Example: Using alarm tags to acknowledge an alarm
An operator is expected to acknowledge alarms associated with a faceplate in a graphic
display that does not contain an alarm and event summary or banner.
To let the operator acknowledge High High alarm conditions for the alarm, named
Level_Alm1, you might try the following these steps:
1. In the Alarm and Event Setup editor, open the Properties dialog box for Level_Alm1,
and then select the check box, Show Alarm as a Tag.
2. In FactoryTalk View Studio, open the graphic display that the operator will be
monitoring, and then create this text object:
High High Alarm
.
In the text object’s Properties dialog box, select red as the Fore color. Make the object
big enough to catch the operator’s attention when it becomes visible.
3. Right-click the
text object, select Animation > Visibility.
4. To make the
High High Alarm
object visible when a High High alarm occurs for
Level_Alm1:
In the Expression box, type Level_Alm1.HHInAlarm.
For the Expression true state, select Visible.
Level_Alm1 is a tag-
based alarm definition
exposed as a tag.
When you select the
alarm in the Tag Browser,
its alarm tags become
visible in the right-hand
window.
You can use the Oper*
tags to let an operator
respond to instances of
the alarm at run time.
