4. Alarm pages

An alarm page has the same characteristics as an application page with regard to :

- the text,

- the fields.

The additional feature of an alarm page is its event-triggered display. The control system's word bit is assigned to each alarm page. If the word bit is at state 1, the page is displayed.

Ex.

A sensor fault occurs. The bit associated with the sensor fault changes to 1 in the control system.
