Abstract

PURPOSE:To improve the reliability and increase the number of installed local stations, by providing plural transmitting and receiving circuits in a master station and plural common busses and transmitting address information of local stations onto plural common busses simultaneously. CONSTITUTION:In the system constituted with one master station 1 and local stations 5B1-5Bn, 5C1-5Cn, and 5D1-5Dn connected to plural common busses 31-33, plural transmitting and receiving circuits 9A-9C are provided in the master station 1, and common busses 31-33 are connected to transmitting and receiving circuits 9A-9C respectively. Consequently, when local stations are installed distributively, the transmission length per one common bus is shortened, and the number of local stations 5B1-5Bn, 5C1-5Cn, and 5D1-5Dn connected to one master station 1 is increased.
