In the upper illustration, the Event Logger watches for any of the three events
configured to cause a change of state to the Trip 1 DDE Item. None of these three
events have occurred, so the status of the Trip 1 DDE Item is at OFF. The
Annunciator Panel wizard is monitoring the configured DDE Items at the Event
Logger, but all DDE Items are “OFF” so the Annunciator Panel displays green
indicator tiles.
In the lower illustration, the Event Logger has recorded a “Trip” event for the unit in
question, and changed the state of the Trip 1 DDE Item to “ON”. The Annunciator
Panel wizard sees this chang e, an d responds by changing the color of th e ann unciator
panel tile for Relay 1 to red.
