Chementator: Foundation for SIF Demonstrations    

By Gerald Ondrey |

This month, the newly released Foundation for Safety Instrumented Functions (SIF) was demonstrated at Shell Global Solutions (Amsterdam, Netherlands) — one of several demonstrations planned by the Fieldbus Foundation (FF; Austin, Tex.; edlinks.chemengonline.com/7372-545). In Amsterdam, engineers constructed a DCS-controlled demo rig with graphic panels showing safety devices and SIF functions, including an operator interface for partial stroke testing and asset management diagnostic information. The Foundation SIF installation includes three fieldbus segments with hardware from three different suppliers. Engineers will evaluate system integration capabilities with asset management and Basic Process Control System platforms. The FF’s SIF protocol meets the requirements of the IEC 61508 standard ( CE, May 2005, pp. 25 – 28) up to, and including safety integrity level (SIL) 3.   Click here for a full pdf version of the Chementator Section
