About embedded variables
Use embedded variables to provide information in a graphic display that updates
dynamically at run time.
Embedded variables can contain the following elements:
 Tags
 Tag placeholders
 Literal numbers or strings
 The time and date
You can insert one or more embedded variables into the text captions on graphic objects,
tooltip text, local message text, and the title bar text of graphic displays.
For example, if you embed a tag value and a time variable in a local message, when the
local message is shown at run time, it will show the tag’s current value and the current
time. The variables will update whenever the tag’s value and the time change.
For more information about how embedded variables update at run time, see page 21-10.
You can also insert variables in the alarm messages you create for FactoryTalk alarm
definitions. For more information, see Chapter 12, Setting up FactoryTalk alarms.
