For information about resizing objects, see page 20-45. For information about
assigning connections to objects, see page 20-31. For information about assigning
animation to objects, see Chapter 22.
To specify default link properties for reference objects
1. On the Edit menu, select Global Object Defaults.
2. Specify the new default values.
3. Click OK.
The defaults are used for any new reference objects you create. You can still edit the
properties for individual objects separately.
To break the link to a base object
 Right-click the reference object, and then click Break Link.
The reference object becomes a regular object. You can edit all of its properties.
However, you cannot restore the connection to the base object.
Delete the base object
If you delete a base object or a global object display containing base objects, any
reference objects that are linked to the deleted base objects are broken. A broken
reference object is displayed as a red square with an X through it. You cannot edit
broken reference objects.
To repair a broken reference object
 Recreate the base object with the same object type and name as before, on the same
display as before.
Use global object parameters
Global object parameters are parameters that you can assign to global objects. You can use
a global object parameter to assign different tags or sets of tags to each reference object
without breaking the link to the base object. You can then make changes to the base object
and all the associated reference objects at the same time.
Use global object parameters when more than one instance of a global object is used on a
display. For example, the Logix_PIDE global object display contains a grouped object
composed of other grouped objects. The objects’ connections are set up with tags and
expressions that use values from a set of Logix5000 tags. When you create multiple
reference objects from this base object, each reference object can use a different set of
Logix5000 tags. The global object parameters you assign to the base object allow you to
do this, because you are using a placeholder instead of a specific backing tag (a backing
tag is a path to a folder of tags; it is also known as a structured tag). If you then change,
