The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In an embodiment, the network includes a first subnet controller and a system device. The first subnet controller is coupled to a data bus and configured to arbitrate with a second subnet controller for control of the subnet. The system device is configured to transition from a reset state to a first state that includes pre-startup tasks, and transition from the first state to a second state that includes waiting for the subnet controller to provide configuration parameters to the system device.

1. An HVAC data processing and communication network, comprising: a data bus having a plurality of HVAC devices coupled thereto, forming a subnet; anda first subnet controller integral with a system device of said plurality of HVAC devices and configured to transition from a reset state to a first state that includes pre-startup tasks, transition from said first state to a second state that includes arbitrating with at least a second subnet controller coupled to said data bus to determine an active subnet controller for controlling said subnet, and transition from said second state to a third state that includes operating as said active subnet controller or as a passive subnet controller of said subnet based on said arbitrating, wherein said first state further includes sending start-up messages to at least some of said plurality of HVAC devices and said third state includes waiting for configuration parameters from said active subnet controller when operating as said passive subnet controller. 2. The network as recited in claim 1, wherein said system device is configured to transition from said first state to a hard disable state in the event that said system device receives a hard disable message via said data bus. 3. The network as recited in claim 2, wherein said system device is configured to transition from said hard disable state only to said reset state in response to receiving a message from a user interface via said data bus. 4. The network as recited in claim 1, wherein said pre-startup tasks include waiting in a listen-only mode for a predetermined period before publishing a device startup message to said data bus. 5. The network as recited in claim 4, wherein said system device is a first system device, and said pre-startup tasks include monitoring said data bus for a message indicating a second system device failed to properly receive said device startup message. 6. The network as recited in claim 5, wherein said first system device is configured to resend said device startup message after a delay based on a device designator in the event that said second system device failed to properly receive said device startup message and to republish said device startup message in the event that said first system device receives said message indicating said second system device failed to properly receive said device startup message. 7. The network as recited in claim 1 wherein said arbitrating includes considering factors unrelated to features and capabilities of said first subnet controller and said at least second subnet controller. 8. A method of manufacturing an HVAC data processing and communication network, comprising: coupling a first subnet controller to a data bus having a plurality of HVAC devices coupled thereto and forming a subnet, wherein said first subnet controller is configured to transition from a reset state to a first state that includes pre-startup tasks, transition from said first state to a second state that includes arbitrating with at least a second subnet controller coupled to said data bus to determine an active subnet controller for controlling said subnet, and transition from said second state to a third state that includes operating either as said active subnet controller or as said passive subnet controller of said subnet based on said arbitration, wherein said first subnet controller is integral with a system device of said plurality of HVAC devices; andwherein said first state further includes sending start-up messages to at least some of said plurality of HVAC devices and said third state includes waiting for configuration parameters from said active subnet controller when operating as said passive subnet controller. 9.

The system device as recited in claim 15, wherein said local controller is configured to transition from said first state to a hard disable state in the event that said local controller receives a hard disable message via said data bus. 17. The system device as recited in claim 15, wherein said pre-startup tasks include waiting in a listen-only mode for a predetermined period before publishing a device startup message to said data bus. 18. The system device as recited in claim 15, wherein said local controller is configured to transition to a soft disabled state in response to a first message received via said data bus. 19. The system device as recited in claim 18, wherein said local controller is configured to transition from said soft disable state to said first state in response to receiving a second different message via said data bus. 20.
