PROBLEM TO BE SOLVED: To provide a method for transmitting inverted two-consecutive transmission data which automatically makes exclusively ORing in the presence of inverted two- consecutive transmission data and checks the result so as to reduce the opportunities of setting errors and decease a setting load for the presence/absence of inverted two- consecutive transmission data. SOLUTION: Only a transmitter side controller (A) sets the presence/absence of inverted two-consecutive transmission data, a receiver side controller (B) discriminates the presence/absence of inverted two-consecutive transmission data on the basis of received data, calculates exclusive OR of the received data in the presence of inverted two-consecutive transmission data, discriminates the received data to be normal when all bits are logical 1, or discriminates the received data to be abnormal in other cases, and calculates no exclusive OR in the absence of inverted two-consecutive transmission data. Thus, having only to set the presence/absence of inverted two-consecutive transmission data to only the transmitter side controller can allow the receiver side controller to automatically discriminate the presence/absence of inverted two-consecutive transmission data and to calculate the exclusive OR in the presence of inverted two- consecutive transmission data.
