Hello all, wondering if there's a simple way to detect when a tag's value has changed.
I have some tags whose values get updated every so often from an SQL query event I've created (DB is managed by another application). I would like to be able to notify the operator when the new DB value does not match the current value. I'm intending to tie a GUI object to this detection tag to show the user which values have changed.
Thoughts?
