Please help on this regard.
connect to OPCUA server using UAExpert client. Looks like that OPCUA server is down.
How to resolve this issue
as mentioned above, use UAExpert client, connect to OPCUA server and check that server runs and nodeIDs mentioned in the logger exist. Also check message in the logger that are recorded before …
Opc UA client connected & all tags are read/write fine (in plc also all tags read/write fine).
Server is running.
Setting In below image needs to change?
can you provide printscreen from UAExpert client as evidence? Select any of nodeID mentioned in logger. Please make sure that complete path is correct.
Hello,
The reason could be that global variables are not used in the code, which means they are not created. Check this topic.
Hi all,
Thanks for your support.
The reason is variable must be used in the code to be created then issue resolved, it is not enough to enable it in the OPC UA server.
I used all unused variables in code (made it false or zero in initialization program).
