After you set up an alarm to show as a tag, you can select the alarm in the Tag Browser,
and then select the alarm tags you want to use. For more information, see “Using tags to
interact with alarms or obtain their status” on page 12-51.
Alarm status tags
Alarm status tags let you use handshaking to keep alarm state changes synchronized with
a controller (PLC-5 or SLC 500).
For example, if an Acknowledged status tag is specified for an alarm, when an operator
acknowledges the alarm, the status tag is set to 1.
You can use status tags to handshake changes in the In Alarm, Disabled, Suppressed, and
Acknowledged alarm states.
To assign status tags to tag-based alarms, in the Alarm and Event Setup editor, select the
Status Tags tab in any of the Digital, Level, or Deviation Properties dialog boxes. For
more information, see page 12-27.
Alarm messages
Alarm messages report information about alarms.
For each alarm condition, you can create a message (or specify an existing message) to
display when the alarm condition occurs. You can also use placeholders and insert
variables in alarm messages.
To create and modify tag-based alarm messages, in the Alarm and Event Setup editor,
select the Messages tab or open any of the Digital, Level, or Deviation Properties dialog
boxes. For more information, see “Setting up tag-based alarm messages” on page 12-28.
Alarm audit, diagnostic, and history logs
FactoryTalk Alarms and Events generates three types of messages for logging:
Audit messages
are generated in response to actions performed in alarm and event
objects, such as modifying or acknowledging an alarm.
