Sif functions
WebThe specific control functions performed by an SIS are called Safety Instrumented Functions (SIF). They are implemented as part of an overall risk reduction strategy which is intended to minimize the likelihood of a previously identified accident that could range from minor equipment damage up to the uncontrolled catastrophic release of energy or … Web: The required SIF Response Time[1] (SRT). This is the interval between the SIF set-point being reached, and the hazardous event occurring. The SIF must detect and then operate its primary end elements, usually shutdown valves (SDVs) within this interval and do this quickly enough to keep the process variable below the design value.
