Difference between PLC and DCS
==========================

PLC for Discrete control like automobile industry....DCS for analog control like oil and gas
PLC centralized DCS distributed control System
High Response time DCS,
Monitoring OF DCS, PLC Need HMI
DCS predefined function
Response time of PLC is high
DCS takes much longer to process data, so it’s not the right solution when response times are critical safety systems require a separate controller.
A PLC can only handle a few thousand I/O points or less
DCS, which can handle many thousands of I/O points and more easily accommodate new equipment
Redundancy in DCS
Frequent process changes
PLCs are best applied to a dedicated process that doesn’t change often.
Logic development
PLC can programmed be programmed based on our application.
DCS comes with built-in control functions
Cost of DCS is high
