PROBLEM TO BE SOLVED: To provide a data exchange method that can relieve a load onto a bus. SOLUTION: A subscriber transmits a message including data via a bus system, a 1st subscriber uses a function as a timing generator to temporally control a reference message having time information with respect to a time base of the 1st subscriber so as to be repetitively sent via a bus at a preset time interval, at least a 2nd subscriber uses the time base to generate its own time information in response to the time information of the 1st subscriber, obtains a correction value on the basis of the time information of the 1st subscriber and the time information of the 2nd subscriber, and the 2nd subscriber matches the time information and/or the time base of itself depending on the correction value. |
