Abstract: A microcontroller unit of an input/output module checks whether a communication connection can be set up from the microcontroller unit to a communication subscriber of a data cable plugged into the one portion of a electrical plug connection of the input/output module, wherein the microcontroller unit of the input/output module actuates DC voltage supplies of the input/output module such that the DC voltage supplies apply a respective DC voltage to applicable electrical contacts of electrical contact elements of the input/output module only if the check has revealed that a communication connection has been able to be set up to the communication subscriber of the data cable.

Abstract: 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.

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: A method is provided for communicating between passive subscribers of a bus system. A first passive subscriber encodes an original static pattern in a first transmit SERDES element and encodes original user data in a time-synchronized manner with the original static pattern in a second transmit SERDES element. The second passive subscriber receives the encoded static pattern and user data, and generates a sampling clock having a first phase offset and a clock synchronous with a transmit-receive clock having a second phase offset, from the encoded static pattern. The second passive subscriber decodes the encoded static pattern using a first receive SERDES element and the encoded user data, using a second receive SERDES element to obtain a receive data word. The first receive SERDES element and the second receive SERDES element are operated based on the sampling clock, and the receive data word is output synchronously with the synchronous clock.

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.

Abstract: 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.

Abstract: 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.

Abstract: A network subscriber of an automation communication network is provided to exchange data with further network subscribers in the automation communication network at a predetermined clock frequency. The network subscriber has an internal clock for synchronizing the data exchange with at least one other network subscriber. The internal clock is embodied to provide a time as an integer count value. The clock frequency is determined in such a way that a period duration per clock pulse cannot be represented as an integer count value by the internal clock. A method of operating the network subscriber in the automation communication network comprises the following method step: the internal clock is incremented with a predetermined sequence of integer increments. The sequence of integer increments is predetermined such that a sum of the integer increments corresponds to an integer multiple of the period duration.
