Controller control logic function comparison method and device, equipment and storage medium

The invention discloses a comparison method and device for control logic functions of a controller, equipment and a storage medium. The method comprises the following steps: acquiring an output function block of each controller in a plurality of controllers and identification information corresponding to the output function block; generating a characteristic value of the output function block based on the identification information corresponding to the output function block; obtaining a superior function block of the output function block, and generating a feature value of the superior function block based on the feature value of the output function block; wherein the upper-level function block of the output function block is a function block located at the upstream of the output function block; and based on the characteristic value of the functional block in each controller, comparing the control logics of the plurality of controllers to obtain a control logic comparison result of the plurality of controller
