Abstract
In an automation communication network, a distribution node is provided with a plurality of input/output interfaces, each connected to a network segment having at least one subscriber. The network segments are each assigned segment telegrams for processing by the subscriber. The segment telegrams have a data field with sequence information indicating the priority of a subsequent segment telegram. The distribution node is configured to receive the segment telegram on an input/output interface and transmit it according to a routing specification on a further input/output interface. The distribution node blocks the input/output interface on which the segment telegram has been transmitted for further transmission if the telegram sequence information indicates a priority for the subsequent segment telegram with the same routing specification, which is higher than the priority of other telegrams intended for transmission on the input/output interface, in order to send the subsequent segment telegram on the blocked input/output interface.
