1. A method of manufacturing an HVAC data processing and communication network, comprising:
- configuring a first system device to send and receive messages over a data bus;
configuring a second system device to send configuration data associated with a configuration of said second system device to said first system device;
configuring said first system device to receive and persistently store said configuration data, wherein said stored configuration data is historical configuration data of said second system device;
configuring a controller of said HVAC data processing communication network to determine if current configuration data of said second system device is flawed based on a comparison to said historical configuration data by comparing said historical configuration data to said current configuration data; and
configuring said controller to initiate a routine for correcting said current configuration data when determining said current configuration data is flawed.

Abstract
The disclosure includes an HVAC data processing and communication network and a method of manufacturing the same. In one embodiment, the HVAC data processing and communication network includes a first system device and a second system device. The first system device is configured to send and receive messages over a data bus. The second system device is configured to send configuration data associated with a configuration of the second system device to the first system device. The first system device is further configured to receive and persistently store the configuration data.

9. An HVAC data processing and communication network of an HVAC system, comprising:
-
a first system device configured to send and receive messages over a data bus; a second system device configured to send historical configuration data associated with a configuration of said second system device to said first system device; wherein said first system device is further configured to receive and persistently store said historical configuration data; and a controller configured to compare said historical configuration data to current configuration data of said second system device to determine differences therebetween and initiate a routine to correct said differences when present, said controller further configured to publish restore messages to said data bus directing said first system device to publish said historical configuration data to said data bus, and directing said second system device to recover said configuration by receiving said historical configuration data. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An HVAC data processing and communication network subnet controller of an HVAC system, comprising:
-
a physical layer interface configured to interface to a data bus of an HVAC data processing and communication network; a local controller configured to determine if historical configuration data of a second device of said HVAC system differs from current configuration data of said second device, wherein said historical configuration data is stored on a first device of said HVAC system, said local controller further configured to cooperate with said physical layer interface to publish a message via said data bus directing said first system device to publish said historical configuration data to said data bus when determining said current configuration data differs from said historical configuration data. - View Dependent Claims (17, 18, 19)
