Use the data source to interact with alarms
You can also set up remote acknowledgement, silencing, and resetting of alarms, to allow
the data source to perform these functions. And you can set up the data source to
determine which types of alarms to show (active, inactive, acknowledged, and
unacknowledged), and to close the alarm display. These topics are discussed later in the
chapter.
Methods for acknowledging alarms
A single alarm is acknowledged when:
 The operator selects an alarm in the alarm list and presses the acknowledge alarm
button, an enter button object, or the Enter key on an external keyboard or keypad.
 The alarm banner has focus and the operator presses the acknowledge alarm button.
A single alarm for a particular trigger is acknowledged when:
 The trigger’s Remote Ack connection value changes to the alarm’s trigger value (or bit
position, for bit triggers).
All alarms for a particular trigger are acknowledged when:
 The trigger’s Remote Ack connection value changes to the Acknowledge all value.
The Acknowledge all value is specified in the Use ack all value box in the Alarm
Setup editor.
 The operator presses an acknowledge all alarms button that is set up to acknowledge
the alarms for a specific alarm trigger.
All alarms in the alarm log file are acknowledged when:
 The operator presses an acknowledge all alarms button that is set up to acknowledge
all alarms.
 The Remote Ack All connection’s value changes to a new non-zero value.
For more information about acknowledging alarms, see page 9-38.
Methods for clearing and deleting alarms
Alarms are deleted from the alarm log file and cleared from all alarm lists and alarm
banners when the operator presses the clear alarm history button. You can set up the
button to clear alarms for all alarms, or for a specific alarm trigger.
The operator can send button presses to objects that do not have focus. For information about
linking buttons to objects, see page 21-9.
