As a standardized communication protocol, OPC UA is the main focal point with regard to information exchange in the ongoing initiative Industrie 4.0. But there are also considerations to use it within the Internet of Things. The fact that currently no open reference implementation can be used in research for free represents a major problem in this context.(More)
Representational state transfer (REST) is a wide-spread architecture style for decentralized applications. REST proposes the use of a fixed set of service interfaces to transfer heterogeneous resource representations instead of defining custom interfaces for individual applications. This paper explores the advantages of RESTful architectures, i.e.,(More)
A game-theoretic model for the study of dynamic networks is proposed and analyzed. The model is motivated by communication networks that are subject to failure of nodes and where the restoration needs resources. The corresponding two-player game is played between " Destructor " (who can delete nodes) and " Constructor " (who can restore or even create nodes(More)
Describing procedures is essential for modeling and controlling technical processes. Although various procedure description methods are available from computer science, system theory and industrial automation, they are only partially suitable as a generic method for engineering automation procedures. In order to close this gap, we propose a procedure(More)
Integrating control development phases requires a consolidated communication architecture. Currently, different communication protocols are used at the different development stages preventing a fully integrated solution to exist. We propose an approach using a unified communication protocol to jointly integrate the control development stages. MATLAB and(More)
