Description: Perform an operational change.
Purpose: This subroutine executes on a PC that is attempting to make an operational tag properties database change (i.e. a modification to the properties of a tag that are required for normal plant operation, but that is not subject to locking).
Format: EditLockoutManager\OperationalChange(TagName, ParmNum, ParmValues)
Parameters: TagName is the name of the tag to update.
ParmNumbers indicates the index of the parameter to change or the stream of indexes of parameters to change for TagName. These are assumed to be in increasing order.
ParmValues indicates the new parameter value or the stream of new parameter values to update for TagName.
Comments: An operational change is one that is required for normal operations, and as such must bypass the VTS locking scheme in the event that a connection to the server cannot be made and normal updates cannot be performed. EditLockoutManager\OperationalChange should be called from an active statement.
