Concept
Single Acknowledgement
When you select the acknowledgment type Single acknowledgment, the user needs to acknowledge the alarm in the alarm view before the alarm returns to normal state and disappears from the alarm view.
If the user acknowledges the alarm when it is in alarm state, the alarm is set to acknowledged state. When the problem that triggered the alarm is corrected, that is when the monitored variable no longer meets the criteria to trigger the alarm, the alarm returns to normal state.
Single acknowledgement loop where the alarm is acknowledged in alarm state
If the user did not acknowledge the alarm when it was in alarm state, and the monitored variable no longer meets the criteria to trigger the alarm, the alarm is set to reset state. The user needs to acknowledge the alarm in reset state to make it return to normal state. In this case, the alarm can toggle between alarm state and reset state several times before a user acknowledges the alarm.
