Response Times Evaluation of PROFINET Networks
Paolo Ferrari, Alessandra Flammini, Stefano Vitturi · 2005
In this paper we address PROFINET, an industrial communication standard based on Ethernet, designed to be employed at different levels of factory automation systems. After a general description, we focus on the two application layer protocols specified by the standard, namely PROFINET CBA and PROFINET IO. In detail, we first illustrate the major protocols features and then present the results of a set of tests we carried out. Regarding PROFINET CBA, the tests have been executed on an experimental set-up, whereas for PROFINET IO we show the outcomes of some numerical simulations. In both cases, the results are in accord with the performance figures envisaged by the PROFINET technical documentation.
