PURPOSE:To enable just a single operator to perform the wiring check with high efficiency by providing a wiring check mode and giving the simulated operations to input devices in the fixed order. CONSTITUTION:A changeover switch 91 is set at the wiring check position. When a lamp 92 glows to show the end of preparatory for wiring check, an operator gives successively the simulated operations to the input devices connected to an input interface 4. Thus a history memory 8 stores the simulated action numbers and their corresponding input numbers. When the simulated actions of all input devices are through, the contents stored in the memory 8 are read out successively and displayed on a display device 94 in response to the signal arrival numbers. Thus the operator can confirm the correct or incorrect wiring of each input/output device from those simulated action numbers and input numbers displayed on the device 94. In such a way, just a single operator can perform the wiring check with high efficiency. |
