Abstract: A method for routing telegrams in an automation network with network subscribers interconnected via a data line network. At least network subscriber is a master subscriber, which sends telegrams to the network subscribers via the data line network. At least one network subscriber is a network distributor having a plurality of input/output ports, where input/output ports to which segments with further network subscribers are connected are designated as end ports. The master subscriber assigns a port address to each end port, and assigns the port address as an identifier to a telegram intended for processing for a segment with further network subscribers. If the network distributor receives a telegram with a port address of an end port of the network distributor as an identifier, the network distributor outputs the telegram directly via the input/output port of the network distributor corresponding to the end port of the port address.

Abstract: A method for detecting network subscribers in an automation network by query telegrams provides that a protocol-network subscriber enters network-subscriber information into a query telegram and sends the query telegram to a subsequent network subscriber. If no subsequent network subscriber is connected to a data line, other than the receiving data line, it sends the query telegram back to the configuration subscriber. A network distributor enters port information on the further input/output ports of the network distributor, to which further data lines are connected into the query telegram, and returns it to the configuration subscriber. The configuration subscriber subsequently generates further query telegrams, each with routing information on the basis of the port information, and sends them to the network distributor.
