Abstract

PURPOSE: To secure an effective inquiry for the cause at the time of maintenance and especially at the time of occurrence of the fault, by displaying the analog signal of the device which is controlled by the CPU onto the CRT for display of the information in the CPU via the program.
CONSTITUTION: The maintenance signals S0WSn are applied to the signal selecting circuit 1; the maintenance signal corresponding to the desired device is selected by the device selection signal; and the sampling signal is delivered for sample holding and then the A/D conversion 2. The digital signal thus obtained is stored in the sense register 3, and at the same time an interruption is applied to the information indicating program of the CRT display unit 5 in the CPU. The contents of the register 3 is sent to the display process program 4 in the timing of the effective signal, and then stored and read out by one picture frame through the display memory provided to the CPU memory and according to the program to be displayed on the unit 5. As a result, an effective inquiry is possible for the cause at the time of maintenance and especially at the time of occurrence of the fault.
