Event message lists
Event message lists allow you to view details of messages to help locate devices that are in an abnormal state.
When the system signals a status change, the control unit posts the event message in the appropriate event
message queue and generates a message list for the point that activated the event.
An event message consists of two lines of text, as shown in Figure 4 below. The first line displays the event type,
current status, and time of the event. The second line displays the message text, which is either the address of
the device that activated the event or, if programmed, a location description.
