Automatic Generation of AWL Code from IEC 61499 Applications

The paper deals with the implementation of IEC 61499 applications into executable code. In particular, this work concerns the automatic conversion of a IEC 61499 application into an AWL application executable on a standard Siemens PLC. The IEC 61499 Standard defines an application as a network made of Function Blocks and event/data connections. The behaviour of a single Function Block and of an application is also specified in the standard. At the moment, there are no industrial solutions supporting this standard: from that the need to cover the gap between the standard and the existing legacy devices.
