    Das neue Geschäftsmodell, das mit der Industrie 4.0 verbunden ist, verändert ein etab-liertes Dogma der Automatisierungsbranche: Anlagen wurden auf hohen Durchsatz der immer gleichen Produktformate optimiert. Während derartige Systeme mit bekannten Maßnahmen auto-matisierbar sind, stellt die Variantenfertigung eher ein Automatisierungshindernis dar. Für eine individualisierte Produktion ist die Rekonfigurierbarkeit von Industrieanlagen ein wichtiger Fak-tor. Die Modularisierung und automatische Konfiguration sind hierbei wesentliche Triebkräfte. Im Rahmen dieser Arbeit wird eine Basisarchitektur für eine intelligente Netzwerkkomponente vorge-stellt, die ohne manuelle Konfiguration in unterschiedlichen Echtzeit-Ethernet-Netzwerken einge-setzt werden kann.

    Many aspects have to be considered while achieving flexibility of production systems. One of them is flexible communication system that on one hand fulfils requirements of a particular industrial application and on the other hand allows integration of new network components optimally in a seamless way. In this paper, an approach to increase, rather static, Time Triggered Ethernet based systems is proposed. It is based on a greedy scheduling approach that can be implemented directly in a processing limited hardware such as IO Controller. This, together with the discovery and auto configuration mechanism proposed in [1] allows to shift the engineering process typically performed offline using engineering tool to the field level. Furthermore, it has been proven that the proposed scheduling approach is not only simple but also powerful. It is able to calculate an optimal schedule for any kind of tree graph and the complexity of the algorithm is defined by the complexity of the used sorting algorithm.

    Future market conditions require production systems which can be easily adapted to changing demands. However, the engineering process of industrial automation systems is characterized by high manual configuration efforts. Thus, the reconfiguration of such system leads to time-intensive and expensive downtimes. Therefore, this paper will present a concept on reducing the engineering effort - at least on the lower layers of the automation pyramid. Due to the real-time requirements on these layers, specific communication technologies must be used there - for example Real-Time Ethernets (RTEs) which are increasingly applied in industrial automation. However, their real-time capability is contrasted by an additional configuration effort in comparison to standard networks from the information technology domain. This paper will show an approach for the automatic configuration of RTEs and will check its applicability on the most widely-used RTE variants.

    Eine der Herausforderungen an die Fabrik der Zukunft heißt Wandlungsfähigkeit - und zwar nicht nur auf physikalischer Ebene, sondern auch bezogen auf Software. Dabei ist die zentrale Idee, dass sich selbst beschreibende Geräte und Maschinen mit auf akzeptierten Industriestandards basierenden Schnittstellen genutzt werden, wenn neue Komponenten, Maschinen oder Anlagen in ein Produktionssystem eingebracht werden oder sich softwarerelevante Änderungen in der Produktion ergeben. In diesem Artikel beschreiben die Autoren Ansätze zur automatischen Integration neuer oder geänderter Geräte und Maschinen in ein Produktionssystem.

    In the industrial automation a paradigm shift from centralized, static automation structures to reconfigurable manufacturing systems (RMS) might be lie ahead. RMS are seen as a key enabler for the required changeability of future production companies since they can reduce the engineering effort needed for the reconfiguration of existing or the construction of new production systems. However, it is not clear how the companies can benefit from RMS in detail. For example, the reduction of engineering effort cannot be expressed in figures by today. But such information is necessary to convince the industry of the advantages of the new production principle. Indeed, existing RMS paradigms like Service-Oriented Architectures are rarely used in the practice of automation. The basis for analyzing the advantages of RMS is an analysis of the status quo in the industrial automation. Regarding the engineering effort of current automation systems, this paper will present a case study considering the effort occurring during the commissioning process of a production system constructed by state-of-the-art components. The evaluation of the study can serve as a reference when comparing the engineering effort of RMS with today's systems.
