Learn about top-down hierarchical configuration

The start time and end time transitions of the level 1 event frame (/Procedure/PIBatch) is driven by the level 1 active point configuration.

If a level 2 event frame (Unit Procedure/PIUnitBatch) changes to an active state while its parent level 1 event frame is active, the level 2 event frame is created as a child. If the level 1 event frame trigger changes to an inactive state, it ends the level 1 event frame and all its child event frames.

The following figure shows events occurring at levels one and two and the event frames that are generated as a result.

The following table lists event frames resulting from the events depicted in the figure.
