Efficient: Reliable and Available– Do you have existing wireless in your plant; what frequencies are being used?– Can the new system co-exist with existing plant wireless?– How close are you to potential interferences?

Assess any New System in Context of your Plant-wide Environment and Requirements

• Choose a network that supports co-existence and conserves limited spectrum.

• Partner with a professional who can assess your site and design a reliable system specific to your site– Antenna selection is important; select a radio that’s

highest allowable for your area.

Efficient: Reliable and Available

• Ensure redundant paths using self organizing mesh functionality

• Powered mesh infrastructure provides a fast mesh reformation, in seconds, with no loss of performance

Start with a Wireless Assessment for an Efficient Network Design

DCS

– Can the new system handle multiple hardware failures with no degradation in performance?– What are your uptime and availability requirements?

Reliable and Available– Secure– Scalable

12

Efficient: Secure

– Is your facility close to townships or communities?– Do you want to manage just one wireless security system or many?– Can you design and implement the security yourself?

• Consider network utilization now and in the future• Choose a network with end-to-end security that addresses

all risk scenarios.• Consider a provider that will evaluate your risks and help

design and implement a solution if desired• Choose a security paradigm that is easy to maintain

15

Efficient: Scalable

– What applications will be used now and in the future? – How many devices will you need?– Will that be enough for the lifetime of your plant?

Evaluate The Wireless Network’s Ability To Expand To Meet Your Future Goals

• Consider the plant lifetime in your design process – anticipate technology innovation enabling more devices in unexpected areas

16

Efficient: Scalable

• Research and select a system that meets your current expectations but can scale to meet unanticipated needs– Expect to double

• Avoid a rip-and-replace strategy to protect investment in training, security, and infrastructure.

Plan for Expansion Beyond What you Know Today

– What happens when you go beyond the limit of your network capacity? Can the network start small & grow?– Will more devices degrade the network performance?

Simple– Is your workforce familiar with wireless technology?– Can you afford to hire new employees to install, maintain, and expand your network?

Don’t Assume that All Wireless Solutions are Simple

• Ensure your network can integrate with your wired networks with a simple and secure structure

• Minimize software suites• Consider all plant needs to standardize • Evaluate a convenient security and authentication key

management without sacrificing security.• Choose a provider that can help train, install, support, and

maintain your solution.

• Simple Usable and Simple– Power Management



Honeywell.com

20

Simple: Power Management

– How long do you want your devices to be self powered?– Will your reporting rate needs be sustainable with self contained power, or will the device require an add-on power source?

Consider Your Reporting Rate Requirements

• Look for a system with deterministic power consumption to ensure predictable maintenance.

• Look for power management that fits both your alerting requirements and your battery replacement goals.

Honeywell.com

21

Simple: Power Management

– Will your environment support add-on power sources, i.e. solar?– What level of predictable maintenance schedule do you require?– Are you willing to accept proprietary batteries?

Simplicity Lowers Your Total Cost of Ownership

• Look for a system with deterministic power consumption to ensure predictable maintenance.

• Look for power management that fits both your alerting requirements and your battery replacement goals.

23

Universal: Application and Protocol Support

Which applications will you use over the wireless network in the future?

Your Wireless Network Should Support all Your Wireless Needs

• Keep it simple – a single network reduces risk and support costs

What communication protocols will those apps require? Will you need these protocols running simultaneously?

• Consider a system that is open, standards-based, and upgradeable to ensure future viability

Honeywell.com

24

Drive to One Network for Simplicity and Efficiency

• Research existing and pending regulations for alerting requirements– Safety shower requirements alarmed and logged

within 5-10 seconds– Sequence of events time stamping requirements

• Choose a solution provider that understands industrial requirements for integrating to control systems.

Can you afford to have your alarms and alerts transmitted back at the same rate as monitoring information?

Universal: Application and Protocol Support

Simple Usable and Simple Power Management

• Universal Application and Protocol Support– Choice


Honeywell.com

26

Universal: Choice

• Will you need one global solution?• Will you want to use multiple vendor devices on the same

wireless network?• What level of flexibility do you need?

– Will you have different applications requiring different radio requirements (bandwidth, GSM connectivity, long-haul)?

– Does your network allow choices based on 802.11 standards for cost effective solutions.

• Is it an open system that allows connection to any plant system and inherently transports existing protocols?

Evaluate How Flexible Your Wireless Network Needs To Be

27

Universal: Choice

Choose• One infrastructure that supports multiple radios

and frequencies• A solution with no barriers to future needs

These Choices Exist Now; Choose a System Upgradeable to Open Standards and New Features
