Metodología para la transformación de diseños en GRAFCET a código IEC 61131-3

Abstract

This study presents a methodology for generating control code by applying methodologies that follow standards in accordance with current reference architectures in the industrial automation field. The code is generated in structured text language compliant to IEC 61131-3 from GRAFCET’s design. This is generated following industrial automation (MeiA) methodology. The transformation phases encompass obtaining the necessary information from the designs, structuring the information into a specific format, and post-processing it for the target programmable logic controller (PLC). The results show a considerable reduction in both development time and implementation errors. It is concluded that the legibility of the code obtained in the transformation process allows improving the communication between designing and programming staff. In addition, it simplifies running, modifying, and maintaining the generated code and it facilitates tracing between design and implementation.
