What is difference between PLC, DCS and SCADA
Currently there are two main stream types of control systems - PLC-SCADA and Distributed Control Systems (DCS).
DCSs were traditionally used to control large processes, while PLC systems were used to control machines. Since the introduction of PC Windows-based SCADA systems and Ethernet networks, the dividing lines between DCS and PLC-SCADA systems have become blurred.
PLC-SCADA solutions cater to meet specific client needs but require extensive work to manage the associated complexity of the PLC and SCADA software. A PLC-SCADA solution is characterised by its open nature, flexibility, complexity and can be considered to be a blank canvas.
