Hi JKSH,
Please take a look at the Help File for the Alarming Page of the shared variables, under alarms, the Deadband/Time option seems to be the one you are looking for:
Deadband/Time—Sets the Deadband or Time of the alarm.

Hi Steve,
The "Time" option only applies to "Rate of Change" alarms, i.e. trigger an alarm if the variable changes by a magnitude of Change (or more), within a period of Time.
I'm looking for a way to trigger an alarm if the variable exceeds a level for more than a specified period, but not if it exceeds that level for only a short instant.
