  • Date To 5th February 2021
  • Price Free of charge, open to all.
  • Location Online: 09:00 GMT. Duration: 1 hour.


A Safety Instrumented Function, or SIF, is one or more components in a protection layer designed to execute a specific safety-related task to achieve or maintain a safe state for the process in the event of a specific dangerous condition or hazardous event. We will look at the design of such SIFs, including:

  • main concepts and definitions
  • random hardware failures
  • hardware fault tolerance
  • systematic capability for the target SIL level
  • key parameters
  • common pitfalls.
