PLC Based Real Time Process Control Using SCADA and MATLAB

Abstract:

This paper presents real time control of process through Programmable Logic Controller using SCADA and MATLAB OPC Toolbox. It uses KEPServerEX.V4 from Kepware technologies as OPC DA Server that works on server client architecture. In this SCADA and MATLAB are acting as clients. The design and implementation is carried in three phases. In the first phase PLC based application has been designed, and then SCADA application were developed and integrated with process through OPC server. Finally, MATLAB SIMULINK model is designed for accessing real time process data. The realization of the test system has been validated using Mitsubishi FX2N 32MR PLC, CitectSCADAv2 and MATLAB. The control of process and results of test system show efficient and reliable exchange of real time data between PLC, MATLAB and SCADA.
