Alarm triggers and trigger values
You specify the tags and expressions (also known as connections) to monitor for alarm
conditions by creating an alarm trigger for each connection.
Each alarm trigger can generate one or more alarm messages, associated with different
trigger connection values. For each alarm trigger, you specify the trigger values that will
generate alarm messages, and create the messages to show for the trigger values.
The trigger value can be a non-zero integer value or a bit position, depending on which
trigger data type you assign. For more information about trigger data types, see page 9-11.
Filter alarm triggers in multiple languages
FactoryTalk View 5.00 and later supports alarm triggers in multiple languages. When you
create an alarm trigger, its name is in the current application language. You can export
alarm triggers for translation and then import them back into the application. For details,
see Chapter 12.
Various graphic objects allow you to specify the alarm triggers, to which the object’s
action applies, using the name of the alarm trigger. This is called filtering alarms. When
you translate trigger names into other languages, the default language is used to show the
trigger name in the object’s selection list. These graphic objects allow you to specify
alarm triggers using a selection list called the Trigger Label Selector:
 Alarm list
 Alarm status list
 Alarm banner
 Clear alarm history button
 Acknowledge all alarms button
 Print alarm history button
 Print alarm status button
If the trigger label name has not been set up in the default language, the Trigger Label
Selector shows a question mark (?) instead of the trigger label name. To correct the
display, you must import the trigger labels for the default language.
You can also manually type in the trigger label names to use to filter alarms. If you
manually type in the trigger names, specify the names in the default language.
An alarm’s Trigger and Remote Ack settings should not be configured to use the same tag.
Doing so may cause unpredictable alarm acknowledgement behaviors.
