  • Publication number: 20070268835
    Abstract: A control unit for transmitting data to control the operation of a controlled unit transmits a command via a main control channel and a sub control channel. The controlled unit distinguishes via which channel of the main control channel and the sub control channel received data is received and determines whether received data maintains a constant value for a predetermined period of time or not. When it is determined that the received data maintains a constant value, data for distinguishing a channel via which data is received and data indicating that a failure has occurred in a channel are transmitted to the control unit via the other channel. Receiving data indicating that a failure has occurred, the control unit outputs data indicating that a failure has occurred to the outside, and transmits subsequent data using the sub control channel when a failure has occurred in the main control channel.
