Variable Status Alarms

The variable status alarm monitors the status of a variable. The alarm is triggered when the value of the monitored variable is either forced, overridden or offline. If you configure the alarm to trigger on all statuses, the alarm is triggered immediately when the variable changes to one of the statuses.

The override status indicates that the value of a variable is adjusted by the I/O hardware, and is not the measured value. Für weitere Informationen siehe Output Override Status .

The force status indicates that the value of a variable is adjusted by the software, and is not the measured value. Für weitere Informationen siehe Schaltflächen softwareübersteuern und Softwareübersteuerung aufheben .

The offline status indicates that the status of the monitored variable is offline.

For example, you can use the variable status alarm to get a notification when a technician overrides the variable on an I/O module.

You can configure the variable status alarms using shunt variable and time delay. Für weitere Informationen siehe Alarm Functions .
