Hi!
I have a user interface programmed in WinCC and a PLC-program that is run in S7-PLCSIM. I want to make a simulator in MATLAB Simulink and therefore I have used MATLAB OPC Toolbox to connect to the OPC Server in WinCC. I can read the values, but i can not write. Every time I try to write, my values are overwritten..

Does anyone know this happens? And does anyone know if there is something I can do to write values from MATLAB Simulink to the S7-PLCSIM (via OPC Server in WinCC).

Regards,
sivkat
