Abstract: A receiving logic of a network subscriber can be configured in a first filter setting to forward telegrams having first and second addressing techniques to first and second processing units, with a transmitting logic configured to forward the telegrams to a transmitting port. In a second filter setting, the receiving logic can be configured to duplicate the telegrams and forward to the first and second processing units, with the first processing unit configured to discard telegrams using the second addressing technique and the second processing unit configured to discard telegrams using the first addressing technique. The receiving logic of a third filter setting can be configured to duplicate telegrams and forward to the first and second processing units, with the transmitting logic configured to forward only telegrams using the first addressing technique from the first processing unit, and only telegrams using the second addressing technique from the second processing unit.

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 is described for operating a communication network with a plurality of subscribers. Data exchange between the subscribers takes place in the form of telegrams, which comprise data sections. The subscribers interpret an end portion of the telegrams as a check value for the absence of errors in preceding data sections. The telegrams are processed in pass-through, so that the telegrams are forwarded to a respective next subscriber while being received. If an error is detected when receiving a telegram, the subscribers send the telegram to the next subscriber with a characterizing data section at the end, so that the telegram has an end portion representing an invalid check value. The telegram is characterized by the characterizing data section, which is part of the end portion, so that the telegram is not to be considered as an initial error but as a subsequent error.

Abstract: An automation network with network subscribers is provided, in which the network subscribers are interconnected via a data line network. At least one network subscriber is configured as a master subscriber, which is adapted to send telegrams via the data line network. At least one network subscriber is configured as a network distributor, which is adapted to route telegrams. The network distributor has a plurality of input/output ports, and is connected to the master subscriber via a first input/output and data line network. The master subscriber is configured to use a telegram element to indicate that the telegram is enabled for processing by the network subscribers. In addition, the network distributor is configured to process a telegram received via the first input/output port when the telegram element indicates enablement of processing of the telegram by the network subscribers.

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.

Abstract: A method for synchronizing time in an Ethernet-based network having a master network subscriber, a first segment and a second segment. Each segment has at least one network subscriber. The second segment is connected to the first segment by a first network distributor, arranged in the second segment. The method comprises steps for sending out a synchronization telegram addressed to the second segment by the master network subscriber, the synchronization telegram being of the first type; receiving the synchronization telegram by the first network distributor, for conversion into a second type; forwarding the synchronization telegram to a network distributor of the second segment, by the first network distributor; reading out a synchronization value stored in the synchronization telegram by the first network distributor of the second segment; and adjusting a speed of a local system time of the network distributor of the second segment, using the synchronization value.

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. The network distributor outputs them on the further input/output port assigned to the respective routing information, in order to detect network subscribers connected to the respective further input/output ports.
