Publication number: 20220103337Abstract: 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.Type: ApplicationFiled: December 13, 2021Publication date: March 31, 2022Inventors: Holger Büttner, Dirk Janssen, Erik Vonnahme, Hans Beckhoff, Thomas Rettig, Thorsten Bunte, Johannes Beckhoff, Guido Beckmann, Karl Weber

Publication number: 20220103485Abstract: 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.Type: ApplicationFiled: December 9, 2021Publication date: March 31, 2022Inventors: Holger Büttner, Dirk Janssen, Erik Vonnahme, Hans Beckhoff, Thomas Rettig, Thorsten Bunte, Johannes Beckhoff, Guido Beckmann

Publication number: 20220038306Abstract: A network distributor comprises a plurality of input/output ports, a processor unit, and a memory unit. The input/output ports are configured to connect network subscribers via a data line network, where the network subscribers comprise protocol subscribers configured to process telegrams configured as protocol telegrams. The processor unit is configured to receive telegrams via one input/output port and to output telegrams via another input/output port, which is stored in a routing table in the memory unit. The processor unit is further configured to determine whether a telegram is a protocol telegram received via an input/output port for which it is preset that no protocol subscriber is connected, 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.Type: ApplicationFiled: October 21, 2021Publication date: February 3, 2022Inventors: Holger Büttner, Dirk Janssen, Erik Vonnahme, Thomas Rettig, Hans Beckhoff, Thorsten Bunte, Johannes Beckhoff

Patent number: 10848419Abstract: 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.Type: GrantFiled: December 13, 2017Date of Patent: November 24, 2020Assignee: Beckhoff Automation GmbHInventors: Thorsten Bunte, Holger Büttner, Erik Vonnahme, Dirk Janssen, Thomas Rettig, Hans Beckhoff

Patent number: 10735219Abstract: 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.Type: GrantFiled: April 20, 2018Date of Patent: August 4, 2020Assignee: Beckhoff Automation GmbHInventors: Thorsten Bunte, Holger Büttner, Erik Vonnahme, Dirk Janssen, Thomas Rettig, Hans Beckhoff

Patent number: 10735218Abstract: 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.Type: GrantFiled: July 10, 2019Date of Patent: August 4, 2020Assignee: Beckhofff Automation GmbHInventors: Thorsten Bunte, Holger Büttner, Dirk Janssen, Thomas Rettig, Hans Beckhoff, Erik Vonnahme

Patent number: 10484520Abstract: 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.Type: GrantFiled: May 18, 2018Date of Patent: November 19, 2019Assignee: Beckhoff Automation GmbHInventors: Thorsten Bunte, Holger Büttner, Erik Vonnahme, Dirk Janssen, Thomas Rettig, Hans Beckhoff

Patent number: 10271249Abstract: A network includes a first network participant connected via a first connection to a further network participant. The first network participant receives a data message containing information that a parameter must be set to a first value, via the first connection. The first network participant checks whether it is connected via a second connection to a still further network, and whether the parameter is not set to the first value in the second connection. 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.Type: GrantFiled: February 15, 2016Date of Patent: April 23, 2019Assignee: BECKHOFF AUTOMATION GMBHInventors: Thorsten Bunte, Holger Büttner, Erik Vonnahme, Dirk Janssen, Thomas Rettig, Hans Beckhoff
