FOUNDATION Fieldbus Safety Instrumented Functions have been successfully
beta tested and products conforming to the FF-SIF specification will be
available soon. This means big changes for the safety system market and a
change in the way end users will approach safety instrumented systems
(SISs). It is very clear that end users want this technology and are striving
to include FF-SIF systems in their project specifications. Many major end
users will probably be specifying FF-SIF systems for
their new projects starting in 2011.
