A Review
Distributed control system (DCS)—a computer-based system that
controls and monitors process variables. The main role of the DCS
is to handle BPCS (basic process control system) actions, to
“adjust” the process to make it run smoothly. However, the action
of the BPCS is not only regulating or throttling a valve (control
valve); it could also be opening or closing a valve!
Programmable logic controller (PLC)—a simple, stand-alone,
programmable computer. The role of the PLC is to handle
SIS (Safety Instrumented System) actions. The SIS is
not an adjusting, regulatory action like BPCS but rather
a direct action, which may involve opening a valve, shutting down,
or starting up a pump. It is a drastic action,
intended to protect equipment from damage and to keep
operators safe. These may be called “safety
interlocks.”
