Yes. Make some more tag groups and spread the tags among them. That is usually sufficient in such cases.

Unless you are hitting the total limit in some servers, like PLC built-in OPC.

I'm going to type "Bad\_TooManyMonitoredItems" in a response so that this resolution comes up on search for people encountering the same issue.

Is there a way to see how many tags are on what tag group?

That fixed my issue

The tag report tool should be able to do that. Remember to also filter for OPC tags.

Well, I was able to add 40 more tags and then it stopped reading again. Any other suggestions? Before on our WinCC server we were reading 15000 tags but widdled that down to 4700. So, I'm not really sure.
