Just curious, how exactly are you accomplishing this? I ask because if it's with a bi-directional transaction group as DB wins, I have found this doesn't work. If you were to download to the PLC, those values in the PLC will overwrite the DB, even if DB is set to win.
Python > Transaction groups
I put the line configuration screen behind a plant management user role in Ignition, and whenever a line setting is changed, the setting gets written to the corresponding row and column in a SQL table. When the PLC powers up, it automatically sets a "requestSavedSetpoints" flag. When Ignition sees this, it triggers a tag event script to push the saved SQL settings down to the PLC.
Transaction groups are handy, and have a lot of uses, but I have increasingly been using them less and less. They just aren't flexible enough to handle a lot of the things I've needed to do with SQL and PLC settings.
