Event message queues
The EST3X control panel dynamically maintains 1,000 most recent, highest
priority event messages across the four queues. An individual queue can hold
999 messages. The queues display at the bottom of the event message screen
(see Figure 5).
The event message queues allow you to view details of messages to help locate
points that are in an abnormal state. When the system signals a status change,
the control panel posts the event message for the point that activated the event
into the appropriate event message queue.
