PURPOSE:To transfer a data by a simple circuit configuration, by connecting a bus of a processing system and a bus of an input/output system by a bus converting and scanning circuit, and converting a data from the bus of the processing system to an address of an equipment apparatus of the input/output system. CONSTITUTION:A master station 22 is constituted of a processing part 23 in which a program for operating a system has been incorporated, and a digital inputting circuit and a digital outputting circuit 26, which have been connected to said processing part by a bus 24. A slave station 27 is constituted of a digital inputting circuit 29 and a digital outputting circuit 30, which have been connected with a bus 28, and the buses 24, 28 are connected to a bus converting and scanning circuit 31. A command information is inputted to a terminal 25a, is processed by the processing part 23, and a data sent out to the bus 24 is converted to an address of an equipment apparatus of the slave station by the circuit 31, is sent out to an address area of the bus 28, and an equipment control information is sent out from a terminal 30a through the circuit 30. Also, an equipment information from a terminal 29a is read by the circuit 29, is scanned by the circuit 31, and a display information, an alarm, etc. are sent out to a terminal 26a through the circuit 26. |
