Abstract

PURPOSE: To simplify the fitting work to the mechanical device and the maintenance work, by constituting the unit, which controls the interface between the bus line and each I/O element, by a signal converting part, an address identifying part, a power amplifying part, a clear signal generating part, and so on.
CONSTITUTION: Interface unit iFU to be connected to bus is constituted as follows; the input signal from input element 114 is applied to signal converting circuit 101, which processes the signal on line BL, through signal converting part 101A and NAND gate 112, and the output of circuit 101 is branched and is applied to inverter 108, counter 102, and clear signal generating part 105, and the output of inverter 108 is transmitted to output element 113 through latch circuit 109 and power amplifier 110, and at this time, the output of counter 102 controlled by generating part 105 is compared with the output of I/O address setting equipment 104 by comparator 103, and the comparison value is latched in circuit 109 through delay circuit 106.
