Modify a subnetwork controller

A subnetwork controller is a terminal on a device or junction object that represents the origin of a subnetwork, either a source or sink.

You can modify an existing subnetwork controller in the Modify Subnetwork Controller pane. The Subnetwork Name property can be changed for a subnetwork controller. When the subnetwork name is altered for a subnetwork controller, the existing subnetwork controller is deleted and a new controller is added with the new subnetwork name.

The Description and Notes properties are read-only for existing subnetwork controllers.
