Abstract

PURPOSE:To reduce the data transmission interval between a slave station and a master station and to increase the communication speed, by having the slave station make data transmission exclusively with the master station successful in the polling and transmitting data to other master stations through the master station. CONSTITUTION:A polling instruction signal is outputted from an operation controller 4 of master stations Mi-Mj via a transmission interface 2, transmission line coupler 1 and transmission line DL and transferred to a slave station Sk. Further, in the slave station Sk, the polling instruction signal is transferred to a transmission interface 3 and the specified data stored in a transmission buffer 6 is transmitted to the master station Mi. Further, in the master station Mi succeeded in the polling, the data stored in a reception buffer 7 of the transmission interface 2 is moved to a transmission buffer 6 and the same reception data is transmitted to other master station Mj via the transmission line coupler 1 and the transmission line DL.
