Abstract

PURPOSE: To improve the reliability of diagnosis results by providing an input/ output control part with a diagnostic function to diagnose not only the function of the input/output control part but also the function of a main control part.
CONSTITUTION: In case of diagnosis at the time of power-on, a function diagnosing part 103c checks the sum value of a main control part ROM and checks whether initialization of each circuit is normally terminated or not; and if normalcy is discriminated as the result of check, a main control part 101 is started and the control is transferred to a CRT/KB control part 103a. If abnormality is discriminated, the main control part 101 is not started. In case of normal diagnosis, various processings are requested to an input/output control part 103 through an interrupt control part 104, and then, data is read out from a main storage part 102 and DMA is requested to the main control part 101. If a DMA permission signal cannot be obtained within a certain time, alarm is sent. If diagnosis is requested at the time of abnormality, the function diagnosing part 103c acquires the use right of a bus to control a numerical controller. Hereafter, data is inputted and outputted by the CRT/KB control part 103a and data of the main storage part 102 is displayed on a CRT 105 to diagnose the function.
