Answer Posted / bhaveshsavaliya

As we define PLC as programmable logic control,it has some
limitation related to its features like limitation of its
input/outputs,No.of Analog/digital interface and many other
which are applicable for only one particular application.

While DCS is also a control used for same application as
PLC,but when it Comes to your applications,you must know
difference between this ,For Example Like mega Power plant
or big capacity Refinery,where multiple task where
controlling at same time, which could not possible via
PLC,but we have to make mass communication between such PLC
modules which controlling such different task and give
feedback to masters,this will then define as Distributed
control system and make a huge task possible without any
Complication,consumption and failure.
