Figure 83 Alarm
Boxes configured as alarms perform user warnings on anomalous events. For
this purpose, boxes of this type are related to a binary object ([Pn][Bi] Alarm
Trigger) that permits receiving alarm messages from the bus, thus making
Z41 Pro emit a continuous beep while the screen light blinks. In addition, the
screen will automatically browse to the page containing the alarm box that has
been triggered. After that moment, pressing on the “Menu” button will interrupt
the beeps and blinks although the box will still show an intermitting icon, which
means that the alarm is still active and unconfirmed. Additionally, the icon of
the page that contains the box will also show an exclamation.
Figure 84 Alarm (Box).
The intermitting exclamation means that the alarm is active and unconfirmed.
However, alarm boxes implement an additional binary object, [Pn][Bi] Alarm
Confirmation, intended for receiving the value “1” from the bus, which will be
interpreted as an acknowledgement of the alarm, thus making the icon
intermittence stop. Alternatively, the alarm can be acknowledged (and muted)
by touching on the “OK” button in the box itself, which will cause the sending
of the value “1” through the mentioned object.
The alarm will definitely become inactive once it has been confirmed and, in
addition, once the [Pn][Bi] Alarm Trigger object goes back to the “no alarm”
state (the order of these two events is irrelevant), after which the icon will
finally turn off.
