WinCC® application via OPC communication to MatLab® for integrated systems

This paper focuses on implementing an application for the integration of systems. The possibilities of the OPC communication regarding applications in control, identification and failure detection are shown. Two processes are discussed: a DC motor and a fed-batch reactor. An application with the SCADA WinCC reg system, which communicates with applications in MatLab reg/Simulink, allows the identification of a DC motor, which is identified in MatLab reg for failure detection; and sensitivity to initial conditions is analysed in a nonlinear fed-batch reactor, which is simulated in MatLab reg to know future operation
