[Alarm]SummaryMode

  • Last UpdatedJul 19, 2023

Specifies how the alarm system commits timeout alarm summary entries into Summary Device.

Note: This parameter can also be applied to a specific cluster or alarm server process. For more information, see Configure Alarm Parameters for a Specific Cluster or Process.

Allowable Values:

  • 0 or 1: An alarm summary entry is timeout if the Off time is set, and the length between its On time and the current time is greater than the value of the parameter [Alarm]SummaryTimeout.

    If an alarm summary entry is not timeout, the uncommitted entries of which On time are newer than the On time of this entry will not be committed to log.

    In these two modes the alarm system usually logs alarm summary entries into Summary Device in the order they went ON. The order may break if a delayed alarm with an old timestamp is generated, or if an alarm summary entry is appended or split with an old timestamp.

  • 2 or 3: An alarm summary entry is timeout if the Off time is set, and the length between its Off time and the current time is greater than the value of the parameter [Alarm]SummaryTimeout.

    In these two modes the alarm system does not guarantee the order of On time or Off time of the entries which are committed into Summary Device, but instead attempts to commit timeout entries to Summary Device as soon as possible.

Note: Modes 0 and 2 no longer remove alarm summary entries from the summary page.

Default Value:

0
