Abstract

PURPOSE:To prevent the whole system from generating a fault by detecting a station generating a fault based on a data frame and a collision detecting signal transferred from each station and inhibiting repeating processing to the station generating the fault. CONSTITUTION:When a fault such as disconnection is generated in a segment 12a, all data transmission is set to a collision state. A monitoring circuit detects the generation of abnormality in the segment 12a based on a collision detecting signal Aa from the segment 12a and a detecting signal from a carrier sensing circuit. When an abnormality detecting signal is outputted from the monitoring circuit, a repeating control circuit 20 decides the generation of abnormality in the segment 12a, stops the repeating processing to the segment 12a and executes the repeating processing mutually in segments 12b-12n excluding the segment 12a. When abnormality is generated in a segment, the repeating processing to the abnormal segment can be stopped.
