I have troubles getting connection to XSOFT Codesys OPC UA server via UaExpert software.
I'm trying to connect Eaton PLC XC303 with modules 16DIOPD05 and 4DORNO to OPC UA server. I did the symbol configuration and enabled the build the PLC symbols to the UA server. From the device log directory I found the correct IP address that I passed to the new server in the UaExpert. Now it gives me error:
"The server returned no certificate all certificate checks will be skipped."
Any idea how to configure this certificate working? There is attachment showing the error in UaExpert.
The help has all the steps.
Make sure you download the Security agent from store.codesys.com
It is possible you won't be able to create or use a certificate, if you have an (older?) version of the runtime which doesn't have the security feature included. In which case, it is checking with Eaton what to do.
Alternatively, don't use encryption with OPC UA expert
I fixed the problem by deleting the administrator rights (tricky to do) and now I didn't need to do any additional "trusted" certificates.
