Abstract

See full text

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.
