This event occurs when all subscribed data tags have intialially received good quality data values.

This event only occurs once. It will only occur again if ALL data tags are unsubscribed and re-subscribed. In other words, this event will only happen once in the lifetime of an HMI display, unless the HMI display exits runtime mode and then subsequently re-enters runtime mode (if only a subset of tags are unsubscribed/re-subscribed, this event will not be raised).
