  1. Fieldbus Foundation • Safety Instrumented Systems • (FF-SIS) • ____________________ • Dave Glanzer • Fieldbus Foundation • Director of Technology Development

  2. FF-SIS Scope • Extends FF Technology to Safety Instrumented Systems • Based on the IEC 61508 International Standard. • Example Application Areas: • Burner Management Systems • Fire & Gas • Fuel Engineering

  3. International Development Team ABB AS Norway ABB Instrumentation Italy BIFFI Italy E.I. DuPont de Nemours, Inc. USA ExxonMobil Research & Engineering USE Emerson Process Management USA Flowserve USA HIMA Germany Honeywell SMS The Netherlands ice-PROS Canada Infraserv Höchst Technik GmbH & Co.

  4. FF-SIS End User Requirements • Reduced Total Cost of Ownership for FF-SIS applications. • CAPEX • Hardware, Footprint, Commissioning, Power Consumption • OPEX • Advanced diagnostics, Reduced test interval via increased DCF. • SIL 2 and 3 applications • Password protected access to FF-SIS field devices • Additional Function Blocks (e.g. logic, 2 out of 3 voting) • Definable actions on diagnosed failures – trip, message • Handle discrete signals (e.g. switches, motor trips, lights, push buttons, etc.) where H1 dynamic performance is acceptable

  5. FF-SIS End User Requirements • Total system approach • Total Asset Management – FF-SIS and Non-SIS • Modular Logic Solver –centralized and distributed option • Diagnostics • Hybrid system architecture – FF-SIS & traditional hardware • Guidance to manual proof test • Signalling/procedures for auto proof test • Awareness of opportunity-based proof test • Logging/documentation of results • Failure rate updates

  6. FF-SIS Extension Areas • Communication • Meet IEC 61508 part 2 clause 7.4.8 Communication Diagnostics • User Application • Meet IEC 61508 part 3 clause 7.4.4 Function Block Diagnostics CRC on Device Description Files

  7. FF-SIS Communication Extensions • Black Channel Approach • H1 Communication System (Black Channel) is unchanged. • A new FF-SIS protocol above the Black Channel detects network faults and appropriate action is taken without human intervention. New FF-SIS Communication Diagnostics IEC 61508 Black Channel IEC 61508

  8. FF-SIS User Application Extensions • User Application • New Function Blocks for FF-SIS Applications – FBAP Part 6 • New FBAP diagnostics detect application faults and appropriate action is taken without human intervention. New FF-SIS Function Blocks & Function Block Diagnostics IEC 61508 Black Channel IEC 61508

  9. FF-SIS User Application Extensions • Function Block Application Process – Part 6 • SIS Write Lock • SIS Discrete Input • SIS Analog Input • SIS Discrete Output • SIS Analog Voter • SIS Discrete Voter • SIS AND/OR/XOR FF-SIS Diagnostics and Statistics added to device Resource Block
