Abstract
For the replacement of old sequential controllers for plants to modern programmable controllers(PCs), we have developed the sequential control programs automatic inductive regeneration method (SPAIR) system from input-output signals and action specifications of a target controller. However, this method cannot regenerate the logic included in the interior coils. Therefore, we propose an efficient inference method of interior coils logic for SPAIR using Logic Part Attaching Algorithm. In this method, the target logic of the interior coil is acquired by the selective attachment of logic parts. We confirmed the effectiveness through the application of this method to some original controllers including interior logics.
