Adhering to International Safety Standards with DeltaV SIS and the SZ Controller

  The DeltaV SIS with Electronic Marshalling architecture provides many benefits whether deploying an integrated control and safety system (ICSS) or a separate, stand-alone SIS. The international standards for functional safety in the process industry, IEC61511 (or ANSI/ISA 84) require that the safety system be independent of the distributed control system (DCS), with separate power supplies, communication channels and control execution. When designing your safety instrumented system (SIS), it’s important to understand the purpose of each hardware component to ensure your system adheres to these standards. One of the more common questions we hear from users considering DeltaV SIS is: .
