A new log entry is created for each change in a particular status, including changes to a server latch or alarm acknowledgment.

It is possible to query the log database for specific acknowledgment or latch events. The Alarm state area of the log viewer has an Extra field that enables searching for additional state information. For example, the text value of a button that was acknowledged in iC Web could be typed in the Extra field. The query results obtained might provide valuable information about the acknowledged channel ID.
