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.
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; andwherein said messages i
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; andwherein 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. 2. The network of claim 1, wherein said messages in said second class include a message identifier, and said offset is said message identifier. 3. The network of claim 1, wherein said local controller is configured to accept from said data bus said first class of messages but not said second class of messages. 4. The network of claim 3, further comprising a non-volatile memory configured to store configuration data, wherein said local controller is configured to respond to said second class of messages after configuration data is written to said non-volatile memory. 5. A method of manufacturing an HVAC data processing and communication network, comprising: configuring a physical layer interface of a system device to interface to a data network;configuring a local controller of said system device to send and receive messages over said data network via said physical layer interface; andwherein 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. 6. The method of claim 5, wherein said messages in said second class include a message identifier, and said offset is said message identifier. 7. The method of claim 5, further comprising configuring said local controller to accept from said data bus said first class of messages but not said second class of messages. 8. The method of claim 7, further comprising configuring a non-volatile memory of said system device to store device configuration data, and configuring said local controller to respond to said second class of messages after configuration data is written to said non-volatile memory. 9. A system device of an HVAC data processing and communication network, comprising: a compressor, fan or blower;a physical layer interface configured to interface to a data bus; anda local controller configurable to send and receive messages over said data bus via said physical layer interface and to control an operation of said compressor, fan or blower in response to received messages,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. 10. The system device of claim 9, wherein said messages in said second class include a message identifier, and said offset is said message identifier. 11. The system device of claim 9, wherein said local controller is configured to accept from said data bus said first class of messages but not said second class of messages. 12. The system device of claim 11, further comprising a non-volatile memory, wherein said local controller is configured to respond to said second class of messages after configuration data is written to said non-volatile memory. 13. The network of claim 3, wherein said device is configured to accept said first class of messages while disabled. 14. The network of claim 1, wherein said local controller is configured to send a device startup message after a delay time computed from a contiguous subset of bits of said device designator. 15. The network of claim 1, wherein said portion is located adjacent to a transport protocol bit in a message ID field of said message. 16. The method of claim 7, wherein said device is configured to accept said first class of messages while disabled. 17. The method of claim 5, wherein said local controller is configured to send a device startup message after a delay time computed from a contiguous subset of bits of said device designator. 18. The method of claim 5, wherein said portion is located adjacent to a transport protocol bit in a message ID field of said message. 19. The system device of claim 9, wherein said device is configured to accept said first class of messages while disabled. 20. The system device of claim 9, wherein said local controller is configured to send a device startup message after a delay time computed from a contiguous subset of bits of said device designator.
