Summary:
Question:

The 'Alarm ON Action' Cicode is called when an alarm in the associated category is tripped. If several alarms are tripped in the category on the same alarm scan, the ON Action Cicode is called only once. This optimises the calling of the Cicode. For example, if 100 alarms were tripped at the same time, Citect will only call the ON Action once, not 100 times. (If the Cicode was called 100 times it would generate a large CPU overload.) We have also found in the past that this function is used mostly to sound an alarm or other similar operation that should only be called once per alarm process.

The 'Alarm OFF Action' Cicode is called in a similar way. 


Solution:
If you want some action to happen when a particular alarm occurs, put that alarm in a category of its own. Or put the Cicode into a report and make the trip Cicode the same as the alarm.
