Abstract

PURPOSE: To change many function programs freely by making each function into a block, by providing input-output terminals to hardware constituting each block unit, by changing connections between terminals by a control program.
CONSTITUTION: Respective function programs on a microprogram package substrate are provided with input-output terminals DI-1WDI-n, and DO-1WDO-n, connections between which can freely be changed by an user through control program 100. This control system is composed of A/D converters A and B providing the A/D conversion of a reference input and feedback input from a unit to be controlled, blocks C and D multiplying the conversion output by constants K1 and K2, and block E calculating the difference between the outputs of blocks C and D; and block F exercises proportional-plus-integral-plus derivative-control (PID control) on the basis of the calculated difference and block G makes a check on the highest and lowest limits of the control results. Then the results of the check are applied to the controlled unit through D/A converter H for the control.
