摘要： 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.

摘要： An arm module includes a housing with a first connection side controllably rotatable relative to a second connection side, about an axis of rotation. The first connection side has a rotatable first connection device. The second connection side has a second connection device fixed to the housing, with a rotation-compatible data transmission device for transmitting data signals along at least one transmission path between the first and second connection sides. The transmission path includes at least one wireless transmission sub-path for wireless transmission of data signals, and at least one wire-guided transmission sub-path for wire-guided transmission of data signals. The rotation-compatible data transmission device includes at least one first wireless transmission unit and at least one second wireless transmission unit, interconnected via the transmission path and arranged to wirelessly transmit and receive data signals along the wireless transmission sub-path. An industrial robot can have a plurality of such arm modules.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
