    Hello everyone,

    i am trying to set up a DA to UA Gateway.

    However i do have problems receiving values from my DA Server.
    I am able to browse the server variables, can add variables to a channel,
    but i dont get any values displayed.

    Rapidscada and the OPC DA Server are running on the same machine.

    In the Line log it says, that the value to be received is “(unspecified)”

    Can you compare the received data (unspecified) with data collected by any other OPC client? For example, Prosys OPC UA Browser.

    Communicator works as a service with the system account, while most of OPC clients work as an application.
    Try the following:
    1. Stop the ScadaComm6 service.
    2. Open command line and execute ScadaCommWkr.exe
    What will you get in ScadaComm.log and communication line log?

    Hi Mikhail,

    stopping the service and starting the worker did the trick
    and i do receive values now.

    This seems to be working.

    The OPC UA server is having troubles though. As you can see there are some problems regarding opening listener sockets.
    I am able to connect to to UA Server with UA Expert but i dont have access to
    the variables. I can browse the tree up to the device folder but thats it.

    Thank you very much for your help so far.
    Greetings.

    Looks like the ScadaComm6 service is not stopped. Users OPC-WINCC$ and OPCSrv are mixed in the log file.

    That was the problem, indeed. Its working now, thanks a million times.

    Is there a way to restart the OPC UA server after adding new variables
    to the subscription group? I always have to reboot the entire pc
    to make it work.

    You should try the setup the ScadaComm6 service to work as the OPCSrv user. See this.
    It’s enough to restart Communicator that works as a service or application.
