A CONCEPT FOR THE SYSTEM INTEGRATION OF WIRELESS SENSOR NETWORKS TO INDUSTRIAL AUTOMATION SYSTEMS USING PROFINET

Contemporary industrial automation systems are using real-time Ethernet protocols, like PROFINET, for exchanging process and configuration data. In order to make automation systems more flexible and due to many other advantages, wireless technologies are introduced in certain application areas, e.g. the connection of sensors by the use of a wireless sensor network. In this typical scenario the integration of a newly deployed wireless sensor network into an existing system is required and of vital importance. This paper gives a short introduction to different wireless technologies that are being discussed at the moment for wireless sensor networks (WSNs) and to PROFINET IO. It also proposes a feasible integration approach regarding application layer object models and their corresponding mapping.
