Answer Posted / palak majmudar
1) PLC can not handle complicated loops and can not give
accurate result of close loops, it is only useful for very
simple application loops; while DCS can handle very complex
cascade loops and give very accurate controls to process
equipment using some inbuilt or predefined algorithms in
programming.
2) PLC has limitation in expansion of closed loops; While
DCS can handle no. of closed loops without any interruption.
3) PLC is useful for very small plant application; while
DCS is useful for integration of small-small plant and to
bring those all on a single platform.
