# LinkBaseObject or (GroupLinkBaseObject)

Shows the location and name of the base object or group to which the reference object is linked. This property is read-only, and cannot be edited by the user.

All reference objects, except objects that are part of a grouped reference object, will have this property. For grouped reference objects, the property in the property panel is called GroupLinkBaseObject.

The syntax is:

`DisplayName.BaseObjectName`

For example, if a momentary push button object named Button1 on a global object display called Main, is the base object for a reference object, this would appear as the value for the reference object's LinkBaseObject property:

`Main.Button1`

Tip: | If the display name does not match the name of a display in the application's, or HMI server's, Global Displays folder, or if the object name does not match one on the display, the link between the base and reference global objects will be broken. If you delete the base object and create another with the same name but with a different object type, the link between the base and reference global objects will be broken.
