Generation of control for conveying systems based on component approach

This paper proposes a methodology for automatic control generation of conveying systems. Its purpose is to automate the development of discrete control programs in order to reduce costs. It is based on components to model controlled conveying systems. A component is a reusable element that includes several views including partial models. It is formalized referring to the notion of operations. Four views are delineated in this paper: operating part view, constraints view, topological view and control view. The control model of the workshop is built on these views. The procedure uses these partial models and refers to model transformation to provide an easy way to obtain source code compatible with the IEC 61131-3 standard. Tools allowing to implement the methodology are also presented, along with some applications.
