Abstract

PURPOSE: To investigate the cause of trouble easily on reading the content as required by storing a status of the input-output device for every variation of the input- output status and by storing from the initial address again when a specified memory capacity is exceeded.
CONSTITUTION: A position control loop is formed with the processor 1, common bus 2, memory 3, I/O device 5, main amplifier 6, motor 7 and position detector 8. The I/O device 4 is for delivering the machine tool operation and auxiliary function signals, the tape reader 9 is for reading a command data. The data processing memory stores a status of I/O device in the status memory area for every variation of the I/O device, and repeats from the initial address again at the time the status memory area is filled. When a trouble occurs, the status of I/O device written in the memory area is read to investigate the cause of trouble occurrence.
