摘要
A distribution node for an automation network comprises at least two input/output interfaces for transmitting and receiving real-time-relevant and non-real-time-relevant data packets, and a switching device connected to the input/output interfaces. The switching device forwards data packets received via an input/output interface via a further input/output interface using a switching table, where the switching table contains at least a data packet identifier and a transmission time in a data transfer cycle for each real-time-relevant data packet. Inter alia, the switching device can detect a data packet identifier on reception of a real-time-relevant data packet, and output the real-time-relevant data packet at the transmission time allocated to the detected data packet identifier in the switching table via an input/output interface as a transmission interface.
