Safety instrumented systems (SIS), which are designed to take the process to a safe state in trip conditions, come in several architectures with the basic process control system (BPCS). The SIS and BPCS can be totally separate, interfaced or integrated, yet separate. While the debate on which approach is best has been going on for […]
