Hi

I have been setting up an OPC UA Client interface in a V16 project to browse the tags on an S7-1516F OPC UA server and it works fine, I am able to connect to the server through the Online Access of the client interface setup.

However I want to try the OPC_UA_ReadList_C function so have opened exactly the same project up in TIA V17 and now when I try to browse the OPC UA server in the client interface it says it can't find any servers. If I recreate the project from scratch in V17, still nothing.

Is there something else I need to configure in V17 to allow this?

Thanks

Hello TheStirrup
