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 change, and responds by changing the color of the annunciator panel tile for Relay 1 to red.
