Answer Posted / aj
1. PLC is uni-tasking while DCS is used for multitasking.
2. DCS is dealing with very large no. of I/O while PLC has less no of I/O.
3. Normally DCS always comes with SCADA while in PLC its optional.
4. If DCS is stopped, all system is stopped respectively while in cascade PLC , if one stop working other will continue to work.
