SCADA abbreviated as Supervisory Control and Data Aquision. Simply it will collect the date from the hardware controller (DCS, PLC) and shows the process variables like Pressure, Temperature, Flow, Level etc.This software product used to monitor, control(by using back end Hardware controller like DCS, PLC etc) your process data
Whereas DCS abbreviated as Distributed Control System. DCS having it's own network, Hardware controller and Software Package. The system having different Hardware controller connected in the network (own by individual vendor like Honeywell, Yokogawa, Foxboro, ABB, Emerson etc) and shows the process variable through SCADA S/W. It's integration of Hardware (different types) and Software using the common network.
