    Hello,
    I have been working on configuring Rapid SCADA to send simple commands, such as starting and stopping OpenPLC, but I have not yet been able to figure out the correct approach.

    Could you kindly provide guidance or details on how to successfully send these commands from Rapid SCADA to OpenPLC?
    Thanks,
    Yousef.

    Hello,
    Does the OpenPLC use Modbus or another communication protocol?

    Yes, OpenPLC is using the Modbus protocol to communicate with Rapid SCADA.

    I recommend the video about configuring Modbus. Then ask specific questions.

    It seemed to me that the start and stop of the PLC is not related to the protocol, it is a higher level.
    But it can also be solved through protocol variables, but for this your PLC program must be written accordingly. These are fundamentally different approaches.

    In a simple version, you can control it through the start variable
    In this case, the PLC does not actually stop, it does the work of “Doing nothing”

    if (start)
    { Your program }
    else do nothing
