Partially documented class in the Logix5000 Data Access Programming Manual that supplies information on changes to the controller that invalidate cached tag and template information. This class in a real controller does not support Get_Attribute_Single, but does support Get_Attribute_List for all of the attributes revealed by Get_attribute_All.

public LgxDevice getDevice()
```
    Description copied from class: CipObject
    
    CipObjects are expected to be organized as a tree, typically with a CipDevice at the root. (CipDevices can have a parent too, if an implementer chooses to represent a virtual chassis that way.)
    By default, any CipObject will simply ask its parent for the device if asked for the device. A CipDevice returns itself.
    
    Overrides:
    
    getDevice in class CipObject
    
    Returns:
    
    The CipDevice found in the parents of this object, if any.
