Abstract

PURPOSE:As for data transmitting sistem connecting one control station with plural terminal station by means of communication line, when control code meaning the right of transferring data communication is sent from main station having the right to adjoing slave station, which may become new main station owing to receiving the code. When data is communicated from main station to slave station, the data may immediately be sent back to the main station by the slave station so that the main station can collate the data and detect error.
