Issue
Changes to public variables (PVR, PVI, PVB) in a Menta file on a live system are accepted by the database, but it seems that the actual controller is ignoring these changes, or not seeing them.
Environment
Vista Workstation
More commonly a Vista Classic Network, though it does apply to LNS
Cause
In the upper left-hand corner of the Workstation, there is a drop-down menu to select either Engineering or Operating mode. Engineering mode is used most often in a Vista Classic Network while adding or configuring new controllers. While in engineering mode, changes can be made to database values, but these changes will not be propagated down into the controllers.
Resolution
Change back to Operating mode.
