Access to data from components in production systems is potentially an enabler for various data-based approaches. This paper presents a practical approach to transform mechanical components into self-describing cyber-physical systems connected within a local network. The requirements for typical use cases are analysed and a modular cyber-physical connector is proposed. The data is collected by a central OPC UA client and fed into a web-based visualisation, so that it is easily accessible for operators, maintenance staff, and other stakeholders. The approach is illustrated for components with two different levels of complexity.

Shorter product lifecycles lead not only to faster time-to-market for products but also to the need for just as fast available associated production systems. These shorter product lifecycles, as well as the increasing individualization of products, also result in further decreasing production lot sizes. Young companies in China in particular are characterized by a very high speed of innovation but may not have the necessary manufacturing knowledge or capacities to bring their developed products to the market with a scalable production. For this reason, there is a great need to quickly set up and commission turnkey production systems or to reconfigure existing production systems for new production tasks in the shortest possible time. This paper describes the design and architecture of a cloud platform with the aim to support a manufacturer independent design process for turnkey production systems. This process ranges from the product to be manufactured to the operation of the production system. Firstly, the structure and methodology used to link the various objectives are discussed. The system for recording and structuring product and production system data to create reusable modules from components and machines is described. Subsequently, the use of standardized modules is developed to support reconfiguration of the production system during operation. In addition, the digital business models tailored to the production system are proposed to the platform user for commissioning and operation of the plant. A case study is conducted to validate the proposed methodology.

In machine tools, Industry 4.0 functions can increase availability through predictive maintenance, while other functions improve productivity and workpiece quality through process supervision and optimisation. Many of these functions rely on data communication between systems from different suppliers. Requirements regarding latency and computing vary widely depending on the application. Based on an analysis of these requirements, a smart controller for the implementation of Industry 4.0 is designed, using a hypervisor to allow for the integration of soft real-time and best-effort applications.

The digitalisation of production technology is becoming increasingly important today and will play a key role in machine tools in the future. In order to generate as much information as possible about machines and components as well as the product, the number of sensor systems and further devices is con-stantly increasing. A challenge with this increasing number of data sources is the also increasing complexity of the system with regard to the generation of the ma-chine tool’s digital twin that is to be fed from these data sources. For this, a ho-listic approach is necessary which combines all parameters and values with a uniform semantics and links them to the corresponding data sources. For this purpose, this paper uses a uniform information model to describe a machine tool, which is linked to the respective node variable names in the respective OPC namespace of the machine tool. In the event that this linkage plan is incomplete or completely missing, this paper presents a concept for a so-called crawler tool, an OPC client application. The crawler searches the parameters and values in the described OPC namespace of the machine tool, identifies them by domain knowledge-driven plausibility checks and assigns them to the corresponding pa-rameters of the information model of the machine tool.

Shorter product lifecycles and increasing individualization of products lead to the necessity for a reoccurring process, which includes the selection and configuration of production systems to provide a system that produces the product. Especially in fast developing countries like China, the offer for this knowledge can hardly supply the demand. In order to solve this, this paper presents a systematic approach in the form of a multi-stage process. In the first stage, a configuration logic maps product requirements with the properties and specifications of production machines together with equipment and matches them using a uniform data information model for both products and production modules. In the second stage, the turnkey production system is set up, commissioned and operated based on the Industrie 4.0 administration shell. The presented approach has been prototypically implemented on an online platform and demonstrated on a real production system using a new product that has been integrated into production.

Bereits heute existieren vereinzelt vielversprechende industrielle Anwendungen der Künstlichen Intelligenz, vor allem in den Bereichen Prozess- und Zustandsüberwachung. Heutige KI-Modelle werden jedoch ausschließlich als Insellösungen für einen Prozess und eine Maschine entwickelt. Durch heterogene Produktionsanlagen existieren kaum prozess- und zustandsübergreifend anwendbare KI-Modelle. Wie gelingt daher eine breite Übertrag- und Skalierbarkeit der Anwendungen in der gesamten Produktion? Dies erfolgt einerseits durch die Vereinheitlichung der Informationsmodelle verschiedener Maschinen durch intelligente Parameteridentifikation (Crawling) sowie in einem zweiten Schritt durch eine Datensegmentierung zum Aufbau strukturierter Datenbasen (Clustering). Auf Grundlage von kontextbasieren Datenbasen, die aus einem einheitlichen Informationsmodell aus unterschiedlichsten Maschinen entstehen, können KI-Ansätze skaliert und auf die gesamte Produktion übertragen werden.
