SIF Definitions during the SIS Lifecycle
Defining safety instrumented functions is a critical task that happens very early in the SIS safety lifecycle. Mistakes during this phase can cascade into errors persisting throughout the entire SIS safety lifecycle. Some common errors include associating every action for a sensor in a cause-and-effect diagram, ignoring multiple sensors that can detect a hazardous condition, and improperly voting a large number of sensors – many of which cannot detect a hazard simultaneously.
This webinar presents a series of rules that will allow SIS designers to properly define safety functions prior to SIL selection and SIL verification steps.
