Abstract: In this paper we examine architectures for non-real time (NRT) traffic handling in PROFINET nodes. Much work has gone into optimising communication controllers for real time traffic resulting in several implementations capable of handling cycle times down to and lower than 250us, in some cases down to 31.25us. Industry experience shows that if the system experiences problems large quantities of data must be shifted between nodes whilst isochronous fidelity is upheld. In particular architectures this can be problematic and we examine architectures typical of those on today’s market, suggest improvements and back these up with measurement data.
