Hi all. Hope someone can point me in the right direction. I have a random analog tag that has stop working on Intouch. All the parameters look fine, tag seems to be configured the same as the other tags coming from the same PLC. What could cause a singular tag to stop working. Never used Intouch before so kinda just winging it. System is not standalone and communicating with a SLC 5/04.

 

Check your scaling in InTouch - if the PLC value is outside of the range, it may appear to not work.
