SYSTEM AND METHOD FOR THE PARALLEL TRANSMISSION OF REAL-TIME CRITICAL AND NON REAL-TIME CRITICAL DATA VIA SWITCHED DATA NETWORKS, ESPECIALLY ETHERNET

摘要

The invention relates to a system and to a method that allows both real-time critical and non real-time critical communication in a switched data network, comprising subscribers and coupling units, for example a distributed automation system by cyclic operation. In a so-called transmission cycle (12), at least one area (13) is available to all subscribers and coupling units of the switched data network for the transmission of real-time critical data and at least one area (14) for the transmission of non real-time critical data, thereby separating real-time critical communication from non real-time critical communication.
