Alarm Display - Omron NB Series Operation Manual

3-6-18 Alarm Display

The Alarm Display component will display all the alarm information enabled in the set area.
The content it displays is the same as that displayed by the Alarm Bar, and both of them are about the
alarm information of a certain node switch (bit address). When alarm information arises, it won't
automatically be cleared until this bit address is switched back to the non-alarm state. Before that, the
alarm information will persist, i.e. being in alarm state all the time. This component only displays the
alarm information, and the component to be displayed must be registered by the "Alarm Information"
database.
