examining the ComponentApp objects and can launch the plug-in using the RegisteredServer
property:
• Plug-in commands to be used by all networks are listed in the ComponentApps collection
in the ObjectServer object.
• Plug-in commands that are specific to a network are listed in the System objects.
• Plug-in commands that are specific to a device type are listed in the DeviceTemplate
objects.
