Unable to read OPC UA variables from server


I am able to detect the variable under Node ID and I tried to use the code below to read the variable value but unable to do so. In another OPC UA client that I tested, it is able to read the value just fine. The server is a python script running locally attached below. Would appreciate the help.

New Python File.py

double value = Emulation.Variable("myvar").value;
return value;

It works for me on a local host :

Can you try that? If that works I wonder if it could be a security issue.

Ok the issue is resolved. I think I did not reset and run my model, that could be the reason why the variable value did not update. Thanks for your time!
