Catalog of Refactoring Operations for IEC 61499

Refactoring is a key technology for improving the quality of a software system. A higher quality will lead to a clearer structure, which facilitates sharing work across multiple teams. This is important especially in the domain of cyberphysical production systems, where different engineering disciplines meet at their cutting point. IEC 61499 tries to abstract the increasing complexity of such systems. This work gives an overview of existing refactoring techniques from software engineering and provides a first insight on how to apply refactoring to IEC 61499 systems.
