Automatic Control Code Generation from SAMA Specification

Abstract

Industrial process automation engineering implements a control code of a process plant manually. This paper proposes an approach that reads a control specification as a multi-page graphical document and implements control code as a Control logic diagram (CLD) for a target controller. We use a novel vector image processing-based approach to extract entities, equipment blocks, and the control flow from this document. We represent the control flow information as language-agnostic intermediate equipment and control flow graph. The translator traverses the graph and applies a set of mapping rules to generate the control logic. A preliminary analysis reveals that our approach has the potential of saving a significant amount of manual effort to generate a CLD from such a specification.
