In the User "Guide for Device Fault Manager, Software Release 3.2", regarding events it is said that "When the event has been in the Cleared state for 20 minutes, it expires and is removed from the display.", and regarding alarms it is said "Alerts are moved to Cleared when their last active event has been in the Cleared state for 20 minutes. You can also clear an event manually".
I have been reading through the document, and it seems to me that events can only be manually cleared.
I would like to know if there is any kind of timeout or any other way to automatically move events to clear state after a period of time, just to prune unattended alarms from the display.
