Codesys OPC UA not working?

    I'm currently using Codesys 3.5 SP 18 on an Wago PFC200 (750-8212). In the WBM I turned the Wago OPC UA server off. I make a GVL and Symbol Configuration and exported the GVL.

    When using Prosys OPC UA Client to check for the variables I only see DeviceSet -> CODESYS Control for PFC200 SL -> Resources but no underlaying GVL or variables.

    What goes wrong?

    You say that you turned the OPC/UA server off. I would think that you have to have the OPC/UA server on to be able to reach it from the client....

    no there is an OPC UA server embedded in the CODESYS Runtime, therefore it must be turned off.

    The internal one on the Wago page is not the Codesys OPC UA server right?

    How is it possible I don't see any Symbols?

    I have deleted the Symbol Manager and added a new one and now it works.
