Abstract
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.
