Issue with connection with KepserverEx

Alchen — Thu, 08 Jan 2026 02:36:57 GMT

Hello everyone.

We use KepserverEx as OPC UA server and MCE get tags from KerserverEx. Looks like there are some limitation in Kepserver side, MCE can't get more than 1K tags at the same time, if exceed the limitation, the tags will be null.

We tried to separate tags into several devices in Kepserver but didn't works.

Greetings,

We have reviewed the Kepware OPC UA documentation and did not find any limitations related to the issue you are encountering. To help us isolate the cause, could you please verify whether you are able to retrieve the tags using the OPC UA Expert tool?

Kindly check and confirm if the same issue occurs in the OPC UA Expert environment as well. Your feedback will help us proceed with further troubleshooting.

Regards,
Mohit

Thanks, we try to separate into several connections, but the issue still happen, that means it's not this kind of issue.
