The Fieldbus Foundation ( published a white paper on FOUNDATION(tm) Safety Instrumented Functions (SIF) on its Web site. The paper, authored by the research firm ARC Advisory Group (, describes the implications of FOUNDATION SIF (FF-SIF) technology for the global plant safety system market and end-users.

According to the ARC document, entitled FOUNDATION Fieldbus Safety Instrumented Functions Forge the Future of Process Safety, successful beta testing of FOUNDATION SIF means big changes in the way automation end-users will approach Safety Instrumented System (SIS) implementations in process industry plants. In the paper, Larry O”Brien, ARC Advisory Group”s research director for Process Automation, describes how FOUNDATION SIF is a critical part of the FOUNDATION fieldbus automation infrastructure.

The white paper reviews the history and development path of FOUNDATION SIF technology, and provides insights into topics such as: SIF product registration, conformance to international standards, diagnostics functions and benefits and future challenges. It also outlines key advantages of FOUNDATION SIF at the safety system layer.
