Absolute reference syntax
When using absolute references:
 Precede area names with a forward slash (/). Also use forward slashes to separate area
names from other area names.
 Separate area names from component names with two colons (::).
Example: Absolute and relative references to tags in the same
graphic display
The graphic display named Detail, use in the previous examples, contains an absolute
reference to a tag named Speed in the AssemblyLineNorth area. The absolute reference is:
/AssemblyLineNorth::Speed
The display also contains a relative reference to a tag named Temp. The relative reference
is the tag’s name:
Temp
If you were to copy the Detail display to an area named AssemblyLineSouth, the display
would still look for the tag named Speed in the AssemblyLineNorth area, because it
contains an absolute reference to that tag.
However, the display would look for the tag named Temp in the AssemblyLineSouth area
because it contains a relative reference to that tag.
If the tag named Temp cannot be found in the AssemblyLineSouth area when the Detail
display is run, a FactoryTalk Diagnostics error will be logged.
Example: Using absolute and relative references with the Display
command
To create a button that an operator can press to open a display named Overview, use the
Display command in the button’s press action, in one of the following ways:
 To create an absolute reference to the display called Overview in the area called
Baking, type:
Display /Baking::Overview
 To create an absolute reference to the display called Overview in the area called
Packaging, type:
Display /Packaging::Overview
