If the hold time is still in effect and the operator acknowledges a new instance of the
same alarm, the new acknowledgement is ignored.
 If the alarm list is set up to show unacknowledged alarms only, the alarm is removed
from the list. The highlight bar or cursor moves up to the next unacknowledged alarm,
unless it is already on the top unacknowledged alarm.
 If the highlight bar or cursor is on an acknowledged alarm when the operator presses
the acknowledge alarm button, the button press is ignored.
 The alarm is removed from the alarm banner.
Acknowledge all alarms
When the operator presses an acknowledge all alarms button, all unacknowledged alarms
in the system (or, optionally, for a specific alarm trigger), are acknowledged.
This is what happens when the alarms are acknowledged:
 For each alarm trigger, to which an “Acknowledge all” value is assigned, the specified
“Acknowledge all” value is sent to the trigger’s Ack connection. The value is held as
long as the operator presses the button, or for the hold time, whichever is longer. Then
the connection’s value is reset to 0.
If the “Acknowledge all” value is not assigned for a trigger, no value is sent to the
trigger’s Ack connection.
If the hold time for any alarm is still in effect and the operator presses acknowledge all
alarms, the button press is ignored.
 If the alarm list is set up to display unacknowledged alarms only, all acknowledged
alarms are removed from the list.
 The alarm banner is cleared.
Silence alarms
When the operator presses the silence alarms button, any audible signal triggered by an
alarm is silenced and the Silence connection is set to 1 for the hold time or for the duration
of the button press, whichever is longer. Then the connection’s value is reset to 0.
If the hold time for any alarm is still in effect and the operator presses silence alarms, the
button press is ignored.
The audio alarm indicator is available for applications running on personal computers
only.
