In January 2006, the Fieldbus Foundation announced that TÜV Rheinland Industrie Service GmbH, Automation, Software and Information Technology, a global, independent and accredited testing agency, had granted Protocol Type Approval for its Safety Specifications.
The Foundation Technical Specifications - Safety Instrumented Functions are in compliance with International Electrotechnical Commission (IEC) 61508 standard (functional safety of electrical/electronic/programmable electronic safety-related systems) requirements up to, and including, Safety Integrity Level 3 (SIL 3).
Approval clears way for standards-based devices
With the TÜV Protocol Type Approval, Foundation technology has been extended to provide a comprehensive solution for safety-instrumented functions in a wide range of industrial plant applications. The specifications enable manufacturers to build Foundation registered devices in compliance with IEC 61508. Third-party test agencies such as TÜV will certify that these devices are suitable for use in safety-instrumented functions. End-users will be able to choose devices meeting the requirements of IEC 61511 (functional safety: safety instrumented functions for the process industry sector) from multiple suppliers, instead of being restricted to devices designed specifically for a proprietary safety system platform. IEC 61511 is also available as an ANSI/ISA Standard: ANSI/ISA-84.00.01-2004.
Cooperative effort achieves major milestones
The SIF project was initiated by end users and approved by the Fieldbus Foundation's board of directors in October 2002. Companies participating in the project included: ABB, BIFFI, BP, Chevron, Dresser-Masoneilan, Emerson Process Management, Endress+Hauser, Fieldbus Diagnostics, HIMA, Honeywell, Invensys, Magnetrol International, Metso Automation, Moore Industries, MTL, Pepperl+Fuchs, Risknowlogy B.V., Saudi Aramco, Shell Global Solutions, Siemens, Smar, Softing, TopWorx, TÜV Rheinland, TUV SUD, Westlock Controls/Tyco and Yokogawa.
The development team achieved its first major milestone at the end of 2003 with TÜV approval of the overall system concept. The development team met with external experts at a meeting hosted by Shell Global Solutions in Amsterdam, The Netherlands, in March 2004 to review the initial specifications. Comments from this review were resolved and the management team developed the top-level project plan for laboratory validation testing.
During the lab test phase, conducted at the BIS Prozesstechnik GmbH facility in Frankfurt, Germany, each prototype supplier independently implemented the foundation’s safety instrumented systems specifications. In parallel, the test team separately developed test cases and prepared expected test results.
Specifications meet the demands of plant safety
Extensive laboratory testing and application analysis has verified that the foundation’s safety instrumented systems technology meets the needs of industrial end-users, who regard these systems as critical to their overall plant operating strategy.
TÜV Type Approval will help meet the growing worldwide demand for commercial, standards-based, safety instrumented system products incorporating Foundation technology. End-users can now adopt the powerful Foundation diagnostics, and at the same time, maintain the protection in up to a SIL3 environment. No changes were required to the existing H1 protocol to add the safety instrumented systems protocol extensions, clearly indicating the value of the comprehensive, forward-thinking design of Foundation technology.
Foundation launches field demonstration project
The Fieldbus Foundation has launched a major demonstration project supporting implementation of the Foundation SIF implementation. End user demonstrations were conducted by Shell Global Solutions in The Netherlands, Saudi Aramco in Saudi Arabia, BP in Germany and Chevron in the United States, to promote adoption of the technology in the process industries. The project will include developments of SIS best practices and guidelines, training, test tools, and field demonstrations of compliant safety instruments, logic solvers, and other related equipment.
Companies participating in the demonstration working group include: ABB, BIFFI, BP, Chevron, Dresser-Masoneilan, Emerson Process Management, Endress+Hauser, Fieldbus Diagnostics, HIMA, Honeywell, Invensys, Magnetrol International, Metso Automation, Moore Industries, MTL, Pepperl+Fuchs, Risknowlogy B.V., Saudi Aramco, Shell Global Solutions, Siemens, Smar, Softing, TopWorx, TÜV Rheinland, TUV SUD, Westlock Controls/Tyco and Yokogawa.
