Alarm Reporting In Runtime
An alarm condition which occurs during runtime is brought to the attention of the operator. There are
a variety of options available in the way alarms are reported. These options are configured in the
development environment. During runtime, there are essentially four ways of examining alarm
messages: the Alarm Acknowledge dialog, the Current Alarm dialog, the Alarm History dialog and
the Alarm Object.
The Alarm Object is a graphical object which displays alarm messages in a similar way to the alarm
status viewer. Refer to chapter 4, Objects for an explanation of how to configure an alarm object to
filter alarm messages by group name.
Alarm Acknowledge
Whenever an alarm is raised during a runtime application, a confirmation dialog is optionally
displayed requesting acknowledgement of the alarm. The dialog shows the alarm message, priority,
and the date and time the alarm was raised. Click the Acknowledge pushbutton to close the dialog.
Alarm messages are queued so that as each message is acknowledged, the next in the queue becomes
visible. If a new alarm occurs which has higher or equal priority the details are updated to show this
newer/more important alarm first. The dialog disappears when there are no further alarm messages to
be reported. Each acknowledgement is logged in the alarm history log with the login name of the
current user. An unacknowledged alarm does not affect a runtime application.
