PURPOSE:To improve the reliability and efficiency of transmission by permitting a sub-station to return a confirmation response with respect to a receiving signal and reporting the interruption request of the sub-station. CONSTITUTION:A central station is provided with a computer controlling the central station and a microprocessor muPC communicating through plural interface registers. The muPC also communicates between microprocessors muPSi of respective sub-stations. The muPSi of each sub-station controls its sub-station. Conductors TXD and RXD transfer information transmitted from the central station to the sub-station and that transmitted to the central station from an arbitrary sub-station, respectively. Registers include a STATUS register, a COMMAND register, an ADDRESS register, a WR.DATA register and an RD.DATA register.
