Warning Message: "No scan class information found for tags. All returned data will be bad quality."

Hi everyone.

Today I deleted a few objects containing history-enabled tags. Now I have the warning message “No scan class information found for tags. All returned data will be bad quality.” every second or so.

I read one post in the forum from 2012 about this issue. I’d like to know how to remove those deleted references so this warning will no longer appear in the system’s log. Or, is it going to disappear automatically soon?

Thanks for your help.

Well, we didn’t really found the problem, but discovered that one analog member of the object was causing it. Changed the object type to memory and then removed the history part of that tag. Problem “solved”.
