Abstract
A method of communicating between a plurality of devices in a controller area network is disclosed. The method includes a first device transmitting a first message over the network, a second device comparing a first value in the first message with a second value, and a third device responding to messages it receives over the network. The method may involve a number of producer devices and a consumer device. The consumer device responds to messages sent as instance zero. The method may involve a number of producer devices, an intermediate consumer and a consumer device. The producer devices send their messages as instances other than zero. The intermediate consumer receives the messages from the producer devices, compares them, and sends messages as instance zero to the consumer device. The producer devices may be thermostats, actuators, sensors, etc. The consumer device may be a furnace, an air conditioner, etc.
