Abstract: An automation network comprises at least one master subscriber, at least one switch, and at least one subscriber. The master subscriber comprises master ports, the switch comprises switching ports, and the subscriber comprises ports, each comprising a transmitter and a receiver. The master subscriber is configured to output first and second telegrams to first and second switching ports via first and second master ports and first and second master communication paths. The switch is configured to forward the first telegram to a first port of a subscriber via a first communication path, and to forward the second telegram to a second port of a subscriber via a second communication path. In error mode, the switch and the subscriber are configured to return the first telegram to the master subscriber via the first master port, and/or to return the second telegram to the master subscriber via the second master port.

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: In an automation-communication network, at least one distribution node comprises input/output interfaces each connected to at least one network segment. In a first network segment a first subscriber and in a second network segment a second subscriber are arranged. Data are exchanged between the first and the second subscriber by telegrams realized as scheduled telegrams and unscheduled telegrams. The distribution node receives an unscheduled telegram on an input/output interface and sends an unscheduled telegram on a further input/output interface. The distribution node determines a transmission duration for transmission of the unscheduled telegram. The distribution node transmits the unscheduled telegram. Prior to transmission, the distribution node deposits a first telegram information in a data field. The distribution node fragments the unscheduled telegram if the telegram cannot be transmitted within a time slot. Prior to transmission of the unscheduled telegram, the distribution node enters a second telegram information into the data field.

Abstract: A first participant transmits a clocked data sequence to a second participant of a communication network, wherein one data unit of the data sequence is transmitted per clock cycle by the first participant and wherein the data sequence contains a datagram as a write datagram which contains a header, an intermediate field following the header and a data field following the intermediate header, wherein the header, the intermediate field and the data field in each case have one or more data units. The second participant reads the header of the datagram, defines input data depending on the content of the header within a response time, and records the input data in the datagram while the data sequence passes through the second participant. The length of the intermediate field of the datagram is matched to the clock frequency of the data sequence and the response time of the second participant.

Abstract: A data network comprises a master, a network distributor and a plurality of network users. The network distributor is connected to a master data path, a first and a second user data path. A method for transferring data telegrams in this data network includes the reception of a first master data telegram sent by the master through the network distributor, the compilation transfer of a first and a second transmission data telegram through the network distributor, and the reception of a first and a second reception data telegram through the network distributor. Further, the network distributor compiles a second master data telegram and transfers it to the master. In this connection, an access indicator of the second master data telegram represents accesses of the network user to the first master data telegram, the first and second transmission data telegrams as well as the first and second reception data telegrams.

Abstract: In a network, a control node is connected to a plurality of network subscribers via a closed ring-shaped data path, wherein the network subscribers form a chain, starting from the control node, with a head subscriber as a termination for the chain. The ring-shaped data path transits through the network subscribers on an outbound route and an inbound route, wherein the network subscribers are designed to perform data interchange both on the outbound route and on the inbound route with data messages circulating on the ring-shaped data path. The control node is additionally designed such that it outputs data messages with an identifier on the data path, wherein the head subscriber has a filter function to use a prescribed identifier to block the further transport of data messages with the corresponding identifier on the inbound route following transit of data messages through the head subscriber on the outbound route.

Abstract: A method for processing telegrams in an automation network provides a master subscriber to at least partially encrypt and output telegrams, respectively, to another subscriber. The other subscriber comprises an input port, a receiving logic connected to the input port, a decryption unit connected to the receiving logic, and a processing unit connected to the decryption unit and the receiving logic. The receiving logic is configured, when a telegram at least partially encrypted by the master subscriber is present at the input port, to forward an encrypted portion of the telegram to the decryption unit. The decryption unit is configured to decrypt the encrypted portion of the telegram with a key, and to forward the encrypted portion to the processing unit for processing. If an unencrypted telegram is present at the input port, the receiving logic is configured to forward the unencrypted telegram to the processing unit for processing.

Abstract: A network distributor has a plurality of input-output ports, a processor unit, and a memory unit. The ports connect network subscribers via a data line network, where the network subscribers include protocol subscribers to process telegrams as protocol telegrams. The processor unit receives telegrams via one port and outputs telegrams via another port, which is stored in a routing table in the memory unit. The processor unit further determines whether a telegram is a protocol telegram received via a port for which no port identifier is stored in the memory unit, and to discard the telegram if so. Checking and discarding of telegrams can be subject to a precondition, where fulfillment of the precondition leads to an exception from discarding the telegram.
