PURPOSE:To miniaturize the constitution of hardware by changing over input/ output signals on the hardware and an output signal on software at 1:1 or 1:multiple and specifying correspondence relationship. CONSTITUTION:An input/output mechanism 12 makes the signals of input/output circuits 5-11 on hardware and input/output signals 'A'-'D', 'L'-'N', 'e'-'g', 'h'-'m' on software correspond. Where 'k' and 'i' are made to correspond when a changeover signal (x) is not input, and 'm' and 'i' are made to correspond when the changeover signal (x) is input. Accordingly, the input/output signals on software and the input/output signals on hardware are made to correspond properly, thus miniaturizing the constitution of the hard ware. |
