A User-Friendly Verification Approach for IEC 61131-3 PLC Programs

Abstract: Programmable logic controllers (PLCs) are special embedded computers that are widely used in industrial control systems. To ensure the safety of industrial control systems, it is necessary to verify the correctness of PLCs. Formal verification is considered to be an effective method to verify whether a PLC program conforms to its specifications, but the expertise requirements and the complexity make it hard to be mastered and widely applied. In this paper, we present a specification-mining-based verification a… Show more
