Publication number: 20190363906Abstract: 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: ApplicationFiled: July 10, 2019Publication date: November 28, 2019Inventors: 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

Publication number: 20180241585Abstract: 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=0, . . . , N?1). Each of the N messages contains a field defining a waiting time assigned to the respective message W_I=T_(N?1)?T_I+?W_I (I=0, . . . ,N?1), where ?W_I is a non-negative tolerance 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: ApplicationFiled: April 20, 2018Publication date: August 23, 2018Inventors: Thorsten Bunte, Holger Büttner, Erik Vonnahme, Dirk Janssen, Thomas Rettig, Hans Beckhoff

Publication number: 20180176132Abstract: 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: ApplicationFiled: December 13, 2017Publication date: June 21, 2018Inventors: Thorsten Bunte, Holger Büttner, Erik Vonnahme, Dirk Janssen, Thomas Rettig, Hans Beckhoff

Patent number: 9991981Abstract: A method for operating a node in a communications network comprises the following steps: The node receives a reference time via the communications network. A transmit clock of the node, which was determined for an earlier clock cycle on the basis of a local clock of the node, is compared with the reference time. The local clock of the node is corrected on the basis of the comparison result. On the basis of the corrected local clock a transmit clock is determined to be used by the node for the current clock cycle.Type: GrantFiled: January 11, 2016Date of Patent: June 5, 2018Assignee: BECKHOFF AUTOMATION GMBHInventors: Thorsten Bunte, Holger Büttner, Dirk Janssen, Erik Vonnahme, Thomas Rettig, Hans Beckhoff

Patent number: 9544258Abstract: 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.Type: GrantFiled: June 23, 2015Date of Patent: January 10, 2017Assignee: BECKHOFF AUTOMATION GMBHInventors: Thorsten Bunte, Holger Büttner, Erik Vonnahme, Dirk Janssen, Thomas Rettig, Hans Beckhoff
