We’ve got several L306-ER (v30) devices running on the AB Logix driver and they have been for ~a year.
Yesterday I pulled the [Diagnostics] folder for each device into a tags folder and today when I came back, they are all Bad Quality. Pulling the folder out of the OPC-UA server and dropping them into the tags window will refresh the data and they will go good quality again. I expect that given time, they will return to bad quality?
The other tags I am polling from these devices don’t have this problem, curious if anyone has any insight as to what’s happening. I don’t mind deleting them all and pulling them back in to try to resolve / replicate the issue, just wanted to run it by the community, first.
