What is Future Trends in Safety Instrumented Systems about?

This document discusses future trends in Safety Instrumented Systems (SIS) and the requirements for safety programmable logic controllers (PLCs). It notes that about 18% of Safety Instrumented Functions (SIFs) require SIL 3 or higher integrity levels. As safety PLCs often control multiple SIFs, including some at SIL 3, they are generally specified as SIL 3 devices. The document also discusses how accumulated risks across multiple SIFs and the potential for shared spurious trips can drive requirements for SI
