Laboratory testing will validate fieldbus safety instrumented system specificationsHOUSTON, Texas, Oct. 5, 2004 — The Fieldbus Foundation, conducting a press briefing at the ISA EXPO 2004 Exhibition & Conference in Houston, Texas, today announced the completion of Draft Preliminary Specifications (DPS) for its Fieldbus Foundation-Safety Instrumented Systems (FF-SIS) development. Laboratory tests of the DPS will be conducted at Infraserv Höchst Technik GmbH & Co. KG, an independent consultancy located in Frankfurt, Germany, that will validate the FF-SIS specifications.The FF-SIS project provides an open solution by developing technical specifications and guidelines that enable manufacturers to build Foundation fieldbus devices in compliance with international standards. Third-party agencies will certify that these devices are suitable for use in safety instrumented systems. The FF-SIS project will allow end users to choose certified instruments from multiple suppliers, instead of being restricted to devices designed specifically for a proprietary safety system platform.TÜV Anlagentechnik GmbH, Automation, Software and Information Technology, a global, independent and accredited testing agency, approved the FF-SIS system concept at the end of 2003, clearing the way for validation testing. A multi-vendor development team and external experts at a meeting hosted by Shell Global Solutions in Amsterdam, The Netherlands, in March 2004, subsequently reviewed the FF-SIS specifications. Comments from this review were resolved and the FF-SIS management team evaluated the top level project plan for laboratory validation testing at a meeting hosted by ABB in Oslo, Norway, in August. ABB is leading the laboratory test program.Infraserv Höchst Technik will host an upcoming meeting of the FF-SIS development team, test team and laboratory prototype suppliers to develop a detailed schedule for the validation testing. During the test phase, which will be conducted at Infraserv’s facility in Frankfurt, each prototype supplier will independently implement the FF-SIS specifications. In parallel, the test team will separately develop test cases and prepare expected test results.According to ABB Corporate Research’s Trygve Harvei, FF-SIS lab test manager, close cooperation by all participants has helped the FF-SIS project to meet its key milestones. “The FF-SIS development is on track to reach full specification status, and this progress is due to the dedicated efforts of all the participating companies,” said Mr. Harvei. “Our project for employing fieldbus technology in the safety systems arena is of utmost importance to the process automation industry. There is a growing worldwide demand for commercial, standards-based, safety instrumented system products incorporating the FOUNDATION fieldbus protocol.”Fieldbus Foundation Director of Technology Development David A. Glanzer anticipates successful validation testing of FF-SIS. “Rigorous laboratory testing will verify that the FF-SIS concept meets the needs of industrial end users, who regard safety instrumented systems as critical to their overall plant operating strategy,” he said. “This program has significant implications for the broader implementation of fieldbus.”Glanzer indicated that any deviation between actual and expected test results during the laboratory validation phase would be analyzed and resolved by the FF-SIS test team. At the end of the testing, the FF-SIS team will update the DPS to a Preliminary Specification (PS) for review by the entire Fieldbus Foundation membership.The FF-SIS project was initiated by end users and approved by the Fieldbus Foundation's board of directors. The resulting specifications and guidelines are in compliance with the International Electrotechnical Commission (IEC) 61508 standard (functional safety of electrical/electronic/programmable electronic safety-related systems), and IEC 61511 (functional safety: safety instrumented systems for the process industry sector).Companies participating in FF-SIS development and test include: ABB, DuPont, Emerson Process Management, ExxonMobil, Fieldbus Diagnostics, Flowserve, HIMA, Honeywell, ICE-Pros Inc., Invensys/Triconex, Metso Automation, Rockwell Automation, Rotork Control Systems, Saudi Aramco, Shell Global Solutions, Smar, Softing, TÜV, Tyco/Westlock and Yokogawa.About the Fieldbus Foundation™The Fieldbus Foundation is a not-for-profit corporation consisting of nearly 350 leading process and manufacturing automation companies worldwide whose major purpose is to provide an open and neutral environment for the development of an international, interoperable fieldbus. In this environment, end users, manufacturers, universities and research organizations are working together to develop the technology, provide development tools, support and training, coordinate field trials and demonstrations, and enable product interoperability.
