Is it possible to configure a graphic element to have no reference to its parent object?
I am using the 800xA tabbed navigation workplace and I want to display the same object (motor/valve/transmitter) on several displays in different tabs. However, I only want the object to reference to one of the displays. On the other displays the object should just indicate status/value etc.
So far I'm using elements from the graphic toolbox and I'm pointing to the objects to change colors etc.
Is it possible to configure a graphic element aspect (inside the object) in a way that removes the reference to the object itself so I can drag and drop this element in the graphics builder?
A graphical element need to refer to a Control Connection Aspect (called Function Block, Control Module or Application in AC800 Connect) to be able to subscribe to OPC data.
Graphic elements are normally created on the object also having the CCA aspect, but I believe elements may also refer to a child's CCA (but not the opposite) when using Composite Object Types.
I'm not quite sure what the problem of having multiple references to the same object would be in your use case?
Multiple references are not a problem to the system - but each will be shown with a separate line in the References... submenu of the object's context menu.
If possible, try to add some more description.
Also, stay out from making use of so called "Late Binding" in your attempts to avoid having a direct data reference to the CCA. Late Binding may seem tempting, but comes with a lot of overhead which causes display exchange performance to drop.
