Design, operation and maintenance of Safety Instrumented Systems (SIS) just got easier

exSILentia Version 3 adds capabilities that will help users achieve a new level of consistency and productivity in the design of their Safety Instrumented Systems (SIS). This release enhances the existing suite of tools, including the industry leading tool for Safety Integrity Level (SIL) verification (SILver®). All-new functionality allows users to follow the entire IEC 61511 / ISA 84 functional safety lifecycle for the first time using a single tool. It also supports compliance with regulations such as OSHA PSM 1919.119 (USA) and Seveso II (Europe).
