Abstract

PURPOSE:To monitor clearly the progress rate of control, by enabling a display device which displays arithmetic results of steps by binary numbers, to make the specific display which indicates that an instruction is not executed before the execution is completed. CONSTITUTION:The program for sequence control is stored in memory 3 and when this is executed by CPU2, the set value of numeral setter NK in console 7 is read to display the number of a step at the high-order two digits of display device 6. Then, the last read contents and current read contents are compared mutually to decide whether the set value has been changed or not and when it has been changed, display device 6 displays ''-'' at the 3rd digit to show that the instruction is not executed. This is to be executed under the 1st control after the power source is put to work. On decoding instruction words, the read contents of setter NK and those of a program counter are compared mutually and when the completion of the execution of the instruction word in the step designated by memory 3 is detected, ''H'' or ''L'' is displayed at the 3rd digit of display device 6 as the arithmetic result of the step, the instruction in the next step is executed successively.
