Multistate Alarms
The multistate alarm monitors a variable and triggers the alarm if the variable is between the configured alarm range or equal to a single value. You can add several ranges or single values to trigger the alarm.
Note:
The trigger values and the monitored variable must be integer.
Multistate alarm triggers an alarm when the monitored variable goes inside the configured range or a single value.
For example, you have a function block program with an output variable that generates integer values for different states. By using a multistate alarm, you can monitor a specific value or several value ranges.
You can configure multistate alarms using shunt variable and time delay. For more information, see Alarm Functions .
