For more information about creating global object displays, see Chapter 16, Creating
graphic displays.
Creating reference objects
After creating a global object (or group of objects), you can copy it for use in standard
displays throughout an application.
When you copy a global object into a standard graphic display (in the Displays folder), the
copy is called a reference object. The original global object (in the Global Objects folder)
becomes the copy’s base object.
Reference objects have special properties that link them to the original, base objects.
When you modify properties of a base object, the changes are copied to all reference
objects linked to the base object.
You can produce an unlimited number of reference objects from a single base object.
However, reference objects can only link to a base object within the same application or,
in a network distributed application, within the same HMI server.
To create a reference object
To create a reference object, use one of these methods:
 Copy a global object from a global object display into a graphic display in the same
application or, in a network distributed application, within the same HMI server.
 Copy an existing reference object from one graphic display to another in the same
application or, in a network distributed application, within the same HMI server.
 Add a global object display into the Displays folder in the same application or, in a
network distributed application, within the same HMI server. In this case, all objects
saved in the display are converted to reference objects.
To add a global object display into the Displays folder
1. In FactoryTalk View Studio, in the Explorer window, right-click the Displays icon,
and then select Add Component Into Application.
2. Browse to and select the global object display to be added, and then click Open.
If you add a global object display into the Displays folder in a different HMI server, the global
objects are converted to standard graphic objects, rather than reference objects.
