WebAbout Integration Between SIS Management and LOPA. Integration between SIS Management and LOPA helps in assessing the SIL level for Instrumented Functions. To assess the SIL level for an Instrumented Function using LOPA: Perform a LOPA for the risk that the instrumented function is designed to mitigate. A LOPA record will be created. WebLOPA can be used to make decisions regarding risk in a hazardous scenario. A scenario is an unplanned event that results in an undesirable consequence. LOPA is usually applied …
