PROBLEM TO BE SOLVED: To make the transmission rate of a communication system faster by improving the efficiency of effective transmission of the system, even when the system is not able to detect collisions and adopts a one-to-N communication system. SOLUTION: The communication system adopts such a data communication system, that logically forms a master node and N (N: a natural number of 2 or larger) pieces of slave nodes on a bus-type network and discriminates whether or not transmitted data are received by the recipient of the data, based on reception confirming data returned from the recipient. When the master node transmits individual data D1-D3 to the slave nodes, the master node makes control to successively generate the header, data D1, and EOF for transmitting the data D1 to one slave node and, thereafter, to repeatedly and successively generate the header information IDs peculiar to the remaining slave nodes in connection with the generated EOFs, the data D2 and D3, and EOFs to the remaining slave nodes for transmitting the data D2 and D3 to the remaining slave nodes.
