    4DIAC – Ein Open Source Framework für verteilte industrielle Automatisierungs- und Steuerungssysteme
    (INFORMATIK 2010. Service Science – Neue Perspektiven für die Informatik. Band 1, 2010) Strasser, Thomas; Zoitl, Alois; Ebenhofer, Gerhard
    Dieser Beitrag gibt einen Überblick über das IEC 61499 Referenzmodell für verteilte Steuerungssysteme sowie über den aktuellen Stand der Open Source Initiative „4DIAC - Framework for Distributed Industrial Automation and Control“, welche es sich zum Ziel gesetzt hat, eine quellenoffene IEC 61499 Referenzimplementierung zur Verfügung zu stellen, die den Anforderungen Portabilität, Konfigurierbarkeit und Interoperabilität genügt. Die 4DIAC Open Source Initiative ist sowohl für akademische Forschung als auch für die Verwendung in industriellen Prototypen und Produkten gedacht, wobei durch die Kooperation von Forschung und Industrie eine gute Basis für die Anwendung von IEC 61499 Applikationen geschaffen werden soll. Der Beitrag befasst sich weiters noch mit ausgewählten Steuerungsbeispielen auf Basis von 4DIAC und schließt mit einem Ausblick über zukünftige Entwicklungen der 4DIAC Open Source Initiative.

    Assessing the Usefulness of a Visual Programming IDE for Large-Scale Automation Software
    (Software Engineering 2022, 2022) Wiesmayr, Bianca; Zoitl, Alois; Rabiser, Rick
    This is a summary of a paper (with the same title) that we published at the ACM/IEEE 24th International Conference on Model-Driven Engineering Languages and Systems (MODELS 2021) describing a study centered on a visual programming IDE for large-scale automation software development and maintenance.

    Modularization Guidelines to Support Control Software Variability in IEC 61499
    (SE 2024 - Companion, 2024) Sharma, Shubham; Hager, Anna-Lena; Zoitl, Alois
    In the field of Cyber-Physical Production System (CPPS), a substantial number of control software components are integrated with legacy software. This legacy control software has existed in industries for decades and faces maintenance problems due to sub-optimal tool support. Consequently, rigid software structures have emerged, making maintenance difficult and necessitating better support for managing variability. These legacy systems contain an enormous volume of control software, making it impractical to transform manually in terms of variability management. Additionally, there is a growing demand for variability to accommodate to customer-specific requirements. Control software must be flexible and modular enough to fulfill diverse project-specific needs. Guidelines are required to assist control system engineers in determining which control software components must be refactored and which can be left unchanged. We investigated legacy control software from industrial use cases, identified problem areas, and gathered lessons learned. These lessons have been translated into guidelines for future control software modularization. Hence, in this paper, we present a set of guidelines aimed at modularizing IEC 61499 control software, specifically focusing on enhancing control software variability for variability-intensive CPPS.

    Workshop on Software Engineering in Cyber-Physical Production Systems (SECPPS), 2nd Edition
    (Software Engineering 2022, 2022) Rabiser, Rick; Vogel-Heuser, Birgit; Wimmer, Manuel; Wortmann, Andreas; Zoitl, Alois
    This workshop focuses on Software Engineering in Cyber-Physical Production Systems (SECPPS). SECPPS is an interactive workshop opened by keynotes and lightning talks, followed by project showcase presentations, and concluded by extensive discussions in break-out groups. The main output of SECPPS 2022 is an updated research roadmap as well as concrete networking activities to further grow the community in this interdisciplinary field.
