    Hi i am using the unified Automation UaExpert for connecting to the raspberry. However when i connect the client to the server using the opc.tcp://<network address="">:4840 i am able to connect but i cant see any variables which i have declered in the symbol configurator to be both writable and readable
    Any one that have been exepericing the same problem or someone that know what i have missed or what i have done wrong?</network>

    Hi,

    yes this is an accident in 3.5SP8 (which will be solved with 3.5SP8Patch1)
    The Workaround would be:
    To have GVL which does publish some variables (additional beside this OPC variables in PLC_PRG from the example)

    this workaround does not seem to work for me (using codesys V3.5 SP8+)...
    My OPC-UA client is an android app from Prosys (https://www.prosysopc.com/products/opc- ... r-android/)
    I get the same result as above: i can browse up to the application level, but i can't see my variables. I have 1 extra global var defined just like in the example.

    restarting everything solved the problem...
