2 NAMUR - Info Dr. Stefan Ochs, BTS GmbH, Seite 2

3 NAMUR Recommendation NE 124 Dr. Stefan Ochs, BTS GmbH, Seite 3

4 Use of Wireless Automation in Process Industry Market Trends: Vendor s Forecast Dr. Stefan Ochs, BTS GmbH, Seite 4 Source: Advisory Group ARC

5 Use of Wireless Automation in Process Industry Market Trends: User s Expectations No Chance 3,6 % Dr. Stefan Ochs, BTS GmbH, Seite 5 Only for Specialties 28,5 % Extended Market Penetration within 5 years 57,1 % Source: Process Marktübersicht 2007

Relevant Technologies and Standards Most applications use license free ISM bands The very attractive resource license free ISM band is limited because of the great

6 Relevant Technologies and Standards Most applications use license free ISM bands The very attractive resource license free ISM band is limited because of the great number of possible applications Long term management for the coexistence of different applications must be established Dr. Stefan Ochs, BTS GmbH, Seite 6 Wireless HART

7 Motivation and Use Cases Flexibility Temporary applications Difficult access Wiring is a constraint Sensor Networks Mobile Process Operation Dr. Stefan Ochs, BTS GmbH, Seite 7 Mobility Multiple use of solutions for different applications Use of information all over the plant Substitution of cable Mobile Computing Reduced installation costs Connection of difficult topologies (e.g. flare systems, tank farm..) No abrasion (trailing cables, collector ring) by moving objects

8 NAMUR recommendation NE124 Basic Conditions addresses not only one technology (e.g. wireless sensor networks) Dr. Stefan Ochs, BTS GmbH, Seite 8 focuses on core characteristics: Reliability Availability Beneficial Use Cases

9 NAMUR recommendation NE124 General Ambitions define requirement for wireless communication in process automation define minimal requirements of technologies and devices give hints and advise for use cases Dr. Stefan Ochs, BTS GmbH, Seite 9 Major Goals prevent loss of investment drive technical developments more targeted simplify engineering and operation

10 Use classes according NE124 Dr. Stefan Ochs, BTS GmbH, Seite 10 Use Class A (Functional Safety) time critical real time applications strictly deterministic properties Use Class B (Process Control) deterministic real time applications high requirements for availability and reliability process interaction possible Use Class C (Monitoring) no time critical applications no process interaction actual available technologies meet Use Class C

11 General Requirements according NE124 Availability: radio range, etc. Reliability: bit error rate etc. Real Time Ability: latency, etc. Security: access control, encryption, etc. Interoperability: no proprietary enhancements, etc. Dr. Stefan Ochs, BTS GmbH, Seite 11 Interchangeability: keeping standards, etc. Lifecycle Management: upward and downward compatibility Energy Supply: maintenance, etc. Diagnostics: unified, significant status information

12 Engineering Engineering Tools One Tool for different Technologies (WLAN, Sensor Networks ) 3 dimensional scenarios / topologies have to be considered Dr. Stefan Ochs, BTS GmbH, Seite 12 Simulation of different scenarios (login, roaming/handover, etc.) Easy and complete documentation (transmission power, location, network addresses, needed bit rate )

13 Operation & Maintenance Easy Operation configuration by standard tools according NE 105 No loss of configuration data after energy outage Network components without process impact should be integrated transparently Dr. Stefan Ochs, BTS GmbH, Seite 13 local diagnostics according NE107 NE105: Specifications for Integrating Fieldbus Devices in Engineering Tools for Field Devices NE 107: Self-Monitoring and Diagnosis of Field Devices

14 Certification Quality Management: certification procedures assure vendor independence standard compliance efficient Life Cycle management Dr. Stefan Ochs, BTS GmbH, Seite 14

15 Open questions NE124 Requirements To establish the wide use of Wireless Automation in process industry, vendor has to provide unique, consistent and assessable KPI s and criteria for: Coexistence of Applications Dr. Stefan Ochs, BTS GmbH, Seite 15 Real Time Capability of Wireless Infrastructures Availability and Reliability of Wireless Solutions Long Term Energy Supply

16 Coexistence ISM Frequency Bands Most technologies for process automation uses the license free frequency ISM bands. But: everybody uses that and bandwidth is limited do basic technologies coexist (WLAN, bluetooth )? which limitations and interferences are known already? Dr. Stefan Ochs, BTS GmbH, Seite 16 which basic conditions are required for the application? coexistence of basic technologies do not ensure the coexistence of applications: how can vendors guarantee that? Which KPI s are used to characterize coexistence?

18 Open questions Real Time Capability Wireless Communication is non deterministic which standard guarantees real time capability? which physical restrictions are known already? Dr. Stefan Ochs, BTS GmbH, Seite 18 which basic conditions for real time capability are required and have to be provided from the user? which KPI s are used to characterize real time capability?

19 Open questions Availability and Reliability 99% availability means 4 days per year no connectivity how can vendors guarantee availability? which physical restrictions are already known? Dr. Stefan Ochs, BTS GmbH, Seite 19 which basic conditions are required for real time capability of the applications? which KPI s are used to characterize availability and reliabilty?

20 Open questions Energy Supply No maintenance effort for battery exchange how can the life time of batteries be estimated? Dr. Stefan Ochs, BTS GmbH, Seite 20 when will be reliable methods for energy harvesting be available on market? which maintenance free concepts are available for the overall life cycle energy supply? which KPI s are used to characterize the quality of energy supply?

21 Conclusions Wireless technologies in general could be an additional platform for flexible communication within or between automation systems and solutions BUT Dr. Stefan Ochs, BTS GmbH, Seite 21 there is no benefit in competition of standards (e. g. ISA SP100 und Wireless HART) NAMUR expects a common standard of best in class properties a 2nd fieldbus war is unacceptable beneficial use cases must be the center of discussions

22 Next Steps Users will prove vendors promises and capabilities of different technologies Dr. Stefan Ochs, BTS GmbH, Seite 22 NAMUR launches a Wireless Sensor Business Case and Technology Study kickoff of a WirelessHART field test at BASF SE in April 2009 to reflect NE124 requirements Emerson WirelessHART pilot Installation at Bayer and BP no proprietary technologies will be considered also ISA SP100 devices and solutions are welcome Presentation of first results at NAMUR annual meeting 2009 NAMUR will provide a NAXXX Wireless Sensor Networks in 2010

23 In this case Dr. Stefan Ochs, BTS GmbH, Seite 23 go wireless!
