The alarm summary timeout parameter is used to remove alarms from the alarm summary after a specified period of time. This parameter has a maximum setting of 20000 minutes. Periods longer than this are not supported. 

With this enhancement, the alarm summary timeout may be disabled. With the SummaryTimeout parameter set to -1 alarms will not be removed from the alarm summary based on a timeout period. Alarms will still be removed when the alarm summary grows beyond the number of alarms specified in the [Alarm]SummaryLength parameter.

The alarm summary timeout may be set by adding the following to your citect.ini file:


Where n may be -1 to disable the timeout or any value from 0 to 20000 representing the timeout period in minutes.



Sets the timeout period to 1 hour.

CIT has confirmed this to be a problem in Citect for Windows versions 5.XX. This problem has been fixed in version 5.40 Service Pack B.
