Transformation of PLC applications for a target platform

Abstract

Embodiments of the invention relate to a computer-implemented method and a computer-readable storage medium for transforming source code for a programmable logic controller (PLC) into the architecture of a target platform. The method begins by reading in automation system data, which includes logic in the form of IEC 61131-3-based source code for a PLC. The source code is parsed and converted into a platform-independent intermediate language. The platform-independent intermediate language is compiled into an object file containing an output format dependent on the target platform. A cyclic execution model is then generated based on the read-in automation system data, such as cycle time and / or a bus configuration of the PLC. The compiled object file is linked with the generated cyclic execution model to create an executable target file.The generated executable target file contains logic equivalent to the logic of the source code programmed in IEC 61131-3 and is executable by the target platform.
