Modularization Of Control Software: Efficient Engineering With Iec 61131 And Iec 61499

Modularization and distribution of the responsibilities of an automation system are important for increasing the reusability of automation hardware and software. For this purpose, a new hierarchization approach for automation systems that decouples the sequence control from the hardware control and a seamless integration of cycle-based IEC 61131 systems into the development models of the event-driven IEC 61499 are presented. Both approaches pay special attention to the reusability of software.
