I’m running Ignition 8.0.9 and have an application that’s basically just acting as a data logger. I have multiple transaction groups storing OPC tags to a database that worked as desired when I first configured it. However, when I checked back later, the data stored for specifically one of my tags was stuck at 1064.375, even though the OPC tag it was pointing to was continuing to change. I double and triple-checked the configuration but could find nothing wrong.
I ended up deleting the OPC tag in the tag browser (despite it appearing to be fine and actively updating) and recreated an identical OPC tag with the same name/path. Having changed nothing in the transaction group setup, it then proceeded to work fine with the recreated tag.
Does anybody know what caused this and how it can be avoided in the future?
Thanks!
