LinkBaseObject or (GroupLinkBaseObject)
All reference objects except objects that are part of a grouped reference object, will have a LinkBaseObject property. The LinkBaseObject property displays the location and name of the base object to which the reference object is linked. This property is read-only, and cannot be edited by the user.
When using this property, note that:
- 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.
- To restore the reference object, you must recreate the global object with the same name, on the same global object display.
- If the LinkBaseObject property for a reference object, points to a base object that no longer exists or is unavailable, the reference object is replaced by a red X on a white background.
- 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, which is 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.
