A refrigeration system including a compressor, condenser, valve, and evaporator in fluid communication; a system controller operable to control one or more aspects of the refrigeration system, and a subsystem controller in communication with the system controller. The subsystem controller is operable to control one of the compressor, condenser, valve, and evaporator. A method of operating the refrigeration system includes communicating a code from the subsystem controller to the system controller, obtaining information at the system controller having a relation to the code; and communicating at least a portion of the obtained information from the system controller to the subsystem controller.
