#KepserverEx#How KepserverEx tag as null or extremely big/small value

[Alchen]

Hey guys.

Currently we use KepserverEx ( Version: v6.10.659.0)  as OPC UA client, collect data from a pair of GE iFIX Servers, meanwhile KepserverEx also as UA server to provide data to cloud.

We check from cloud and find out some tags will be interrupted for minutes, also some are unreasonable value(extremely big/small) occasionally.

I wonder to know in what case, Kepserver will tag the variable as null or extremely big/small.

Attached is event log from KepserverEx.

Greetings,
 

Upon reviewing the shared logs, we identified the following error:
"The node ID refers to a node that does not exist in the server address space" (Status Code: 0x80340000).

We have a reference article that addresses this specific behavior. Please review the documentation and apply the recommended changes:

Please keep us updated on your progress, and let us know if the issue persists after these adjustments.

Thanks, could you tell me if Kepserver marked it as bad quality, meanwhile, UA client will get null in this tag from Kepserver ?
