● AlarmFunction [Simple(1), Basic(2), Extended Alarm(3)]
● AlarmClass [UrgentAlarm (1), HighPrioAlarm (2), NormalAlarm (3),
LowPrioAlarm (4), UserDefinedAlarm (5) and OffLineTrend (6)]
The notification class number is calculated as follows:
NotificationClass# := 10 * AlarmClass + AlarmFunction
This gives the following notification classes:
AlarmClass AlarmFunction Priority

To-Offnormal
To-Fault

Project-specific notification classes can be defined in addition to predefined
ones. Alarm classes 7...16 are intended for this purpose. The associated
calculation of a notification class number is identical to calculation of
predefined notification class numbers.
Customized alarms can be engineered in Desigo PX. In this case, the value for a
notification class number can be defined without restrictions.
