摘要： A system has a plurality of nodes communicating with each other on a serial data path using dominant and recessive signal levels. A dominant signal level sent on the data path by any of the nodes creates a dominant signal level on the data path irrespective of the number of recessive signal levels sent by other nodes. The dominant and recessive signal levels form a series of bits organized into messages by the nodes. Each sending node senses the signal level on the data path bit by bit, and if different from that sent by that sending node, halts further sending of signal levels by that sending node. A priority value generator in each node provides a priority signal encoding a value whose magnitude indicates a relative priority. A message priority module in each node receives the priority signal, and stores the priority value in predetermined leading bits of the message to be sent.

摘要： A method of communicating between a plurality of devices in a controller area network is disclosed. The method includes authorizing a first device to transmit messages with a first identifier over the network, the first device transmitting a first message with the first identifier and a first value, and the devices which receive the first message assuming the first value as their respective values. The method may be used with a number of devices and a listening device in a system. At startup of the system, any device which saved its value in a non-volatile memory will become the master of the identifier and transmit a message with the value over the network. Devices which did not save their values in non-volatile memories will transmit requests for the data value. If they do not receive any response, they will become the master and transmit messages with their data. Devices which receive the message will assume the value as theirs. If the value at a device is changed, that device will become master and transmit a message with its value.

摘要： An autodiscovery system for configuration information about an HVAC system being provided to a controller or thermostat. Configurations or parameters may be autodiscovered from communicating equipment. Also, this equipment may be manually selected and set without affecting the autodiscovery status of the remaining equipment. There may also be non-communicating equipment that does not provide information to the thermostat. However, the thermostat may control the non-communicating equipment via an equipment interface module.

摘要： First and second serial data busses are arranged so that simultaneous transmission on the respective bus of a dominant state by one node and a recessive state by other nodes results in the dominant state being detectable on the respective bus. Transitions from a first state to a second state signal the start of a bit on the first bus. Dominant and recessive states are detected on the first and second busses at first and second predetermined times after each transition. The states represent respective dominant and recessive bits of attempted messages transmitted by nodes of the first and second busses. The dominant state is transmitted on both busses after the first and second predetermined times if the dominant state was detected on one of the first and the second busses at the first and second predetermined times.

摘要翻译：系统具有使用显性和隐性信号电平的串行数据路径上彼此通信的多个节点。任何节点在数据路径上发送的主要信号电平在数据路径上产生主要信号电平，而与其他节点发送的隐性信号电平的数量无关。显性和隐性信号电平形成由节点组织成消息的一系列位。每个发送节点逐个地检测数据路径上的信号电平，并且如果与该发送节点发送的信号电平不同，则停止该发送节点进一步发送信号电平。每个节点中的优先级值生成器提供对幅度指示相对优先级的值进行编码的优先级信号。每个节点中的消息优先级模块接收优先级信号，并将优先级值存储在要发送的消息的预定的前导位中。
