Hi,

I get the message "No license found for OPCUA IecVarAccess Provider message" in my PLC Logs when it starts up.
The product has all codesys runtime licenses intalled and runs without any problem for hours. And it says it has a support for the Codesys OPC UA server.

But the OPC UA connection drops after two hours giving a message "No license found for OPCUA IecVarAccess Provider. Demo Expired" message.

Please help how to correct this if possible.

Best Regards,

The OPC UA server is an option which the PLC vendor can add to their PLC's.
So you need to contact the PLC manufacturer to ask them to add the OPC UA license to their PLC's.
