Abstract
PURPOSE:To increase amounts of data to be transmitted within a constant time, by reading out the data written by a master station from the data block of a data frame sent to a data transmission path by plural slave stations, and writing the data to be sent to the master station in the data block. CONSTITUTION:The master station 21 sets the data to be sent to each of the slave stations 22a-22n in each of the data blocks 27a-27n, and sends them to the data transmission path 23. A first slave station 22a, when receiving the data frame 25 sent from the master station 21, reads out the data in the data block 27a, and sets the data to be sent to the master station 21 at the data block 27a, and sends it to the data transmission path 23. Second-(n)th slave stations 22b-22n perform the same operations, respectively. In such a way, it is possible to increase the amonuts of transmission data within the constant time.
