Abstract

PURPOSE: To enable analog input, by providing the comparator which copares the analog signal from the computer with the DA conversion output of the counter output and the operation unit which increases or decreases the counter according to the output of the comparator.
CONSTITUTION: The computer 1 computes the manipulated value from the set value to the controlled variable and the measuring value and the result is output in analog signal. The backup controller 2A compares the output of it with the result at the comparator 26. If this output is positive, the operation unit 27 indicates the count-up to the digital counter 24 and if negative, the countdown is indicated. According to this instruction, the digital counter 24 changes the value, and after the output signal is converted into an analog signal at the DA converter 25, it is delivered to the manipulation section. The count value is change with the pulse generator 23 at manual control.
