PROBLEM TO BE SOLVED: To provide a method for temporally making circular transmission of data to a bus with which a data transmitter for circularly and repeatedly transmitting data, and a data receiver are connected without generating bursts. SOLUTION: A cycle time TC is assigned to a data transmitter, and the data transmitter periodically transmits a data value PV, and a delay time TV related to the start of the cycle time of the data transmitter is assigned to each data value. Then, synchronizing information, having a phase position specific to a data transmitter having a cycle equivalent to the cycle time of the data transmitter related with the start of the minimum cycle time is transmitted, and the synchronizing information is received, and the transmission of the data value can be triggered with each delay time. Also, a monitor time which depends on the cycle time is fixed in a data receiver, and them the data value can be received. |
