Dear All,

Mapp view pages are developed and running in @ PPC2100, Operating System: Linux, (Hypervisor installed) from last one month.

but some time server connection error came in PPC display & kicked out.

Log error finds below

even removed all error but still server connection error is coming.

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.
