PURPOSE:To perform the standardization of hardware and software by performing signal transmission control and input/output signal processing control with a program corresponding to a read ID code out of the programs in a standardized ROM by the microcomputer of each station. CONSTITUTION:The microcomputers of a control station 2 and subordinate stations 4a-4c and 5, after an initial set processing being applied, perform the identification of the specification of its own station by reading a set station number ID code with the unified input port 214 of the microcomputer 200b first. And the signal transmission control and the input/output signal control of respective station can be performed by starting up only a program part corresponding to the ID code in standardized ROM programs. The setting of the station number ID code on the input port part 214 is performed by setting each bit data based on the on/off control of a switch 205a for selection, and a terminating resistor 204 is inserted to a bus line with the switch 205a at a transmission line terminating station. Thereby, the standardization of the software and the hardware can be realized. |
