2008 – The Year of Industrial Wireless?

• Maybe …– Standards emerging:

– Wireless HART, spec approval by 2007 year end

– ISA100, spec approval during 2008

– Mesh networking reliability challenge resolved:– Dust SmartMesh >99.9% data throughput

– Early adopter products enjoying commercial success:– Emerson 1420, etc.

• Maybe not …– Security– Interoperability and compliance– Integration with existing business processes

Whatever the Year – Most Want Wireless for Monitoring and Alerting

Typical Wireless Deployment – ALL NEW!

• New wireless transmitters:– Expensive

– How do I provision these?

• New network:– Where do I put these repeaters?

– How do I know the signal is actually getting through?

– Can I trust the data on the other end?

– What if my control process gets all messed up?

• New software:– How do I integrate this stuff with

my existing systems?

– Is this really going to work with my DCS?

An Alternative – Retrofit Your Wired Instrumentation

• Add wireless adapters to existing 4-20mA-only smart devices (e.g. HART)

• Continuously access smart device info– Device status

– Diagnostics

– Configuration

• Use standards (e.g. OPC) to connect data to enterprise systems … PAM, CBM, etc.

• Bypass the DCS

PAM Manages Performance, Availability, and Reliability of Plant Assets


PAM

PAM Use Cases – Smart Valves

• Abnormal position vs. valve demand

• Automated detection of valve or positioner malfunctions

• Faster and control-room based troubleshooting and routine testing

• More accurate problem diagnosis– Fewer false positives and

needless valve teardowns– Fewer unnecessary

replacement parts• Valves operate closer to

rated performance– Possible results: Increased

plant capacity, higher yields, greater process efficiency

What’s Driving PAM?

More and more plant assets

Smaller size of field staff

Aging boomer workforce retiring

More loops per technician (500 to 2000)

Less expertiseper technician

Managing plant assets now takes more than just the workforce

PAM Use Case – Measurement Instruments

• Detect and resolve problems more quickly and efficiently– Alert operators and

maintenance before process degrades

– More efficiently schedule repairs

• Save labor on routine calibrations– Don’t need to be located– No handwritten reports– Results are digitized and

available as documents

PAM Enables Predictive Monitoring & Maintenance

• “Industry reports estimate that by changing 25% of all preventive maintenance to predictive maintenance, which is five times less costly than preventive maintenance, an organization could potentially realize an up to 60% reduction in maintenance expenses alone.”

• $50,000,000 /year in maintaining 40,000 points =$1,250 per point/per year

Predictive monitoring & maintenance require field data that is often unavailable other than via manual surveys, if at all.

– Provide backup primary variable signals for operators

PAM Wireless

• Add measurement points via adapters to:– Better manage machinery and production

assets

Reaping the Benefits of Standards-Based Wireless and PAM

Problem Solution

Valuable information locked in smart field instruments.

Wirelessly access locked data via WirelessHART adapters for improved monitoring and PAM of automation assets.

Waiting for manual surveys to identify equipment problems is often too long.

WirelessHART adapters and new wireless measurement points enable continuous, predictive monitoring of assets.

Detecting and troubleshooting instrument problems is time consuming.

WirelessHART adapters cuts time-to-resolution by continuously enabling remote diagnostics and problem solving.

Manpower reductions, aging workforce.

Automate collection of field data to let staff focus on highest value activities.

Reaping the Benefits of Standards-Based Wireless and PAM

Problem Solution

New monitoring points for equipment assets involves costly runs of wire between DCS and field.

Field-powered wireless adapters add new PAM (or process) measurement points without long wire runs and use existing 4-20 mA instruments.

Incomplete field-data picture complicates time-sensitive decisions.

Broaden access to real-time data via retrofits of existing devices and addition of new points to improve decision making.

Extra costs of under (or over) maintaining assets.

Comprehensive picture of plant health cuts operating costs and improves plant productivity.

Getting data needed for PAM from plant through DCS is difficult.

Wireless networks bypass legacy DCS and integrate real-time monitoring data with plant management and enterprise systems.

Agenda

• 2008 – The Year of Industrial Wireless?• Plant Asset Management Baseline• Turbocharging PAM with Wireless• Suggested Best Practices• Conclusions and Q&A

Accelerate Learning Curve by Piloting

• Start piloting now!– Certified standard-based products not available for at least a year – Learn how reliable and easy-to-use (or not) today's technology is– Learn about the RF nuances of your environment

• Stand-alone pilot– Do not integrate pilot with existing processes– Set up test processes for the stand-alone system

• Retrofit– Low-cost, low-risk piloting– No need to install new devices

Deployments in ’08 and Beyond

• Use standard-based products – Wait for availability– Extract upgrade commitment from vendor

• Understand use of data – Who are the human users of the information generated? – What systems do they rely on?

– DCS? – Historian? – PAM?

• Understand integration issues with existing processes – Single HMI or NOT? – Process modifications or NOT?

• View wireless’s ability to bypass the DCS as strategic for plant management and enterprise applications
