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.

Abstract: A communications network having a master subscriber M and at least one slave subscriber. At least one distribution node CU1, CU2, CU3, CU4 is provided which has a plurality of input/output interfaces, each of which is connected to a network segment, the master subscriber M arranged in a first network segment M1 and the slave subscriber arranged in a second network segment S1, S2, S3, S4, S5. Data is exchanged between the master subscriber M and the slave subscriber in the form of telegrams initiated by the master subscriber. The telegrams to be sent from the slave subscriber to the master subscriber are each assigned control data containing a forwarding time information when the corresponding telegram is to be output from the distribution node via the input/output interface in the direction of the first network segment comprising the master subscriber, the forwarding time information determined by the master subscriber M.

Abstract: A method for transmitting data in an automation network by telegrams, where the automation network comprises a master subscriber, slave subscribers and at least one unlocker, connected to each other via a data-line network. The slave subscribers are divided into segments. The master subscriber sends locked telegrams for processing by the slave subscribers, each having a telegram identifier used to assign a locked telegram to a segment. At least one segment is assigned to at least one unlocker. If the unlocker receives a locked telegram, the unlocker checks, by the telegram identifier in the locked telegram, whether the locked telegram for the assigned segment is intended to release the locked telegram, as an unlocked telegram for processing by the slave subscribers, provided that the locked telegram is intended for the segment assigned to the unlocker.

Abstract: 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.

Abstract: Data transmission in a communication network is performed via a transmission path with which a master participant and at least one slave participant communicate. The master participant outputs messages on the data transmission path with which the slave participants exchange data on the fly. The messages output by the master participant contain datagrams which comprise a control data field and a payload field, where the control data field has a command field and an address field. In the case that at least one message has at least one datagram which is a write datagram in which the command field defines the data transmission procedure to be performed by a slave participant with the payload field as a write procedure, at least the control data field of a further datagram is arranged between the control data field of the write datagram and the payload field of the write datagram.

Abstract: A communications network comprises a plurality of participants. A first participant transmits a message repeating sequence of N?2 successive messages to a second participant. An action which can be performed by the second participant is assigned to each message in the sequence. The first participant begins to transmit one of the N messages at N successive transmission times T_I (I=O, . . . , N?1). Each of the N messages contains a field defining a waiting time. The second participant selects one message from among the messages in the sequence which are successfully received by the second participant as a useful message, measures a time elapsed since reception of the useful message, and performs the action assigned to the useful message when the elapsed time has reached the assigned waiting time.

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.

In this case, the first network participant forwards the data message via the second connection, clearing down the second connection, and re-establishes the second connection, where the parameter for the second connection is set to the first value.
