL dramatic reductions in com-
ponent size, cost and power consumption, and increased range due to its very high sen-
sitivity. The EM250 runs EmberZNet PRO 3.1, Ember’s enhanced ZigBee PRO com-
pliant networking stack.

Rich Chaplin, Senior Project Manager CSI
In less than nine days, live, and with no downtime, the City of Phoenix Water
Department recently installed a new control system at its five-million-gallon-a-day
Cave Creek water reclamation plant. The following story tells how the City of Phoenix
Water Department was able to accomplish this feat, as well as drastically reduce devel-
opment time for its new five-site automation system. It also tells how the city is sav-
ing millions of dollars and thousands of hours by using
UCOS, a state-of-the-art distributed control system, at its
water/wastewater facilities.
Phoenix is one of the fastest growing cities in
America, and that has put enormous pressure on the
city’s water/wastewater requirements. With continued,
increasing growth, the City of Phoenix Water Services
Department needed to dramatically upgrade the automa-
tion efficiencies at all of its water treatment, waste treat-
ment, and reclamation facilities.
City Management staff and the City Auditor’s
Department management chose to install a UCOS sys-
tem developed by Control Systems International (CSI)
headquartered in Lenexa, Kan. This decision followed a
two-year, department-wide study that involved the
preparation of new, state-of-the-art process control stan-
dards and an evaluation process that has been thorough-
ly reviewed by Phoenix Water Services.
In the final evaluation, the patented UCOS system was chosen over Rockwell
Automation and Westinghouse Process Control as the best technology to meet the
future control system needs of the City of Phoenix Water Services Department.
“It is noteworthy that in addition to CSI being the lowest priced and most respon-
sive proposer, they also were the overwhelming choice of two separate evaluation
committees,” stated the Water Services Department’s funding request to the Phoenix
City Council.
UCOS is replacing existing systems that are “obsolete or systems of lesser tech-
nology” at four sites: the 23rd Avenue wastewater treatment plant, the 91st Avenue
wastewater treatment plant, the Union Hills water treatment plant, and the Cave
Creek reclamation plant. UCOS will also be installed at
the North Gateway reclamation plant, which is cur-
rently under construction.
CSI started by creating a detailed design document,
including functional specifications, implementation
standards for control strategies, human-machine inter-
face (HMI) graphics, and tag definitions. CSI then used
patented features in UCOS to embed those specifica-
tions into a water/wastewater-specific library of object-
oriented device templates. This device template design
process ensures consistent implementation of the speci-
fications throughout all the projects and any future
water projects.
UCOS greatly reduces system development time
because the UCOS device library of pre-configured,
pre-tested templates allows easy replication of devices
with just the click of a mouse. This enables me to
design control strategies in a visual environment with
logic and tag definitions graphically displayed. The functionality of the control
scheme can then be applied to any similar facility. In essence, once one water treat-
ment facility is designed with UCOS, the same pre-tested and pre-configured device
templates and control strategy can be applied to subsequent facilities. This has saved
the Phoenix Water Services Department hundreds of hours in development and
implementation time.
UCOS operates on Windows 2000 and is an open system that configures to most off-
the-shelf hardware. In fact, UCOS means User Configurable Open System. This also
saved the City of Phoenix Water Department time and money because they didn’t have
to replace any of the existing hardware and I/O subsystems at four plants.
The Cave Creek reclamation plant was CSI’s first cut-over. They started there by
creating a “maintenance of plant operations” document which detailed the functional-
ity of each of the plant’s four controllers. With that information, CSI could then deter-
mine the best sequence in which to replace the old controllers with UCOS field con-
trol units (FCUs).
At Cave Creek CSI replaced an obsolete and unsupported GE/Parsons-XLS DCS
with UCOS but did not replace any
of the OPTO-22 I/O. This saved
thousands of dollars because none
of the I/O had to be rewired, test-
ed, or debugged.
No fieldwork was required at
this site, and the cut-over was done
live, so there was no downtime for
the system conversion. This was
important in that the Enhanced
Surface Water Treatment regula-
tions require the plants to remain
“100 percent operational,” and that
plant continued to reclaim four to
six million gallons of water each day during cut-over.
Since the GE/Parsons system was originally installed with redundant controllers,
CSI simply unplugged one side of the I/O chain and plugged it into our UCOS FCU.
This was done sequentially with each I/O chain until all four UCOS FCUs were in
place and fully operational.
In all, 2,500 real-world I/O points and 1,000 Modbus protocol points are controlled
by three operator workstations, employing 135 HMI screens. What took CSI eight and a
half days to cut over would have taken at least three months, if not longer, for a standard
PLC system, and cut-over would have been tedious and difficult, at best. It is also doubt-
ful that a live cut-over could even be engineered in three months with a PLC system.
By not having to rewire any existing hardware, CSI removed part of the human error
element from the equation, and since this UCOS project is pre-configured and pre-test-
ed we were able to check our system interface in a matter of minutes. While preparing
for the Cave Creek cut-over, CSI also developed and implemented new procedures and
standards that will make all future cut-overs run even more smoothly.
Next CSI will cut over the Union Hill Water Treatment site, which treats 160 mil-
lion gallons of water each day. Currently, Union Hill operates on a Siemens/TI system

that uses Wonderware HMI, Siemens/Texas Instruments PLCs, and I/O. Managing and
enforcing standardization of this type of configuration is difficult, so the Phoenix Water
Services Department is having CSI replace the entire system except for the field wiring
and fiber network.
Phoenix Water Services wants to use Modicon I/O, so CSI will use the existing
wiring but replace all of the Siemens I/O racks with new Modicon racks. Since UCOS
interfaces with a wide variety of off-the-shelf I/O, we have configured the UCOS FCU
to scan the new Modicon Quantum I/O. One UCOS FCU can control up to four differ-
ent I/O brands at the same time.
Union Hill’s control stations are not currently integrated into the other Phoenix
Water Services DCS. As part of the automation project CSI will integrate those stations
into the UCOS system and also integrate the entire Cave Creek site into the system.
Since Cave Creek and Union Hill share some resources and personnel, both sites will
be managed as one.
UCOS will monitor and control two different kinds of I/O at the two different sites.
Both facilities will have the same look and feel on
the HMI screens, and personnel from either plant
will be able to operate Cave Creek from Union
Hill or vice-versa.
When all five plants are upgraded with UCOS,
operators who have proper security will be able
to monitor and control any other plant on the sys-
tem from any plant on the system. When the proj-
ect is completed, UCOS will monitor and control
more than 22,500 real-world I/O points across all
five sites.
In addition to the five sites mentioned, the
Phoenix Water Services Department has included
in the contract a 100-percent option clause, which
will permit it to install UCOS at five additional
water production sites in the future. And because
UCOS can readily adapt to new technology with-
out downtime, UCOS will help keep the City of
Phoenix’s water and wastewater facilities operat-
ing smoothly, efficiently, and cost-effectively
long into the future.

Everyone knows the theory “quality over quantity.” This is especially true in the envi-
ronmental monitoring system industry, where the emphasis is not on simply having a
system but rather on the quality of the system that makes it one that you can depend on.
What good is an environmental monitoring system that cannot be relied on for contin-
uous, 24/7 supervision? Considering that the demand for such systems is based on the
security they provide, it would be pointless to invest time and money into a monitoring
system that is not completely reliable.
Now, how would one describe a monitoring system that continues to monitor and
record data, even during network outages? That answer is much more definite
because reliability is what the end-users of monitoring systems would rather invest
their efforts and capital budgeting in. The manufacturer of such systems has listened
to the need for a high level of security and reliability, and the environmental moni-
toring systems that are developed with this in mind are on the highest quality level
and worth every penny of investment.
Because choosing a monitoring system is such an important decision, it should not be
taken lightly. It should entail research and comparison shopping on the part of the end-
user. Since the industry for these systems provides as many options as it does applica-
tions, it often becomes difficult to sort through the variety of manufacturers and their
offerings. When an end-user knows what he or she expects from an environmental mon-
itoring system, it becomes much easier to narrow the choices. An example of the gen-
eral system architecture below shows how simple an environmental monitoring system
can be, allowing end-users to easily understand the process.
The motive for the investment in a monitoring system is the security it provides facili-
ties, and as the demand for monitoring systems increases, so does the end-user’s expec-
tation for the level of reliability and security it promises.When failure is simply not an
option, end users should look for the following capabilities in a monitoring system to
create a low-risk environment:
Redundant Sensors These sensor probes got their name by having two intelligent sensors built in each,
which are self-validated every time a measurement is taken. Instead of relying on a
single sensor, both sensors monitor the desired parameter. Therefore, redundant sen-
sors simultaneously collect data from a single source but have the values for two
exclusive measurements. The monitoring station instantly compares the two values
reported by the sensors, and if they have a difference greater than desired, warnings
are dispersed to the proper personnel. This provides the ultimate in reliability by
adding another sensor in each probe, and essentially, creating a monitoring system
within itself for a very reasonable cost. Many parameters, such as temperature, which
is the most common, can be measured by redundant sensors, expanding this useful
characteristic to the monitoring of humidity, differential pressure, CO2 levels and
much more. Relying on twice as many sensors without increasing the number of
probes is as important to ensuring reliability as it is unique to the industry.
Localized Alarm Processing Alert capabilities are one of the most important functions of a monitoring system
since alerting key personnel to evolving situations allows them to take the necessary
actions to avert a pending problem. Another way to obtain a highly reliable monitor-
ing system is to have warning and alarm capabilities housed within the monitoring
station that is directly connected to the sensors. Therefore, if a network failure, server
outage, or LAN drop occurs, the alert capabilities remain on guard, continue to func-
tion properly, and alert personnel of abnormalities via local visual and audible alarms.
A simple pushbutton should be provided to acknowledge and silence the alarm while
the problem is being addressed. This makes the monitoring station distinctive in this
aspect because, unlike typical systems, it does not completely rely on the server to
process and send alerts. Monitoring systems that do not have local alarm processing
lose the ability to alert personnel of problems in data during network outages that
cause the server to go offline. However, the monitoring station’s localized alarm pro-
cessing still continues even when the server or network is down, making the system
fault tolerant, fool-proof, and anything but typical.

Data BufferingWhen communication faults occur, there can be gaps in collected data. To prevent this,
monitoring stations should have the ability to buffer continuously and store all data
within until the connection is re-established. Having at least sixty hours of local data
storage during communication faults should suffice through most server or network
problems. One of the system’s major strengths is its I/O flexibility and the ability to
communicate over standard Ethernet networks to monitor remote locations. Networks
do occasionally go down, so monitoring stations are designed to continue handling the
imperative functions. Comparing this again to a typical system that loses alarm capa-
bilities, a typical system also does not prevent gaps in data. This is another example of
how the one-of-a-kind monitoring station is a hardware component that never, ever
stops monitoring, recording, and alerting, and, as a result, enhances the dependability
of the remote monitoring system as a whole.
Battery Back UpThough battery back-up is seemingly the sim-
plest characteristic of a secure monitoring
system, its importance is not overlooked.
Having a reliable battery back-up is the pred-
ecessor to all of the capabilities previously
mentioned. This provides a low cost of own-
ership since the use of lithium batteries can
power the monitoring station for multiple
years, depending on the number of outages.
This means that battery replacement is rarely
required and only after an unusually long
series of power failures. In conjunction, the
system should monitor its own battery power
supply by sending alerts when replacements
are needed. Again, this exemplifies a monitor-
ing system that can be relied on for its
automation, therefore relieving the burden
from the shoulders of facility managers.
The system described here has a solution that
fits a broad scope of needs for years to come.
All of these key functions ensure the reliabili-
ty needed by both facilities and the organiza-
tions that accredit them. Implementing a sys-
tem that not only meets, but exceeds standard
requirements allows end-users to have a mon-
itoring solution for the present and future.
All in all, these four important components
and characteristics, redundant sensors, local-
ized alarm processing, data-buffering and bat-
tery backup, work together to ensure that a
monitoring system runs continuously and
accurately, even during server problems, net-
work outages, and LAN drops. Purchasing an
environmental monitoring system without
these key features would be a loss for any
facility. To ensure a low-risk environment and
money well-spent, ask about these offerings
when deciding which system to implement for
the years to come. Make sure that your effort
is worthwhile by purchasing and implement-
ing a system that never leaves you stranded.
The purpose of a monitoring system is to consistently watch over sensitive materials,
where failure is not an option. Keep this in mind as you search for an environmental
monitoring system that you can understand and count on, and it will the best co-work-
er one could ever ask for.

Changing Business ClimateAging infrastructure, new state and federal regulations, new unfriendly neighbors, an
aging workforce and heightened security restricting site access are burdening company
operations with increasing costs and deteriorating operational excellence. Operating
managers within energy, municipal and pipeline companies look to extend their invest-
ment in high performance SCADA networks in the hopes of gaining greater operational
efficiencies and keeping costs in check.
Likewise, operation professionals look to their investments in SCADA networks and
remote automation also to gain new operational efficiencies. Originally planned for
integration to remote terminal units, and programmable logic controllers, SCADA sys-
tems now are used for AMR/AMI applications, and operators are looking for even
greater leverage of their existing systems.
A New DirectionA large municipal water company in Denver, Colo. is experimenting with a new,
low-cost remote monitoring solution specifically designed to monitor integrity man-
agement and corrosion prevention systems. Leveraging its existing SCADA infra-
structure, it hopes to extend remote monitoring to critical cathodic protection systems
as well.
Cathodic Protection (CP) systems for storage tanks, pipes and other buried infra-
structure are often located in remote locations making them difficult to maintain and
operate, let alone operate at peak performance. In some cases, unauthorized third par-
ties strip the critical rectifiers and wiring and sell them for scrap, leaving tanks and
miles of expensive metal unprotected. Theft results in an increased risk of damage or
even total failure of a system from corrosion. Compounding operational difficulties of
remote systems are site access issues stemming from land use disputes, Homeland
Security and urban sprawl.
The cost of implementing properly installed and well-maintained CP remote moni-
toring equipment pales in comparison to the annual costs required to repair even a sin-
gle leak. Reports estimate corrosion is responsible for costing US industries more $270
billion per year, almost 3.1 percent of the GDP. The desire to reign in those costs has
never been greater. Corrosion leading to leaks, lost revenue, groundwater contamina-
tion and other adverse scenarios affecting overall water quality, supply and/or public
safety now can be prevented like never before through technological advances in the
remote monitoring of critical tanks, pipes and casings.
Since the 1800s, when the first metal pipe was buried in North America, roughly 2.3
million miles of pipe and corresponding valves, tanks, vaults and structures were buried
to carry vital water supplies across the country. Much of this buried infrastructure now
celebrates its 50th year and some of this infrastructure is beginning to show its age by
a few notable, recent and tragic events.
As tank and pipeline grew
operations throughout North
America, so grew federal and
state regulations governing the
industry. Recent legislation
passed by the US Congress fur-
ther develops the legal implica-
tions of pipeline integrity man-
agement. At the heart of this
growing legislative effort is the
protection of public safety, the
environment, irreplaceable
national energy reserves and the
US economy.
Recent tragic events at the local, state, national and international levels place increas-
ing focus on the protection and integrity of all US pipeline operations. Evidence of this
increased national public awareness is demonstrated by the recent passage of the
Pipeline Safety Improvement Act of December 2002, and the Pipeline Inspection,
Protection, Enforcement and Safety Act of 2006. Both Acts serve not only to illustrate
growing awareness, but also to educate the industry on pipeline operation best practices.
The Pipeline Safety Improvement Act of December 2002 mandates significant
changes and new requirements in the way the pipeline industry ensures the safety and
integrity of its pipeline facilities, including:
• Each pipeline operator must prepare and implement an Integrity Management
Program (IMP)
• Participate in planned-excavation one-call notification programs
• Increase the penalties for violations of safety standards
• Authorize state participation in interstate pipeline oversight
• Offer a multi-agency program of research, development, demonstration and
standardization to enhance the integrity of pipelines
• Develop an inter-agency task force to expedite environmental reviews when
necessary to expedite pipeline repairs
Pipeline Inspection, Protection, Enforcement and Safety Act of December of 2006
requires certification procedures of annual and semi-annual pipeline integrity reports by
a senior executive officer of each pipeline company to certify that the officer has read
the report and, to the best of the officer’s knowledge, that it is true and accurate.
Site access issues stemming from land use disputes, Homeland Security and urban
sprawl, compound operational difficulties for remote systems. Recent tragic interna-
tional events led many landowners, municipalities and government agencies to restrict
access to sensitive areas making them onerous to enter for maintenance purposes. Many
airports, office towers and mass transit sites are now “off ls” for routine CP mainte-
nance checks. Restrictive site access procedures leave miles of buried infrastructure
unmonitored and sometimes unprotected.
Rising energy prices, steel prices and labor costs add to operating budget shortfalls.
The cost of repairing or replacing buried metal assets steadily rose over 300 percent
through the last 10 years and is projected to continue. One analyst speculates that
pipeline integrity issues alone could drive energy prices higher by 27 percent.
New Development in FHSSNew spread spectrum wireless data communication technology, first developed in
the 1930s, known as Frequency Hopping Spread Spectrum (FHSS), is based on the con-
cept that most radio frequencies are underutilized. FHSS allows multiple users to simul-
taneously operate across a spectrum of radio frequencies. Provided all radios within the
data communication network operate at the same frequency and then all hop to new fre-
quencies at the same time and in the same hopping pattern; then effective, safe, trouble
free data communications exist.
An analogy of FHSS technology is illustrated by imagining a group of people wish-
ing to carry on a conversation using Citizen Band (CB) radios. As long as all parties are
on the same channel, they can communicate, and if they wish to keep others out of their
conversation, they can carry on a private conversation by all agreeing to move from CB
channel to CB channel on a random, yet, agreed upon, pattern of CB channel hopping.
As long as all parties hop from channel to channel on the same pattern, at the same time,
they can carry on an effective conversation. If they take roll call upon arrival at the new
channel, they can further improve communication security. In some remote cases where
a third party does hit the current CB channel at the right time, they only get part of the
message, which means little to the third party.
FHSS Cathodic Protection Remote Monitoring TechnologyKey advantages of this new technology as applied to remote monitoring include no
monthly recurring fees or costs, no initial or monthly licensing fees, no lengthy legal
contracts, minimized network interferences, network security and it operates behind

company firewall. Additional benefits include
ownership of data, open protocol communica-
tions, system flexibility, infinite repeatability,
maximum implementation into cabinetry and
minimized field wiring
The new FHSS wireless CP remote monitor
units (CP RMUs) automatically monitor and
report key corrosion protection activities includ-
ing pipe-to-soil potential, rectifier output volt-
age, rectifier output amperage, rectifier input
power status, critical bonds, interference points
and interruption control. Modern CP RMUs
monitor ambient temperature and, if connected
to a solar power generation system, also will
monitor the back up battery supply voltage.
The new FHSS wireless field located CP
RMUs remotely monitor rectifier and pipe-to-soil
voltages, currents and potentials and record them.
Field data then is wirelessly collected from the
field devices by a computer located in a central
office or through a SCADA system for CP opera-
tor evaluation and monitoring.
Cathodic protection systems are highly sus-
ceptible to transient lightning surge. In addition
to being directly connected to the field piping
structures, CP rectifiers are also attached to over-
head power lines making them more likely to
receive damage from near strike lightning. To
protect sensitive wireless electronics, manufac-
turers use fully isolated relay, sampling capacitor
technology for maximum protection.
SCADAMany companies already own and operate a
SCADA network and can easily integrate these
new remote monitoring devices through existing
RTU’s, PLC’s or radio networks.
For companies that don’t have SCADA, they
can deploy, low cost data logging software readi-
ly available for less than the cost of a desktop
computer. Below, is an example of this new CP
data logging software.
Central data collection systems automatically
inform CP Professionals of immediate system
operation requirements leading to optimization in
keeping critical CP equipment online and operat-
ing within guidelines. As a result, remote sites no
longer are difficult to monitor.
Take a Test Drive Before You BuyA great way to learn more about new CP
remote monitoring technology is to test drive it
before you buy. Manufacturers offer no obliga-
tion, demonstration systems prior to making key
purchasing decisions. A test drive is easy to
implement by first selecting a half dozen test
points and a central office location and by pro-
viding the manufacturer or vendor with the site
coordinates. For the purpose of the test drive, CP
data either can be collected using the data logger
software or by coordinating with your CP RMU
provider to design a plan to integrate the equip-
ment into the existing SCADA architecture.
Normal test drive intervals depend largely on the size and type of system deploy-
ment. However, 30/60/90 day test drives are not uncommon.

Laird Technologies, Inc. has released a new generation of intelligent wireless mod-
ules from its EZURiO business unit. These modules allow M2M designers to quickly
add 802.11 connectivity to virtually any product at a low cost.
Despite the millions of available Wi-Fi access points, it is
difficult to embed wireless connectivity into machines.
Laptops are typically the only devices utilizing wireless
capability, until now. EZURiO’s intelligent wireless mod-
ules allow designers to connect devices not previously con-
nected in three steps.
For existing products, EZURiO’s cable replacement mode
provides an automatic, ad-hoc, configurable link between
products with no need for any hardware or firmware changes
beyond connection to an RS-232 port. Products with an on-
board processor can be modified to enable wireless connec-
tivity by using the high-level control interface of EZURiO’s
802.11 modules. All the designer needs to understand are
basic concepts such as search and attach to design a fully con-
nected product.
For new product designs, the internal processing power of EZURiO’s modules can
replace the need for any other processor. Coupled with UWScript, a fully featured and
wireless-aware scripting language, complete products can be designed around
EZURiO’s modules. These modules allow designers to bypass the steep wireless
learning curve and evolve from concept to production in applications such as remote
metering, ePOS, fleet management, energy conservation and more.
EZURiO’s pre-approved, dual processor 802.11 modules
bring wireless connectivity into the scope of any product, how-
ever meager its processing capabilities. Little bigger than a
postage stamp, the modules include a complete 802.11 device
server, a UART interface for data and control, 12 GPIO lines,
and two 10-bit ADCs. A tightly integrated web server can
access these signals for remote display or accept external con-
trol commands. One of the processors also runs an embedded
interpreter with EZURiO’s UWScript language, providing full
wireless connection control, as well as the capability to auto-
run user application scripts.
These feature-rich wireless LAN modules are 25 by 35 mm
in size, include industrial strength WLAN drivers and TCP/IP
stack, full UART interface, secure WEP and WPA2 implemen-
tation, as well as Bluetooth co-existence and co-location support.
Its low-power operation is well suited for battery powered applications and are avail-
able with either an integrated or external antenna. A low-cost development kit is
available for fast prototyping.
EZURiO, Ltd. Introduces New Intelligent Dual Processor 802.11 Modules
recently released Real Time Module for obtaining nearly
instantaneous physics-based path loss predictions for
communication links in urban environments.
"Most of the enhancements in Wireless InSite Release
2.4 are aimed at providing fast and accurate EM propa-
gation solutions to engineers engaged in the analysis and
design of wireless communication systems," said Joseph
Schuster, project supervisor, Remcom. "Improvements to
the interface and the way that information is organized,
as well as the availability of several time-saving mod-
ules, enable users to achieve faster results."
Wireless InSite allows RF communications engineers
to accurately analyze the impact of the physical environ-
ment on the performance of wireless communication sys-
tems. The software provides a broad range of site-
specific predictions of propagation and communi-
cation channel characteristics in complex urban,
indoor, rural and mixed path environments. In
addition to modeling the blockage and scattering
of the signal produced by the physical environ-
ment, the solutions also account for any changes
in the received signal due to using directional
transmitting and receiving antennas.
A key advantage of Wireless InSite is its use-
fulness for a wide variety of purposes. These
range from communication system planning to
performing more fundamental electromagnetic
wave propagation analyses. The software's flexi-
bility is the result of combining physics-based
numerical methods with a user interface that is
well-stocked with features.
The Release 2.4 user interface module runs on
the Windows XP and Vista operating systems.
The propagation analysis modules run on both
Windows and Linux operating systems and can
take advantage of multiple processors to reduce
the computation time.
T1/E1 Over IP Gateway Features Low Latency and isIndustrial Hardened
Featuring low latency and an industrial hard-
ened option, the new model TC3845 T1/E1-over-
IP-Gateway from TC Communications brings
added flexibility to IP network connectivity.
Compact and simple to configure, the TC3845
achieves absolute minimal latency (end-to-end
processing delay) by using high-performance
buffering and forwarding technology. The unit
transmits four channels of T1/E1, or any combina-
tions, over Layer 2/3 networks in point-to-point or
multi-point applications. Key features include traf-
fic monitoring and statistics, network time server
(NTS), remote firmware upgrade and temperature
monitoring. Typical applications include extending
voice, video and data across IP networks.
Each T1/E1 channel is independent and trans-
parent to protocols and signaling that run over
T1/E1. All applicable standards and line codes
are supported. For proper functionality, each T1
and E1 channel utilizes 6 Mbps and 8 Mbps of
bandwidth, respectively.
Setup, diagnostics and management are
accessed via Web, SNMP, serial console and
Telnet. Diagnostics include LED indicators and
local and remote loopback to assist with trou-
bleshooting and maintenance. The TC3845S
offers Rate Limiting on bandwidth utilization and
supports QoS for packet prioritization. Power
redundancy is standard. An extreme temperature version
is also available with an operating temperature range of -
40°C to 80°C.
Trango Releases Carrier EthernetMicrowave Backhaul Solution

AES-IntelliNet Introduces New FullData Internet/Radio AlarmCommunications Modules
AES-IntelliNet has introduced a new Full Data
Module named the AES 7090 VoIP-TAP. This product
was created to address problems the security industry has
experienced over the past several years, which include
the rise of VoIP, the demise of plain old telephone serv-
ices (POTS) and the technology standards obsolescence
with cellular communications. The VoIP-TAP is designed
to enroll seamlessly to the AES-IntelliNet mesh alarm
communications networks.
The AES 7090 VoIP-TAP product represents the latest
version of the AES 7067 IntelliTap Full Data Module.
The AES 7090
VoIP-TAP pro-
vides for dual-
communicat ion
via the Internet
and AES-
IntelliNet mesh
radio. The VOIP-
TAP sends full
data to be
received by the
AES Central
Receivers and incorporates all current functions and
capabilities of the AES 7067 IntelliTap. In addition, the
new VoIP-TAP data module allows the AES-IntelliNet's
MultiNet system to communicate directly with the digi-
tal dialer communicator within the alarm panel and takes
advantage of existing broadband connection within the
alarm communications subscribers.
The added features and functions are in response to
problems the security industry has faced and is facing
now including, alarm panel incompatibility with Voice-
Over IP networks, the unavailability of telephone lines in
the protected premise and avoiding the disruptions and
costs encountered when cellular technology standards
change as recently experienced with the AMPS issue.
The AES-IntelliNet's alarm system is a self healing,
long range wireless mesh radio communication network
and works in conjunction with the Internet to provide
customers the ability to monitor alarms in multiple
regions from one location, without recurring monthly
communications costs or infrastructure fees typically
associated with remote monitoring. The AES-IntelliNet
mesh network also offers a more reliable, faster means of
communicating alarm signals to central monitoring sta-
tions without relying on telephone lines or cellular serv-
ices that are vulnerable to line cuts, weather conditions,
radio jamming and recurring monthly costs.
Firetide Introduces Wireless Public Safety Tri-Band Mesh andAccess Infrastructure
Firetide Inc. has added tri-band (2.4, 4.9, 5 GHz) capa-
bility on its HotPoint access points and HotClient client
premises equipment (CPE) to augment the tri-
band functionality of its HotPort mesh nodes. The
combination of user-controlled spectra, indoor
and outdoor configurations, backhaul perform-
ance of up to 70 Mbps and end-to-end manage-
ment provides Firetide customers with added
flexibility for public safety, commercial security,
municipal and industrial deployments.
“The option of using licensed or unlicensed
bands in mesh and access networks allows public
safety agencies to choose the band that best fits a
particular area to maximize coverage or reduce
interference,” said Detective Chris Jensen, Drug
Enforcement Bureau, Phoenix Police
Department. “The ability to shut down public Wi-
Fi access or other non-essential communications
in case of a major incident or other emergency,
and redirect all bandwidth to mission critical
communications, gives us peace of mind if we are
asked to share our wireless infrastructure.”
Wireless video surveillance over the licensed
4.9 GHz public safety band is growing exponen-
tially in the US, with significant deployments in
Chicago, Dallas, Boston, Phoenix and West Palm
Beach, Fla., among others. Most public safety
agencies in the US already own a 4.9 GHz license
and plan to use it for access. Wi-Fi access allows
patrolling officers to tap into the video surveil-
lance network to monitor live video feeds as they
respond to incidents.

Wireless access deployments in a public safety setting
enable high-bandwidth communications, such as 20
Mbps wireless offload of recorded in-car video over a
secure connection, alleviating the need to manually plug
and unplug digital video recorders during patrol shift
changes. In contrast, a cellular data adapter delivers a
maximum of 1 Mbps throughput.
The benefits of the new tri-band functionality extend
to industrial and commercial security customers as well,
as they now have the flexibility to select between 2.4 and
5 GHz access for optimal network performance.
Firetide’s end-to-end management and control allow net-
work managers to provide varied levels of service by
type of traffic, video, VoIP or data, and by type of client
device, video camera, laptop or access control
system. Firetide also delivers enterprise-class
access functionality, bringing network security,
management and scalability to outdoor public
safety settings. These features include client
authentication and accounting, multiple virtual
access points, load balancing, VLAN tagging and
rogue device detection.

AirWalk Introduces the EdgePoint Femtocell
AirWalk Communications has introduced EdgePoint, a
femtocell that extends cellular service to areas of poor cel-
lular reception. The devices serve as low-power access
points, operating in licensed spectrum, to connect mobile
devices to the mobile carrier's network via the Internet.
By deploying the 7 by 7 by 2 inch femtocells at cus-
tomer sites, cellular carriers can reduce the customer
churn typically associated with poor reception. This
enables carriers to reduce their operating costs by using
existing home IP backhaul technologies for the
EdgePoint traffic, eliminating the pressure to build out
their networks in fringe areas.
EdgePoint is simple to use just plug directly into a DSL
or cable broadband connection. The femtocell is pro-
grammed for existing handsets computers. Users can
guarantee good reception, including smooth handoff of
calls originated on EdgePoint to the macro network, and
can work with their carriers to secure certain service
plans. The EdgePoint eliminates existing landline phones
and supports calls on one number, on one cellular service.
The EdgePoint architecture combines a base station
transceiver, base station controller, and network inter-
faces into a single unit and can be configured for either
1xEV-DO Rev. A or 1xRTT. With a range of about 250
feet, EdgePoint is well suited for single family home and
smaller office settings.

Günther Schlegel, Sr. RF Applications Engineer,EPCOS SAW
The number of RF based AMI (Advanced Metering
Infrastructure) systems being deployed is steadily
increasing. The RF front-ends of such AMI systems must
have very good sensitivity while proving to be immune
to any interference coming from different RF-based
applications. These interferences must neither hinder the
data transmission nor make it impossible to receive the
measured data. The figure below shows a typical trans-
ceiver design used in an RF based AMI systems.
The transmitter section of the AMI transceiver con-
sists of a balun which is transforming the differential sig-
nal coming from the RF output of the IC to a single ended
signal. After passing through the SPDT switch and the
PA, the RF modulated signal is filtered by a SAW filter.
This SAW filter suppresses the harmonics as well as the
spurious emission generated by the internal PLL (phase
locked loop) of the Transceiver IC. The antenna then
transmits the data to the meter.
The receiving path is where the trigger signal for data
transmission is being received. This consists of a SAW
filter right after the antenna, a second SAW filter for
increasing selectivity and the balun which transforms the
unbalanced signal into a balanced one.
SAW Filters vs. LC FilteringVery often, chip manufactures promote their ICs with
the statement “no SAW filter necessary”. When compared
to the suggested discrete filter solutions SAW filters show
many advantages with regards to technical parameters.
Even wide band SAW filters provide better selectivity and
insertion attenuation together with low temperature coef-
ficients. In the figure below, a comparison of an LC filter
to a wide band SAW filter is shown at 915 MHz.
High selectivity is important especially to suppress
interferences coming from other RF transmissions, such
as cellular radio for example, which is very close to the
most common ISM band used for meter reading trans-
ceivers, 902 to 928 MHz. The performance of LC filters
is very sensitive to component tolerances and to changes
in temperature. Designing a LC filter with the shown
selectivity also increases insertion attenuation. In the
above example, the LC filter has an insertion attenua-
tion3 dB worse than that of the SAW. Looking at fig. 1
it can be seen, that this front-end uses two SAW filters to
provide a better selectivity. The performance of this
structure can be seen in figure 3.
The disadvantage of this circuit topology is the
increased insertion attenuation due to the two SAW fil-
ters in series. Since the filters are located right after the
antenna, they directly influence the sensitivity of the
receiving chain. Measurements for sensitivity are the
noise factor and the noise figure of the system. The noise
factor describes the signal to noise ratio at the input of a
two port element relative to the signal to noise ratio at the
output of the two port device.
Where Si is the signal at input, Ni the
noise at input, SO the signal at output
and NO the noise at output of the two
port device. The noise factor is a
linear figure and can be converted
to the more common logarithmic
noise figure by using formula (2).
As an example the noise level at the input of a two port
device shall be -90dBm, signal level at input -40 dBm. At
the output of the two port device – assuming a gain of 20
dB and a noise figure of 2 dB - the noise level shall be at
-68 dBm and the signal level at -20 dBm. The unit dBm
in this case describes the RF- or noise power in dB rela-
tive to 1 mW (extended form: dBmW). For proving the
correctness of above formulas, the power levels are con-
verted to linear values.
Using the first formula, the noise factor can be calcu-
lated to F = 1.5849. Inserting F into the second formula,
the noise figure can be calculated to NF = 2 dB.
It can be seen, that for simple noise calculations with
only one two-port device there is no need to convert the
power levels to linear values. A simple addition of the
“dB” values does the same job.
For two or more two port devices cascaded like it is
done in figure 1, a more complex formula has to be used
and the power levels given in dB have to be converted to
linear values first. Formula (3) shows how to calculate
the noise factor when more than one two-port devices are
cascaded. The final noise figure NF1-n can be calculated
using formula (2) again.
Whereby Fn, Gn is the noise factor and gain of
the respective two port device.
Now it is fairly clear, that theoretically the most
important noise figure determining device in a
receiving chain is the first two port device right
after the antenna. The noise figure of that device
sets the range, where the total noise figure must be
located. An ideal circuit topology will have a low
noise figure and high selectivity. The following 4
examples examine how to develop such a topology.
For simplicity reasons the calculations are
done without Tx/Rx switches and baluns. The
insertion attenuation (IA) of the SAW filters; the
gain (G), noise figure (NF) and the noise factors
(F) of the LNA, and the receiver IC are all
assumed to be equal for all examples.
The gain of a SAW filter is supposed to be
equal to its insertion attenuation. The noise figure
of a SAW filter is supposed to be the negative
value of its IA.

FeatureNETWORKING
June/July 2008 Remote Site & Equipment Management 27www.RemoteMagazine.com
Since the gain of the
SAW is negative the
noise figure of the
receiver IC has a big
impact on the noise
added to the incoming
signal. This means the
noise floor increases by
more than 10 dB, or, the
signal to noise ratio is
decreased by 10.9 dB.
This in turn reduces sen-
sitivity of the receiver.
The advantage of this
structure is the blocking
of interfering signals out of band of the SAW which
in turn protects the internal LNA of the Rx IC from
being put into saturation. To reduce the noise figure
drastically a stage with a high gain and a low noise
figure has to be put in front of the SAW. The next
example shows a structure with a much lower NF.
By choosing this kind of front end structure the
NF can be reduced by more than 8 dB compared
to the former SAW – Rx IC structure. The LNA
with its high gain and very low noise figure is
now the first stage after the antenna and reduces
the impact of the SAW and the Receiver IC to the
NF. A further advantage of the SAW in this exam-
ple is to increase selectivity. The SAW is con-
nected differentially to the input of the Rx IC.
Since most of the Rx chips provide a balanced
(differential) input, the SAW filter can also be
designed with balanced output, providing the
matching function, and eliminating the need for a
balun. Common mode rejection ratio and selec-
tivity can be increased by using this topology.
The challenge with this topology is that the
receiver is more sensitive to strong interfering
signals; like cellular radio for example.
Often AMI sensors are equipped with an addi-
tional cellular radio functionality to transmit con-
sumer data to, for example, an interrogating base
station. During cellular transmission the strong
signal can be applied to the input of the LNA right
after the antenna by electromagnetic coupling or
other parasitic coupling on the pcb. This strong
signal may put the LNA into saturation and make
the receiver blind for the consumer data sent by a
different sensor in a mesh network. At the end this
data will not be received. To avoid this, a front-
end structure can be used as shown in example #3.
Example 3 shows a topology providing a compro-
mise between lower noise figure and improved
immunity to interfering signals. Here a noise figure of
4.88 dB can be achieved, which is still much lower
than the first approach in example #1. The SAW fil-
ter right after the antenna protects the LNA and
reduces the probability of the LNA being put into sat-
uration. Depending on how close the interfering sig-
nal is located to the passband of the SAW filter, the
possibility of the usage of a second SAW in front of
the LNA shall be taken into consideration. This improves
selectivity and reduces the interfering signal as can be seen in
figure 3. NF will be then be reduced to ~6dB, which is much
better than 10.9dB. Since discrete LNAs provide a single
ended output, a balanced matching structure between the
LNA and Rx IC is necessary.
Example #4 shows a
final topology which
optimizes the use of
SAW filters for maxi-
mum selectivity and
sensitivity in a receiv-
er front-end stage.
This extended version of a receiver front-end provides
a noise figure of 5.37 dB. Compared to example #1 it
means that this Rx front-end including the internal LNA
of the Rx IC, adds 5.53 dB less noise power to the noise
floor present at the antenna input. Considering that 3dB
less means half the power and 6dB less a fourth of the
power, it gives a good impression about the advantages
of this kind of front-end topology.
An improved sensitivity and selectivity together with
the advantage of improved common mode rejection
through balanced operation of the second SAW filter char-
acterizes this configuration. Therefore it is presented here
as the most suitable topology for RF based AMI systems.

20 kW Generator Features Built-InTransfer Switch
Power outages due to severe weather or rolling black-
outs are becoming more prevalent. For wireless providers
and users the outages
pose numerous risks,
the most important
being the inability to
communicate. A solu-
tion for ensuring wire-
less sites continue
operating when severe
weather or rolling
blackouts strike is to
install a standby power
generator that automatically restores power when utility
power is unavailable.
To help these problems Generac Power Systems, Inc.
is now offering a 20-kilowatt generator with a unit-
mounted transfer switch, named the model 4920 that
saves time, space and money for wireless companies.
Because the transfer switch is mounted inside and pre-
wired to the generator, money is saved because installa-
tion costs are typically lower and no additional space (on
a pedestal or building) is required to mount an external
transfer switch.
“For wireless carriers that are deploying back-up
power in quantity, the 4920 model is an amazingly
affordable alternative to gaseous powered fuel cells,”
said Clement Feng, executive vice president and chief
marketing officer, Generac “At around $7,000 per gener-
ator (switch included) a carrier can back-up 10 sites for
about the same cost as only one fuel cell of the same
power rating.”
The generator runs on clean burning fuel, either natu-
ral gas or liquid propane (LP) vapor, so there are none of
the fuel storage, spillage, spoilage or odor concerns that
are common with gasoline or diesel models. Because of
their favorable emissions profile, gaseous-fueled genera-
tors are becoming increasingly popular with wireless
companies as a “green” solution for backup power needs.
A tough, textured powder coat finish that provides
durability and all weather protection is used on these
units. They also come equipped with an all-aluminum
enclosure to better withstand the elements in highly cor-
rosive environments.
EnerSys Releases DataSafe 16 VFront-Terminal UPS Batteries
EnerSys has introduced the first 16 V front termi-
nal battery for UPS markets. The DataSafe 16 V bat-
tery provides more power in less space, easier access
and cost benefits.
"EnerSys is proud to introduce the first 16 V
front terminated
va lve- regula ted
lead acid (VRLA)
battery designed
specifically for
UPS applica-
tions," said Steve
Vechy, director of
UPS and Utility
Marketing, EnerSys. This is also a major step
forward for our entire industry in supporting
UPS applications."
The DataSafe 16 V UPS battery is available in
two sizes: 500 W per cell (WPC) and 925 WPC.
The DataSafe 16 V batteries require only 44
square feet to support a typical 750 kVA UPS sys-
tem with a full 15 minutes of run time. The VRLA
batteries used for UPS applications are designed
to back-up the primary power system, typically
supplying power for 15 minutes until the backup
generator is fully operational. Until now, these
batteries were limited to 12 V batteries.
DataSafe UPS batteries require 20 percent less
space and scale easily to large capacity systems,
minimizing the number of strings needed for larger
UPS systems thereby reducing costs. The DataSafe
16 V battery fits within many existing cabinet
designs, eliminating additional expenses for costly
slide-out trays or to upgrade from 12 V batteries.
By using a popcorn-ball design, tiny kernels clumped into much larger porous spheres,
researchers at the University of Washington are able to manipulate light and more than
double the efficiency of converting solar energy to electricity.
"We think this can lead to a significant breakthrough in
dye-sensitized solar cells," said lead author Guozhong
Cao, a UW professor of materials science and engineering.
Dye-sensitized solar cells, first popularized in a scien-
tific article in 1991, are more flexible, easier to manufac-
ture and cheaper than existing solar technologies.
Researchers have tried various rough surfaces and
achieved higher and higher efficiencies. Current lab pro-
totypes can convert just over one tenth of the incoming
sun's energy into electricity. This is about half as efficient
as the commercial, silicon-based cells used in rooftop pan-
els and calculators.
The UW researchers did not attempt to maximize the
overall efficiency of a dye-sensitized solar cell to match
or beat these previous records. Instead, they focused on
developing new approaches and compared the performance of a homogeneous
rough surface with a clumping design. One of the main quandaries in making an
efficient solar cell is the size of the grains. Smaller grains have bigger surface area
per volume, and thus absorb more rays. But bigger clumps, closer to the wave-
length of visible light, cause light to ricochet within the thin light-absorbing sur-
face so it has a higher chance of being absorbed.
Other researchers have tried mixing larger grains in with the small particles to scat-
ter the light, but have little success in boosting efficiency.
The UW group instead made only very tiny grains, about
15 nanometers across. Then they clumped these into larg-
er agglomerations, about 300 nanometers across. The larg-
er balls scatter incoming rays and force light to travel a
longer distance within the solar cell. The balls' complex
internal structure, meanwhile, creates a surface area of
about 1,000 square feet for each gram of material. This
internal surface is coated with a dye that captures the light.
The researchers expected some improvement in the
performance but what they saw exceeded their hopes.
The overall efficiency was 2.4 percent using only small
particles, which is the highest efficiency achieved for this
material. With the popcorn-ball design, results presented
today at the conference show an efficiency of 6.2 percent,
more than double the previous performance.
"We first wanted to prove the concept in an easier material. Now we are working
on transferring this concept to titanium oxide," said Cao. “Titanium oxide based dye-
sensitized solar cells are now at 11 percent maximum efficiency. Cao hopes his strat-
egy could push dye-sensitized solar cells' efficiency significantly over that threshold.”

Tripp Lite Releases Modular 3-Phase UPS SystemsConfigurable up to 160 kVA
Tripp Lite has introduced a
new line of SmartOnline
Modular 3-Phase UPS Systems
for 120/208 V applications.
Three models are available
(SU40K, SU60K and SU80K)
with individual capacities rang-
ing from 40 kVA to 80 kVA,
system capacities up to 160
KVA and operational efficien-

reliable installation and econom-
ical operation and maintenance,” said Paul
Wampach, Tripp Lite's 3-Phase UPS System
product manager. "They maximize availability
for mission-critical systems, lower installation
and operational costs, while facilitating efficient
and timely service performance. The modular
architecture and 1+1 parallel capability will fit
well in countless organizations, even those pur-
suing tier 4 system availability.”
Tripp Lite's new UPS Systems feature self-
contained, hot-swappable 20 kVA power mod-
ules. SU40K, SU60K and SU80K models feature
multiple modules to provide N+1 redundancy for
critical loads. In the unlikely event that a module
fails, the remaining modules compensate to sup-
port the load. The new models also feature 1+1
parallel capability, enabling two units connected
in parallel to either provide 2N system redundan-
cy or increased power capacity.
In a parallel redundant configuration, each
UPS supports 50 percent of the load. If one UPS
is subsequently removed or taken off line for
maintenance, the second UPS will support the full
load automatically. Parallel connection can also
be employed to double overall capacity.
Therefore, two 80 kVA units can be connected in
parallel to support a load of 160 kVA.
The SmartOnline Modular 3-Phase UPS
Systems also help facility managers to control
installation and operating costs. Producing less than 3 per-
cent input Total Harmonic Distortion (THDi), they enable
a 1:1 sizing of the UPS system to a generator set. Low
THDi helps generators to run cooler, lengthening genera-
tor service life, and eliminating the need to oversize gen-
erators, cables and breakers. Advanced IGBT inverter
technology assures high-efficiency UPS operation, reduc-
ing cooling costs and lengthening UPS service life.

Lumenera Releases Two NewIntelligent Megapixel Cameras
Lumenera Corp. has released two new intelligent
camera models that respond to security threats in real-
time. The Li165 and Li175 provide unique, tangible
results by preventing intrusions, attacks and vandalism
while in progress.
The Li165 is specifically designed for critical surveil-
lance applications with low-light conditions and/or fast
motion where the ultimate in megapixel image quality is
required. Streaming full 1,376 by 1,032 megapixel reso-
lution at up to 15 frames per second, the Li165 transmits
high quality MJPEG or H.264 images across a standard
10/100BaseT network interface. The Li165 combines
added sensitivity and extremely low noise levels for per-
formance in poor lighting conditions. The high-end glob-
al shutter CCD is well suited for capturing images of rap-
idly moving vehicles.
The Li175 combines 1.3 megapixel image quality
with video analytics to help automate surveillance in
any environment. A CMOS sensor provides images at
up to 21 frames per second. This camera has powerful
peak white inversion and anti-blooming features for
dealing with intense glare from reflected sunlight or
headlamps on vehicles.
Features such as Power Over Ethernet (PoE), analog
loop-out, advanced dc-iris control and improved software
interface are standard. Cameras are future proofed with
on-going software developments and analytic enhance-
ments that are remotely upgradable via the IP Network.
Integration with NVRs/DVRs is simplified with

Arteco has recently installed an intelligent video solution (IVS) for the Louisville
Water Treatment Plant, in Louisville, Ohio. Among the most significant problems
water facilities face in the prevention of water contamina-
tion is security. Due to the tough environmental elements
and because these facilities are located remotely where
intrusion is hard to detect, water treatment plants often
present a major challenge to basic video security.
The Louisville Water Treatment Plant is owned and
maintained by the city of Louisville, the utility provides
water resources to more than 3,300 households and busi-
nesses in the community. With a constant goal to provide
a safe and dependable supply of drinking water, The
Louisville Water Treatment Plant recently turned to
Zadar Technology, Inc. and Arteco to proactively combat
water contamination.
“Water facilities present a high security risk to contam-
ination due to outdoor open access, this risk can be mini-
mized by implementing appropriate protective measures,” said Ken Zadar president,
Zadar Technology, Inc. “Intelligent Video offers a proactive and cost-effective solu-
tion to water utilities, giving a higher security guarantee for their public service.”
To solve the treatment plants problems, Arteco mounted an outreach program that
educates executives in these facilities about the unique aspects of video analytics that
provide a practical, efficient resolution. The Arteco IVS
detect and alerts in real-time, helping to increase the effi-
ciency and response rate of personnel who are responsible
for a multi-camera site.
Utilities will typically set up virtual perimeters around the
fence of the water treatment plant. Should a dog wander into
this perimeter or trash be blown in it, the system holds
steady. But if a man approaches the gate of the tank the sys-
tem detects the size and orientation immediately and triggers
an event within the IVS. At the utility control center, an alert
sounds and a red box appears on a video monitor that draws
attention to the violated area. Security then uses this infor-
mation to take the appropriate countermeasure.
“Through our work with great partners like Zadar
Technology, Inc., many new customers are understanding
the true benefits of Intelligent Video,” said Steve Birkmeier, vice president, Arteco.
“The real-time alert capability adds a pro-active layer to security with built in video-
verification that is unique to any product in the industry.”

Yokogawa Selects Tofino asIts First Approved IndustrialFirewall Solution
The Tofino Industrial Security Solution has
been selected by Yokogawa Electric Corp. as the
first industrial firewall,
giving Yokogawa’s
Centum CS 3000 pro-
duction control system
and Stardom network-
based control system
customers access to
this new security tech-
nology. Jointly devel-
oped and marketed by
MTL Instruments and Byres Security, Inc., the
Tofino Industrial Security Solution is designed
specifically for industrial control operations in
critical industries such as oil and gas, manufac-
turing, utilities and power generation.
Tofino’s are small, industrially-hardened secu-
rity appliances that are deployed throughout a
refinery or industrial plant and centrally managed
for a coordinated security approach. Each Tofino
security appliance is placed in front of one or
more mission-critical control devices, such as the
Stardom industrial controller as well as the sub-
system interfaces of CS 3000 which run the open
industrial protocols, and then tuned to meet the
security requirements of those systems.
The approval of the Tofino Industrial Security
Solution will give Yokogawa’s SCADA and
process control equipment customers the much
needed ability to deploy Defence-in-Depth secu-
rity in their industrial systems. The solution pro-
vides multi-layer security, and the approval came
after months of extensive testing and analysis of
the Tofino Industrial Security Solution by the
industrial automation and control giant.
“The Yokogawa testing process is extremely
rigorous,” said Byres security development
manager, Scott Howard. “I was very impressed
with the competence and level of focus dis-
played by the Yokogawa team – nothing went
unnoticed or untested.”
“If companies want to meet the new
ANSI/ISA-99 security standards it is critical they
divide up their plant operations into security
zones and then protect each zone in the most
appropriate manner, said Eric Byres, security
expert and CTO, Byres Security, Inc. “It is no
longer good security practice or cost effective just
to lump everything together behind one big fire-
wall and pray that you are secure.”
The Tofino Industrial Security Solution is
unique in the industry, designed by control engi-
neers for control engineers, so that they can focus
on keeping a system reliable yet secure, thus
meeting or exceeding all the available standards
and regulations.
Industrial Video & Control ExpandsRapid-Deploy Camera Line
Industrial Video &
Control Co. (IVC), has
released its RD line of rapid-
deploy camera systems.
“The cellular camera we
introduced last year has
been extremely successful
for certain temporary or
remote video surveillance
needs,” said Norman Fast,
president, IVC. “We are now
expanding our line of rapid-
deployment cameras to incorporate a variety of commu-
nication and mounting options. This will provide our cus-
tomers a broader range of capability options.”
The systems are engineered for easy transport and set
up. They include IVC’s Relay Server and View Station
enterprise-class video management software packages.
This software facilitates remote viewing and control of
live and stored video from the rapid-deployment cam-
eras, and easy integration with wired and legacy cam-
eras. As the video is IP-based, customers can easily
share video with other stakeholders. For instance, if a
university deploys such a system on campus to monitor
a unique event, campus police can easily share video
with local authorities.

Wireless mesh networks have undergone much aca-
demic research over the past twenty years. The Defense
Advanced Research Projects Agency (DARPA) funded
research of mesh networks because of their inherent reli-
ability and flexibility, in the hope of applying them to
military applications. Mobile and nomadic communica-
tion in the battlefield or in hostile environments was the
original optimum application of mesh networks.
The absence of any single point of failure makes mesh
architecture the ideal network topology where many-to-
many communications are possible but one doesn’t want
to rely on layered and stellar architecture. Every node is
a peer node in a mesh network, and there is no higher
layer or controlling node that can be destroyed to bring
down the entire network. The unmatched reliability and
flexibility that a mesh-capable transmitter offers, com-
pared to traditional wireless devices, are making wireless
mesh the preferred network architecture for high-end
wireless video-surveillance, condition-monitoring and
wireless SCADA systems.
Self-Forming and Self-Healing Mesh NetworksNodes in a wire-
less mesh network
are powerful
devices that run
advanced mesh
routing algorithms
designed to evaluate
and select the opti-
mal path for every
transmitted packet
in real time. The
dynamic mesh rout-
ing algorithm allows
the routing of packets and video streams around obsta-
cles, sources of interference or low-quality links, increas-
ing reliability and flexibility at the same time.
Wireless mesh devices are completely auto-config-
urable, the routing protocol finds other mesh devices
nearby and the location of the base units attached to the
wired network. If a link goes down, the nodes in the net-
work will immediately notice the failure and change their
preferred path to avoid the failed link.
Routing of Packets in a Wireless Mesh NetworkRouting in a wireless environment is conceptually
similar to routing over the Internet, but is different in
terms of evaluating the quality of a particular path. While
Internet routing is based on minimal hop count, the qual-
ity of wireless links in a mesh network is crucially impor-
tant. Researchers at the Massachusetts Institute of
Technology (MIT) recently discovered that minimum
hop count is not effective for wireless routing. Rather, a
metric involving link-quality measurement is needed to
create reliable wireless mesh networks. This discovery
broke most of the layered abstractions developed by the
“inventors” of the Internet in the 80’s and 90’s and estab-
lished new ways of thinking about wireless routing.
It’s easy to see the importance of link quality in a wire-
less environment. Wireless links tend to have high pack-
et-loss rate and the transmitter needs to resend the lost
packets multiple times, wasting valuable bandwidth.
Consequently, it’s often preferable in a mesh network to
take a longer yet
more reliable path
rather than the
unreliable direct
route to the end
point. Often the
shortest path
would require
multiple retrans-
missions per pack-
et, wasting band-
width and increas-
ing delays.
By continuously probing the different wireless links,
every mesh node builds and updates statistics regarding
every link available. These link-quality tables are then
used by the routing protocol to compare every possible
path and pick the optimal one at any given time.
Origin of Wireless Mesh Networks and Their Traditional Uses
Many defense-related applications of mesh networks
involved highly mobile and battery-powered units, cre-
ating challenging technical problems whose solutions
are still in their infancy. However, mesh networks for
data transmission, video-streaming or temporary com-
munications in case of natural disasters are a reality
today, with several different products focused on differ-
ent types of applications.
Challenges in Streaming Video Over Wireless Mesh Networks
Video-streaming and video-surveillance have been one
of the latest additions to the list of possible applications
for mesh technology. However, high-resolution video-
streaming over a mesh network presents several technical
challenges: bandwidth is always scarce when dealing with
high resolution video and a multi-hop transmission may
decrease usable bandwidth and increase delay. For exam-
ple, a video packet that goes through three hops absorbs
three times the bandwidth compared to a video packet that
is only one hop away from its destination.
Advanced mesh products solve these challenges by
operating multiple radios simultaneously. In this way, the
video stream can use many different channels to create
high-bandwidth and low-delay paths. Operating multiple
radios increases the bandwidth by spreading the trans-
missions on multiple non-overlapping channels while
decreasing the delay of the network. At every hop the
packets go through, the mesh transmitter can choose the
best frequency to reach the following node, therefore
optimizing not only the path but the frequency spectrum
usage, as well.
Routing in a multi-hop, multi-radio mesh net-
work requires, however, advanced routing algo-
rithms and powerful processors embedded in the
transmitter. The optimization work is computa-
tionally expensive and the processor needs to
continuously crunch and solve complex opti-
mization problems in real time.
Wireless Mesh Networks:Traditional Uses and Video-Surveillance Applications
Wireless mesh and video surveillance usedin an urban environment. In a wireless mesh network, the shortest path
may have a low success probability (30 per-cent success rate) than a longer path (90 per-cent/90 percent/80 percent = 65 percentsuccess rate).
In a single-radio mesh network, adding a hop decreases thetotal available bandwidth by half because every packetsneeds to be transmitted twice.

Advantages of Using Wireless Mesh Networks forVideo-Surveillance Applications
Mesh architecture is the solution to several problems
faced by security system integrators when they work on
wireless video-surveillance systems. Mesh devices are
completely auto-configurable and capable of deciding
how to transmit packets based on the present conditions
of the channels rather than on pre-determined configura-
tion values.
Reliability and flexibility are intrinsic benefits of mesh
architecture. Unpredictable sources of interference do not
need to be anticipated as the network will identify the
position of the source of interference and start routing
packets around low-quality links. Airports and seaports
are typical locations where mesh architecture solves sev-
eral problems at once.
Airplanes taxiing on the ground are often unpre-
dictable and moveable sources of interference. During
the design and the installation of a mesh-based CCTV
system, it’s not necessary to identify every possible posi-
tion where an airplane can be interfering in the video
streaming quality. The mesh network itself will find alter-
native paths in case some of the links are not usable due
to interference. Similarly, using traditional wireless tech-
nology in commercial seaports is also very challenging
because loaded container ships are almost moving build-
ings, making the design of a traditional static wireless
network almost impossible. However, using a mesh-
based architecture, video-streams will change their path
in case a container ship docks in the middle of a wireless
link impeding transmission through that particular path.
The transmitter will always have an alternative to reach
the base station.
Using traditional point-to-point solutions large obsta-
cle like hills, buildings or forests require the installation
of high towers or poles to create line-of-sight between the
antennas. Video-streams don’t have to overcome these
obstacles when taking a mesh-based approach but can
simply be routed around them. Line-of-sight is not
required from the camera directly to the base station, it’s
only needed for the next node in the mesh network that
will then relay the stream to the following one and so on
until the packets reach the base station.
Automatic Solution for Exogenous InterferencesLarge industrial areas are often characterized by a high
density of RF devices, and the problems related to
exogenous interferences deriving from other
transmitters are rather frequent.
The types of interferences that may occur
are due mainly to:
• Other transmitters operating on frequencies
close to or coinciding with those used (e.g.,
Wi-Fi networks, Hiperlan data networks, and
analog radio links for various purposes
including video-security);
• Different devices whose operation creates
interferences in the bands affected by the tran-
smission (e.g., radars or microwave ovens).
Conversely, low-frequency (UHF, VHF) radio
equipment or cellular towers are not sources of
interference for most 2.4 GHz and 5 GHz radio
equipment. Only extreme physical proximity of
the antennas could result in reduced transmis-
sion performance.
Interference is one of the most complex phe-
nomena that need to be tackled in the area of radio
transmission. It must be addressed simultaneous-
ly at different levels using the least busy channels,
while also introducing redundancy into the sys-
tem so that it can assist with automatic adjustment
in case of unexpected interferences.
During preliminary inspections and installation,
it‘s important to be able to evaluate any possible interfer-
ences caused by other wireless networks existing in the
area. (A Wi-Fi device in listening mode or a spectrum ana-
lyzer may be used to identify them.) It’s also always
advisable to ask the customer about the existence of other
radio devices in the area, their carrying frequency, their
bandwidth and power. Careful planning can solve a large
percentage of problems relative to interferences.
When operating on license-free bands, keep in mind
that the absence of a wireless network on the day of test-
ing doesn’t mean that one cannot be installed in the near
future. Consequently, it’s important to introduce redun-
dancy into the network and use dynamic equipment that’s
able to identify new interferences and respond to mini-
mize their effects. This approach usually requires the use
of smart radio equipment, often of the mesh type, set to
perform constant transmission channel analysis and to
select in real time the best pathway within the network
and/or channel most free of interference.
ConclusionMesh topology is undoubtedly a step forward in wire-
less networking applied to video-surveillance applica-
tions. Reliability and flexibility unmatched by any other
wireless solution are intrinsic in this innovative architec-
ture, where every node in the network is an “intelligent”
router capable of forwarding packets received from near-
by units and deciding in real time the optimal path based
on the channel and network conditions.
Mesh networks also enable the installation of wireless
CCTV and SCADA systems where other wireless solu-
tions fail, such as in the presence of moveable obstacles
or sources of interference. Mesh networks are also allow-
ing the design and installation of condition-monitoring
and security systems with the reliability of a wired net-
work but a higher flexibility than any point-to-point or
point-to-multipoint wireless system.

Kyocera Wireless and M2MCommunications Collaborate onLoad Control System
Kyocera Wireless Corp. and M2M Communications
have announced the successful deployment of a sophisti-
cated direct load-control program custom engineered for
Rocky Mountain Power’s demand-side management
project. M2M Communications integrated a NetSwitch
load-control solution and the dual-mode Kyocera 200
module along with its custom-designed Web-to-wireless
control system to enable a versatile and secure method to
remotely monitor and control energy usage at irrigation
pump sites. Over the next 18 months, 4,000 of these cus-
tom-designed load control units will be installed in
southeast Idaho, allowing Rocky Mountain Power to
shift enough energy from irrigation pumps to power
approximately 8,000 homes during the summer months.
“There is a renewed global focus on energy conserva-
tion and the environment. Utility demand-side manage-
ment projects powered by wireless M2M technology
benefit not only the companies implementing the tech-
nology but the environment as well,” said Dean
Fledderjohn, general manager of M2M, Kyocera
Wireless Corp. “This collaborative, custom-built solution
leverages the dual-mode capability and power of the
Kyocera 200 module for a remote monitoring and energy
asset control system that makes the most of existing util-
ity power supplies without requiring additional energy
generation or pollution.”
During the summer months, as much as one-third of
the total power consumption in rural areas is devoted to
irrigation pumps and systems. Direct load control pro-
grams give utility companies the ability to reschedule the
power consumption for various types of equipment at par-
ticipating customer sites during times of peak energy
demand. With the custom-designed load control units in
place, utility companies can monitor power usage remote-
ly as it is being consumed and determine in real-time if
the available power supply is being optimized. If not, util-
ity technicians can use the system’s two-way Web-to-
wireless control system to shift power to other areas.
The system’s controls also provide automated, time-
scheduled monitoring and load management, which
results in decreased technician time spent on monitoring.
As a result of the program, farmers receive credits for
unused power while Rocky Mountain Power increases
workforce efficiency and reduces overall costs. In addi-
tion, the system eliminates the need to purchase expen-
sive peak-load power from other utility companies and
can even reduce the need to build additional expensive
power plants.

Lake Country Power of Grand Rapids, Minn., has suc-
cessfully deployed a full two-way automated metering
infrastructure (AMI) to its entire service territory cover-
ing more than 10,000 square miles in northern
Minnesota. The Cannon AMI system by Cooper Power
Systems gives Lake Country the ability to read meters on

plaints, decrease issue resolution time, verify outages and
restoration real time and monitor substation equipment.
"We wanted a system that could be installed in all 39
of our substations, with the capability to handle more
than 60,000 meter reads and remotely monitor our sub-
station equipment," said Rick Lemonds, general manag-
er, Lake Country Power. "Our AMI system has already
made positive service impacts, by providing the
right employees with the right information when
requested. This provides our members with data
to support answers to their questions."
Lake Country Power has noticed time savings
in solving customer issues through the ability to
profile energy use and remotely read meters from
the office. In the past they would send a techni-
cian on site to check on most high bill issues.
Now Lake County Power handles many of these
directly from the office, greatly reducing time and
expense to resolve customer inquiries.
The AMI system successfully integrates with
Lake Country Power's existing billing and outage
management software allowing for the automatic
generation of monthly billing statements and ver-
ification of outage events and restoration. Lake
Country Power anticipates significant savings
using the system to verify load management com-
mands sent to its load control receivers.

Honeywell and the City ofHillsboro Power Water StorageFacility with Solar Panels
The city of Hillsboro, Ore. has awarded
Honeywell a solar project that is expected to cut
energy costs and greenhouse gas emissions.
Under the agreement, Honeywell will install
ground-mounted solar panels next to the Hillsboro
Evergreen Reservoir water storage facility and
sell the electricity the panels produce to the city
for use at the reservoir. The panels are expected to
generate more than 104,000 kw-hours of electric-
ity annually, almost 20 percent of the power need-
ed for the 15 million-gallon Evergreen Reservoir.
Energy Trust of Oregon, a nonprofit organiza-
tion that promotes the use of efficient energy
technologies and renewable resources, will help
fund part of the project. Honeywell also will
work with Renewable NRG, an Energy Trust
Trade Ally based in Portland, Ore., to install the
solar panels. SolarWorld Group will supply the
solar modules and installation hardware.
The project will deliver environmental bene-
fits as well, cutting carbon dioxide emissions by
an estimated 3.6 million pounds over the 20-year

Worldwide Study of Electric PowerSCADA and Energy ManagementSystems Now Underway
The Newton-Ev¬ans Research Company has formally
commenced its 10th study of global trends and plans for
electric power operational control systems, impacted
today by a barrage of new legislation, compliance require-
ments, smart grid developments and information security
concerns. The 2008 study will include findings from more
than 200 North American power utilities and 100-plus
international utilities from 50 or more countries.
This international study of mission critical, real-time
electric utility operational systems including energy
management, supervisory contro, and distribution net-
work management will result in the publication of four
volumes of research and planning information of impor-
tance to utilities, systems integrators and participants in
smart grid developments.
Highlights from preliminary findings and observa-
tions from Newton-Evans’ multi-month study of trans-
mission and distribution monitoring and control sys-
tems include close to a 20 percent increase in responses
(including six new countries) from the 2005 to 2007
study. Early highlights of the international 2008 study
of mission critical, real-time electric utility operational
systems including energy management, supervisory
control, and distribution network management include
outage management, power generation management,
linkages to external systems, external services required
and smart grid initiatives.
For outage management, about 40 percent of the inter-
national utilities surveyed so far this year have imple-
mented a separate outage management system (OMS).
This reflects an increase from 2005’s 30 percent of
responding utilities reporting having a separate OMS at
that time. Generation management systems (GMS) are
also experiencing an increased level of activity this year,
at least among the early international respondents. In the
2005 study, only a handful of participating international
utilities had reported use of, or plans for, a separate GMS.
The percentage this year has risen to 14 percent thus far
into the study.
Linkage to other utility enterprise systems continued
to be on the increase on a global scale despite cyber secu-
rity concerns. For many sites, the key to remaining
secure seems to be either: (a) the restricted provision of
non-real-time access via periodic downloads to author-
ized requestors or (b) indirect access to and from the con-
trol system via historian files.
The most frequently mentioned plans for additional
control system links this year from managers at interna-
tional control centers were reported as: Geographic
Information Systems (24 percent); enterprise application
integration (24 percent) and customer information sys-
tems (20 percent). The key linkages already in place
included historical record-keeping systems and files,
power plants, other utilities and an enterprise wide area
network. North American utilities were likely to be linked
up with these as well, but with a lower percentage of util-
ities involved than at their international counterparts.
By early 2008, about one-third of the international
respondents, and one half of the North American respon-
dents indicated a current need for one or more of the nine
listed “services” that could be available from external
service providers. More than one third of North
American respondents now require training services, fol-
lowed by “long-term maintenance agreements.” Among
international utility officials, commissioning and testing
of new systems was in demand. Installation support and
maintenance agreements followed. By 2010, utilities
around the world plan to bring in outside help to conduct
vulnerability assessments.
Just as there are important variances with regard to
communications protocols, control systems supplier
rankings, and new product development objectives
within the global electric power community, so too are
there differences in priorities for focusing on “smart
grid” initiatives. International utilities are placing more
emphasis at this time on automating the distribution
network and upgrading their control systems, while
North American utilities are more likely to emphasize
automated metering infrastructure as the priority task
for enabling the smart grid.

East Gippsland AdoptsMultiSmart
East Gippsland Water provides water and waste-
water services for the communities of East
Gippsland, Australia. This is a large area, 21,000
square kilometres in the far south east corner of
Victoria, from Bairnsdale to Dinner Plain in the
north and Mallacoota in the eastern tip of Victoria.
Around mid-2006 East Gippsland was looking for
equipment for flow monitoring and data logging to
assist with sewer modeling when the MultiSmart
pump station manager was demonstrated to them.
The MultiSmart did a lot more than these two func-
tions but was still cost-effective for the original
requirement so the authority purchased five units
and installed them over a period of a few months.
Frank McShane, the manager of operations, had
been using another pump controller, but after
reviewing the capabilities of MultiSmart found
that its capabilities were much more extensive.
Some areas which stood out were the phase to
phase voltage monitoring and datalogging, the
ease of use through the configuration menus and
the cellular data capability with DNP3. DNP3 is an
open protocol designed for remote telemetry, and
cellular data was a necessity because of the high cost of
building a radio network over such a large area.
MultiSmart also enabled East Gippsland to standard-
ize across all of their pump stations and eliminate the
need for PLC programming in pump stations. This pro-
vides an operational benefit and reduces costs. As a result
of the success of the initial installation, East Gippsland is
now converting another 20 stations over to MultiSmart,
and planning to convert all of the remaining wastewater
pump stations as fast as possible.
MsMUG Moves Working Group toThe Automation Federation
The Microsoft Manufacturing User Group (MsMUG),
formerly a part of OMAC, is moving to a working group
under the Automation Federation (a Remote 2008
Organization Sponsor) so that the group can better sup-
port the needs of the industry as a horizontal thread
across disciplines.
MsMUG was formed in 1999 to address issues that
arise when applying Microsoft technology in manufac-
turing. The mission of the group is to define and resolve
issues such as version management, system integration,
maintenance and supplier responsibility. MsMUG works
to develop a set of best practices that will aid in the use
of Microsoft operating systems in manufacturing envi-
ronment; provide input to Microsoft on the special needs
of this environment; encourage and influence software
suppliers to support these best practices; and provide
user input to the OPC Foundation on changes and
improvements to OPC.
"MsMUG creates an environment where end-users,
ISV's, integrators, and Microsoft can collaborate to share
information and solve problems," said Erik Goode,
MsMUG Chair with Cargill. "End-users and integrators
join to have an opportunity to be part of one manufacturing
voice. By moving the working group under the Automation
Federation, manufacturers in process, hybrid and discrete
manufacturing will all be part of that conversation."
There are three subgroups under MsMUG.
MUGSecure is focused on increasing Windows operat-
ing system reliability and security . MUGPatch concen-
trates on best practices for upgrade validation with OS
patches, and MUGOPC concentrates on the expanding
need to update user issues into OPC standards.

PCB Piezotronics Releases New Capabilities BrochurePCB Piezotronics (PCB) has released a four-
page, full-color capabilities brochure, entitled,
“Intrinsically Safe, Industrial Dynamic ICP
Pressure Sensors. The brochure highlights spe-
cific sensor and instrumentation available for
pressure monitoring, diagnostics, troubleshoot-
ing and control applications in hazardous fac-
tory environments, as well as oil, gas and
petrochemical, gas turbines, pumps and engine
and compressor monitoring applications.
PCB series 102A and 121A sensors offer
intrinsic safety certifications to CSA and
ATEX standards, permitting use on machinery
operating in hazardous environments.
Applications include monitoring dynamic pressure events such as surges, pulsa-
tions, spikes, leak detection, combustor instability and acoustics found in operation
of oil and gas well heads, pumps, gas compressors, pipe-lines, reciprocating
engines, and gas turbines.
Sensors may be used with ICP signal conditioning and permit use of a variety of
inexpensive two-wire cable systems. The low-impedance signal may be transmit-
ted over long cable distances, and sensors may be used in dirty environments with
no signal degradation. PCB can also assist with providing many other styles of
dynamic pressure sensors with hazardous area approvals.
ISA Releases Third Edition of Wireless Networks Resource
ISA has released the third edition of its popular book, Wireless Networks for
Industrial Automation by Dick Caro.
Available in digital format, this book includes the increasingly popular wireless
application Radio Frequency Identification (RFID) topic and also provides a clear,
unbiased view of the emerging wireless communications market. Caro's goal is to help
keep readers up-to-date with the wireless market so they can make better decisions on
the timing and strategy for implementing wireless networks for automation projects.
According to Caro, going wireless is more than just plugging in some wireless com-
ponents to replace the wires. Residential networks are easily justified using today's
inexpensive wireless components to avoid costly or unsightly wire installations.
Industrial use is not quite so clear due to privacy and security problems and the poten-
tial for signal loss in plant environments. Industrial use must have secure communica-
tions that never fails. However, the cost of industrial wiring is so high, that wireless can
usually be justified.
In this third edition, the author includes a general update of events that have occurred
since the previous edition. Of significance is an overview of new technology, such as
ISA100.11a, WirelessHART, and WiFi, including IEEE 802.11n.
