DCS System consists minimum of the following components.
1. Field Control station (FCS): It consists of input/output
modules, CPU and communication bus.
2. Operator station: It is basically human interface
machine with monitor, the operator man can view the process
in the plant and check if any alarm is presents and he can
change any setting, print reports..etc.
3. Engineering station: It is used to configure all input &
