Modbus capable sensors and controllers from S+S save energy and costs

Driven by rapidly rising energy costs, there is a growing need for central acquisition,

monitoring and control of power consumption also in buildings. In the automated

“Smart Building” of the future, heating, venting, air-conditioning and further functions

are networked in a bus system that transmits their data to higher control and facility

management levels and vice versa provides for a downstream of control signals to

the devices on demand and on time.

This results in optimised energy efficiency and cost savings. Today, buildings still

account for approximately 40% of all the end-use energy consumed. At the same

time, consumption control regulations are being tightened, e.g. by means of

domestic Energy Performance Certificates introduced in line with European Directive

2010/31/EU.

Intelligent control technology can cut

power consumption by up to 70%.

Nearly 30% of the energy

used by companies is wasted.

Buildings account for approx. 40%

of all end-use energy consumed.

As a pioneer in bus capable sensors and controllers

for facility automation, S+S has long been offering

various THERMASGARD® and THERMASREG® tem-

perature sensors and controllers with Modbus RTU

connection. The portfolio is continuously being ex-

panded. Added devices also include first Modbus ca-

pable HYGRASGARD® humidity and PREMASGARD®

pressure sensors.

Innovation in technology and design

Like all control technology from S+S, these devices are

characterized by a consistent design with several innova-

tive features – such as our patented quick lock for ease of

assembly and splash-proof protection. All products are

manufactured in Germany to our acknowledged standards

of sensible precision and highest quality.

Available now: Sensors from S+S in new Tyr II design

Galvanic isolation

Bus cable and device are electrically isolated from each other to minimise interferences

A key advantage of all Modbus capable devices from S+S:

In housings of our Tyr I design, the display rests under a transparent cover in a bracket with an integrated film hinge to swing out.

MasterModbus

Rugged functional principleIn its specification for the non-proprietary Remote Terminal Units (RTU) com-

munications protocol, which is based on the master-slave principle, Modbus

has become one of the most widely used standards of facility automation.

Each device on the bus has a unique address. Commands are initiated by the

master (PLV or PC). The sensor or controller (slave) on the bus responds to

these commands by setting or changing functional parameters in its registers

and returning e.g. requested measured values, including its address so that

the master can allocate the response correctly. Address and function codes

each comprise 8 bits. By means of a cyclic redundancy check (CRC), a 16 bit

checksum is generated to ensure that commands arrive undamaged. Even

if several controllers or sensors should receive the same command, only the

one that has actually been addressed will act on it.

Modbus systems with sensors and controllers from S+S permit powerful as well as

cost-effective and sustainable solutions for an energy-efficient facility management:

✚ Energy savings through demand and time control of heating,

ventilation and air-conditioning

✚ Central acquisition, surveillance and optimisation of consumption data

✚ Remote monitoring and control intervention over mobile phone and internet

SUSTAINABLE BENEFITS

Thanks to its openness and simple implementation, Modbus meets with

increased acceptance as a bus system for building technology. Even complex

installations do not require much time and labour. Typical examples can be

found from industry to residential housing, including the wide segment of office

and public buildings.

More than 7 million Modbus nodes have been installed in Europe and

North America alone. The devices that “speak” Modbus RTU today are legion.

Hundreds of manufacturers are supporting the protocol.

Fast and simple implementation

Designed for clear views

The Modbus capable wall-mount

sensors from S+S are available

with a two-line display that is freely

configurable over the Modbus port

and provides measured readings on

site. Valid or faulty bus messages

are signalled by a green or red LED,

respectively.

Bus parameters and bus address are

set with DIP switches in the housing.

The display indicates changes for 30

seconds.
