PURPOSE:To change a slave equipment constituting (1:n) communication as necessary by accommodating a master equipment and the slave equipment in an exchange separately respectively in applying simultaneous communication of (1:n) and using an adaptor when the simultaneous communication of (1:n) is required. CONSTITUTION:The information sent from the master equipment 40 is inputted to the master equipment interface circuit 36 of the adaptor 30 via an exchange 20, stored to a master equipment information buffer register 37 once after being subjected to a required processing and fed to all slave equipment interface circuits 311-31n. Further, the information sent from the side of the slave equipment 10 is inputted respectively to the slave equipment interface circuits 311-31n of the adaptor 30 and stored tentatively in buffer registers 321-32n after being subjected to the required processing. After the required processing is executed, the result is sent to the master equipment 10 via the exchange 20.
