    I have been trying to do CODESYS data encyrption through OPC UA. Regarding that I can connect my Ua Expert or OPC Expert with my CODESYS program through OPC UA server. But the issue I got that OPC server can't browse my CODESYS program application. Did I miss anything? I have tried in so many ways but nothing worked out so far. Attached Ua Expert browsing failure image

    Could you show your "Symbol configuration" in Codesys? Did you enable the OPC-UA features and also selected the variables with correct permissions?

      Yeah I enabled OPC-UA feature there. I followed the following link:https://help.codesys.com/webapp/_cds_runtime_opc_ua_server;product=codesys;version=

      I tried in many ways but it didn't work. Atatched my program Symbol Configuration image

    Solved the issue. To fix this issue following steps should be taken:

    UAExpert: add the PLC name to hosts file. connect to PLC hostname rather than local Control Win.

    OPCExpert: add the PLC name to hosts file. Add the PLC to the "Network", rather than adding it to "This PC"
