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.
注释：
The trigger values and the monitored variable must be integer.
图：
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. 有关更多信息，请参阅 Alarm Functions .
