7.9 Plant Event History
The Plant Event History screen is displayed in the round-robin queue on BST Manager units
only. It is similar to the unit Event History screen, in that it displays a list of events, however in
this screen, the events can come from any unit in the cascade, with the Unit ID column
indicating which unit the event occurred on, or Plant for plant level events such as
communication fault with BAS.
The Plant Event History screen displays the same layout, number of event and color coding as
the Unit Event History screen. However, plant-level events do not have additional details.
