The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In an embodiment, the network includes a local controller. The local controller is configured to publish a first message to a data bus, and to detect a collision between the first message and a second message published to the data bus. The local controller is further configured to republish the first message in the event that the first message collides with a second message published to the data bus; a bit error results in response to publishing the message.
1. An HVAC data processing and communication network, comprising: a first local controller associated with an HVAC component, said HVAC component in communication with at least one other HVAC component via a data bus, said first local controller configured to:publish a first message to said data bus
1. An HVAC data processing and communication network, comprising: a first local controller associated with an HVAC component, said HVAC component in communication with at least one other HVAC component via a data bus, said first local controller configured to:publish a first message to said data bus;detect a collision between said first message and a second message published to said data bus; andrepublish said first message, after a delay unique to said first local controller, in the event that said first message collides with a second message published to said data bus by a second local controller and a bit error results as a result of said collision wherein said delay is derived from a device designator of said local controller and is determined by multiplying a base delay time by a factor based on a subset of bits of said device designator. 2. The network as recited in claim 1, wherein a first attempt to republish said first message uses a first contiguous subset of bits of said device designator, and a subsequent attempt to republish said first message uses a different contiguous subset of bits of said device designator. 3. The network as recited in claim 1, wherein said message is a device startup message configured to indicate that said first local controller is ready to operate in the network after a reset condition. 4. A method of manufacturing an HVAC data processing and communication network, comprising: configuring a first local controller associated with an HVAC component, said HVAC component in communication with at least one other HVAC component via data bus, to:publish a first message to a data bus, after a delay unique to said first local controller, said delay derived from a device designator of said first local controller;detect a collision between said first message and a second message published to said data bus;republish said first message in the event that said first message collides with a second message published to said data bus by a second local controller and a bit error results as a result of said collision; andconfiguring said first local controller to determine said delay by multiplying a base delay time by a factor based on a subset of bits of said device designator. 5. The method as recited in claim 4, further comprising configuring said first local controller to make a first attempt to republish said first message using a first contiguous subset of bits of said device designator, and to make a subsequent attempt to republish said first message using a different contiguous subset of bits of said device designator. 6. The method as recited in claim 4, wherein said message is a device startup message configured to indicate that said first local controller is ready to operate in the network after a reset condition. 7. A system device of an HVAC data processing and communication network, comprising: a demand unit configured to provide a service; anda first local controller configured to:control a level of said service;publish a first message to a data bus;detect a collision between said first message and a second message published to said data bus by a second local controller; andrepublish, after a delay unique to said first local controller, said first message in the event that said first message collides with a second message published to said data bus by said second local controller and a bit error results as a result of said collision, wherein said delay is derived from a device designator of said first local controller and is determined by multiplying a base delay time by a factor based on a subset of bits of said device designator. 8. The system device as recited in claim 7, wherein a first attempt to republish said first message uses a first contiguous subset of bits of said device designator, and a subsequent attempt to republish said first message uses a different contiguous subset of bits of said device designator.
