Safety Instrumented Systems and ESD

In the past, Safety Instrumented Systems were strictly separate from the normal plant control systems (referred to as a BPCS (Basic Process Control System-which most people refer to as the "plant DCS"). This was done for a variety of reasons, but mainly to segregate the safety and control functions and to have higher availability and reliability. In older plants, typically the BPCS was actually a collection of pneumatic panels having pneumatic instruments and controllers. The Safety System was implemented using hardwired relays and contactors.
