Alarm classes
Alarms are assigned to various alarm classes:
●
Error
Alarms in this class must always be acknowledged. Alarms normally indicate critical
errors within the plant such as "Motor temperature too high".
●
Warning
Warning alarms usually indicate states of a plant such as "Motor switched on".
●
System
System alarms indicate states or events which occur on the HMI device.
●
User-specific alarm classes
The properties of this alarm class must be defined in the configuration.
Further information on this may be available in your plant documentation.
Alarm buffer
Alarm events are saved to an internal, volatile buffer. The size of this alarm buffer depends
on the HMI device type.

Alarm window
The layout and operation of the alarm window correspond to that of the alarm view.
The alarm window is independent of the process screen. Depending on the configuration,
the alarm window appears automatically as soon as a new, unacknowledged alarm has been
received. The alarm window can be configured so that it only closes after all the alarms have
been acknowledged.
Additional information on this may be available in your plant documentation.
