Abstract

PURPOSE:To cut off the station itself from the loop by the end signal, by transmitting the data and the end signal addressed to slave stations and also the start signal from the master station connected with the slave stations in loop, and by excuting the data processing addressed to the slave station and data reproduction and relay addressed to other stations. CONSTITUTION:Data transmission is made by connecting a plurality of slave stations 2 to the master station 1 in loop. The slave stations 2 are provided with the microprocessor 4 connected to the common bus line 10, memory circuit 5, interface circuit 6 with external units, reception circuit 7, transmission circuit 8 and control circuit 9. The control circuit 9 is provided with the switch control circuit 11 controlling the switch 12 connected to the transmission line 3, a plurality of start signals, data signal addressed to the slave stations and data end signal are transmitted from the master station 1, the data addressed to a slave station with the circuit 7 of the slave station 2 is received for processing and the data addressed to other stations are reproduced and relayed and transmitted from the circuit 8. Further, the end signal cuts off the slave station from the loop with the switch 12, allowing each slave station 2 to receive the start signal within a given time.
