Towards a Property Preserving Transformation from IEC 61131-3 to BIP

We report on a transformation from Sequential Function Charts of the IEC 61131–3 standard to bip. Our presentation features a description of formal syntax and semantics representation of the involved languages and transformation rules. Furthermore, we present a formalism for describing invariants of IEC 61131–3 systems and establish a notion of invariant preservation between the two languages. For a subset of our transformation rules we sketch a proof showing invariant preservation during the transformation of IEC 61131–3 to bip and vice versa.
