IEC 61131-3 model for model-driven development

Existing industrial automation projects require automated methods for faster changes and updates as well as continuous improvement and maintenance. Software Engineering uses Model Driven Development to shorten the development time by keeping documentation, models and code consistent during the whole development time and by using code generators to create many similar code artifacts and code for different platforms. To make this concept also available for automation projects we present an IEC 61131 model based on the Extended Backus Naur From provided by the standard. For the proposed IEC 61131 model also related application areas are outlined.
