Abstract
An automation protocol subscription service has a new SUBSCRIBE command with subscription bits that is sent from an automation controller to a master control switcher to indicate to the master control switcher to which items of configuration/status the automation controller is subscribing. In return when one of the subscribed-to items changes, the master control switcher returns a new SUBSCRIPTION command that indicates the change to the automation controller. In this way the knowledge of the configuration/status of the master controller is maintained at the automation controller.
