  abstract     = {{The current developments towards the visions of Industrie 4.0 will create open and dynamic architectures being supervised by Industrial Automation and Control Systems. Due to this new connectivity and flexibility, future industrial production systems need to be inspected during all phases of the whole lifecycle from a security point of view as well. Frequent reconfiguration and adaptation based on smart services impose advanced requirements on the audits and certification with regard to security. To facilitate that, this work presents an approach for the modeling of security requirements and capabilities within the Industrial Reference Architecture and evaluates it based on the concrete system architectures of a number of industrial use cases. The result is the Sec4ICS tooling-based concept for the automated assessment of security-related functionalities within industrial systems.}},

  abstract     = {{Cyber-physical production systems (CPPS) integrate physical and computational resources due to increasingly available sensors and processing power. This enables the usage of data, to create additional benefit, such as condition monitoring or optimization. These capabilities can lead to cognition, such that the system is able to adapt independently to changing circumstances by learning from additional sensors information. Developing a reference architecture for the design of CPPS and standardization of machines and software interfaces is crucial to enable compatibility of data usage between different machine models and vendors. This paper analysis existing reference architecture regarding their cognitive abilities, based on requirements that are derived from three different use cases. The results from the evaluation of the reference architectures, which include two instances that stem from the field of cognitive science, reveal a gap in the applicability of the architectures regarding the generalizability and the level of abstraction. While reference architectures from the field of automation are suitable to address use case specific requirements, and do not address the general requirements, especially w.r.t. adaptability, the examples from the field of cognitive science are well usable to reach a high level of adaption and cognition. It is desirable to merge advantages of both classes of architectures to address challenges in the field of CPPS in Industrie 4.0.}},

  abstract     = {{The configuration of current automated production systems is complex and therefore time consuming while the market demands an easy setup and adaptability due to smaller batch sizes and volatile markets. While there are different concepts in research on how to simplify the engineering process by using generic skills or capabilities of devices, run-time control is still achieved with proprietary communication protocols and commands. The concept in this paper uses skills not only in the phase of engineering but also consequently for direct and generic control of field-devices. An executable skill-metamodel therefore describes the methodological functionality which is implemented by using OPC UA due to its vendor independence as well as built-in services and information model. The implementation uses client/server-based OPC UA and the pub/sub pattern to prepare for a deterministic real-time control in conjunction with TSN, which is required by industrial automation.}},
