hi all,
in almost all books it is given as the PLC is better for discrete (ON/OFF) control, and interlocking operation. Although PID loops can also be implemented. similarly it is said that DCS is better for PID control.
my question is why there are restrictions on PLC and DCS to the tasks of each other? example if one PID loop can implement on PLC, why cant multiple? and why DCS is not good for discrete operations?
thanks
