Fieldbus Foundation Launches End User Demonstration Project For Safety Instrumented Systems

Automation industry leaders gather in Amsterdam for kick-off meeting

HANNOVER, Germany, April 24, 2006 — The Fieldbus Foundation, conducting a press briefing at the INTERKAMA Trade Fair in Hannover, Germany, today announced the launch of a major demonstration project supporting implementation of Foundation fieldbus Safety Instrumented Systems (SIS) technology.  Leading process instrumentation end users and suppliers attended a kick-off meeting on April 5-7 at Shell Global Solutions in Amsterdam, The Netherlands.

Foundation fieldbus, with its industry-proven distributed function blocks and open communications protocol, is an ideal platform for advancing standards-based Safety Instrumented Systems.  The Fieldbus Foundation developed SIS specifications and guidelines in cooperation with the world's leading end users, controls manufacturers and safety experts.

The end user demonstration, to be conducted at the Shell Global Solutions facility in Amsterdam, will promote adoption of the foundation's SIS technology in the process industries.  The project will include development of SIS best practices and guidelines, training, test tools, and a field demonstration of compliant safety instruments, logic solvers, and other related equipment.

Companies participating in the demonstration working group include: ABB, BIFFI, BP, Chevron, Cooper Crouse-Hinds, DuPont, Emerson Process Management, Endress+Hauser, ExxonMobil, Fieldbus Diagnostics, HIMA, Hirshmann, Honeywell, Invensys, Magnetrol, Metso Automation, Moore Industries, MTL, Pepperl+Fuchs, Saudi Aramco, Shell Global Solutions, Smar, Softing, TopWorx, TÜV Rheinland, Westlock Controls/Tyco and Yokogawa.

The Fieldbus Foundation's director of technology development, David A. Glanzer, said, "The foundation's SIS technology will enable end users to realize significant reductions in their total cost of ownership by extending Foundation fieldbus benefits into plant safety systems.  The major automation suppliers support SIS technology because they can market open, interoperable fieldbus devices instead of being limited to proprietary system platforms.  End users support SIS because they can now choose ‘best-in-class' SIS devices from the suppliers of their choice, just like they enjoy today for non-SIS devices."

Glanzer continued, "In addition, controls manufacturers implementing SIS can comply with recognized international standards.  The foundation's SIS protocol meets the rigorous requirements of the IEC 61508 standard for functional safety of electrical, electronic and programmable electronic safety-related systems, up to, and including, Safety Integrity Level 3.  TÜV Rheinland Industrie Service GmbH, a global, independent and accredited testing agency, granted the Protocol Type Approval last year."

With SIS products, end users can build systems per the IEC 61511 standard covering SIS functional safety in the process industries.  IEC 61511 is also available as the ANSI/ISA-84.00.01-2004 standard.  End users can benefit from the powerful diagnostics available with Foundation fieldbus, and at the same time, maintain the protection of a SIL3 environment.  No changes were required to the existing Foundation fieldbus H1 protocol to add the safety instrumented systems protocol extensions.

The Fieldbus Foundation's board of directors approved the SIS specification development project in October 2002.  The project development team achieved its first major milestone at the end of 2003 with TÜV approval of the overall system concept.  In October 2004, the Fieldbus Foundation announced completion of Draft Preliminary Specifications for the SIS development.  During 2005, laboratory tests validating the specifications were successfully completed at R&M Industrieservice, an independent consultancy based in Frankfurt.  Final Protocol Type Approval for SIS was granted by TÜV at the end of 2005.
