Communication protocol system and method for a distributed architecture heating, ventilation and air conditioning network
First Claim
1. An HVAC data processing and communication network, comprising:
- a system device comprising;
a physical layer interface configured to interface to a data bus;
a local controller configurable to send and receive messages over said data bus via said physical layer interface; and
wherein said messages include a first class of messages that address said system device using only a device designator of said device, and a second class of messages that address said system device using a message ID formed from a portion of said device designator and a non-zero offset.

Abstract
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.
