Document Type and Number:
Japanese Patent JPS6019205
Kind Code:
A
Abstract:
PURPOSE:To detect quickly a defect of a soft signal which is difficult to be visually recognized by storing once the working contents of an electronic computer into a memory and then displaying the contents of the memory to a display device when a fault is detected. CONSTITUTION:When a microcomputer 2 provided on a tacker crane 1 used in an automated warehouse detects a fault, this fault is displayed at an LED6 on a setting board 5 provided on the ground. In this case, the presence or absence of a fault is decided from an input processing result obtained from a program set to the computer 2. If no defect is decided, a command is given to a working program of the crane 1. Then the working contents are stored in a memory. This memory contents is displayed in two digits by the LED on a setting board 5 for each push of a push-button 6. Thus the contents of the soft processing are decided together with the input signal. As a result, an operator can decide quickly a faulty area.
