Abstract

PURPOSE:To enable instant data retransmission at failure of reception, by using line mode of full duplex system and transmitting the result of reception data information error detection at a slave station to a master station quickly. CONSTITUTION:A signal inputted from a transmission line 1 to a slave station reception section 46 is stored in a reception register 45 via a slave station address comparator 42. A slave station transmission section 57 operates a transmission control circuit 54 with a signal of synchronizing signal detection and address coincidence at the reception section 46, and by the control of the circuit 54, a synchronizing signal forming circuit 51, slave station address output circuit 52 are driven and the content of a transmission register 55 is transmitted to the master station. Simultaneously, the result of detection of an information error detection circuit 43 of a reception signal is transmitted from an information error output circuit 53 to the master station via the transmission control circuit 54 while the master station outputs synchronizing signals to the slave station. If the information of data error comes from the slave station, the master station retransmits the same data frame to the slave station.
