Alarm Delay

Delaying alarm outputs The alarm delay time (in seconds) is entered in the attribute "Alarm Delay". The alarm delay time determines how long an alarm condition must exist before an alarm is generated. Entering an alarm delay time of 10 seconds means that the limit value must be exceeded for at least 10 seconds before this datapoint generates an alarm. If the limit value lasts for only 7 second, then no alarm occurs.

Alarm Suppression

The attribute “Suppress Alarm” establishes whether or not alarm messages from the following alarm attributes should be suppressed:

•Operational status

•Min/Max. limit

•Maintenance alarm

•Interval counter

•Alarm Status

The following entries are possible:

	•	Off	Alarms not suppressed
	•	On	Alarms suppressed
Digital input example	In addition to a variety of other attributes, a digital input also has the "Operating
	Mode", "Alarm Status", and "Maintenance Alarm" attributes. If alarm suppression is
	activated for this datapoint, then no message is displayed during an operating mode
	change-over, or when changing into the alarm condition, or when reaching the
	maintenance alarm.
Suppression of system	The controller will not issue a system alarm when the alarm’s system alarm text
alarms (V2.04.xx or higher)	starts with an @ character.

Alarm Status (prior to V2.04.x)

Alarm monitoring In the case of a digital input or a pseudo digital point, the attribute "Alarm Status" specifies whether or not alarm monitoring is required.

The following entries are possible:

•Yes: Alarm monitoring is required

•No: Alarm monitoring is not required

When alarm monitoring is required, the alarm message occurs when the digital point changes from the active state to the passive state (alarm reached). An additional message is generated (alarm going) when the digital point returns to the active state

(see Fig. 6. Alarm status messaging)
