Create the macros in the Macros editor. Make sure you name them exactly as shown in the
right column of the preceding table (with no space in the name).
When the tag or expression assigned to one of these connections changes to a new non-
zero value, FactoryTalk View runs the associated macro.
For information about creating macros, see Chapter 30.
Set up backlight intensity remotely
For applications that will run on PanelView Plus 7 and PanelView Plus 6 terminals, use
the Remote Backlight Intensity connection in the Backlight tab of the Global
Connections editor to set the backlight intensity of a run-time terminal remotely from a
data source.
To update the backlight intensity of the run-time terminal from the data source, assign a
tag or an expression to this read-only connection.
At run time, the application reads the value at the data source and sets the backlight to the
percentage of its maximum intensity corresponding to the value. For instance, if the value
of the connection is 25, the backlight will be set to 25 percent of its maximum intensity.
This value will override the terminal’s own backlight intensity setting.
If the value of the connection is greater than 100, the backlight will be set to its maximum
intensity. If the value is less than 0, the backlight is set to its minimum intensity. That is, it
will be turned off.
Monitor run-time RAM usage
Sometimes it is helpful to monitor run-time RAM usage for troubleshooting purposes. If
your application seems to be running slowly, consuming too much memory, or interfering

Leave time for a macro to run before starting a new macro. Otherwise, FactoryTalk View will
queue the macros, which consumes memory and could lead to system instability. When you shut
down FactoryTalk View ME Station, if a message about executing macros is shown for more than
a few seconds this means that macros have been queued.
