Communication protocol system and method for a distributed architecture heating, ventilation and air conditioning network

摘要

The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In an embodiment, a system device configured for use in the network includes a physical layer interface and a communication module. The physical layer interface is configured to interface to a data bus. The communication module is configurable to send and receive messages over the data bus via the physical layer interface. The system device also includes a non-volatile memory configured to store configuration data. The messages include a first class of messages that address the system device using only a device designator of the device, and a second class of messages that address the system device using a message ID formed from a portion of the device designator and an offset.
