Abstract

PURPOSE:To eliminate the need for the addition of address to each slave device, by transmitting data blocks provided with a plurality of data in a prescribed bit number serially with a prescribed period to a transmission line in which a plurality of slave devices are connected in series with a master device. CONSTITUTION:The data of a master device 1 is transmitted in series with N sets of slave devices 21-2N via one line 3 between a transmission terminal 1a and a data reception terminal 1b. A data block 41 consisting of serial arrangement of data 1R-NR sequentially from the master device 1 to each slave device is transmitted, and each slave device fetches a data at the head when the data block 41 passes through and the data given to the master device 1 is added to the final end of the data block.
