  • Patent number: 11765124
    Abstract: A receiving logic of a network subscriber can be configured in a first filter setting to forward telegrams having first and second addressing techniques to first and second processing units, with a transmitting logic configured to forward the telegrams to a transmitting port. In a second filter setting, the receiving logic can be configured to duplicate the telegrams and forward to the first and second processing units, with the first processing unit configured to discard telegrams using the second addressing technique and the second processing unit configured to discard telegrams using the first addressing technique. The receiving logic of a third filter setting can be configured to duplicate telegrams and forward to the first and second processing units, with the transmitting logic configured to forward only telegrams using the first addressing technique from the first processing unit, and only telegrams using the second addressing technique from the second processing unit.

  • Patent number: 11758024
    Abstract: In an automation network comprising a plurality of network segments, fragmenting subscribers that support a fragmentation method as well as standard subscribers that do not support the fragmentation method can be provided for in the network. A distribution node in the automation network has at least one input/output interface that is in communication with a network segment. The switching unit in the distribution node checks whether a subscriber in a network segment to which a telegram is to be sent supports the fragmentation method, and whether the telegram to be sent is fragmented. If the subscriber does not support the fragmentation procedure and the telegram to be sent is fragmented, the switching unit in the distribution node assembles the telegram fragments to form the telegram and then sends the assembled telegram on to the subscriber.

  • Patent number: 11539549
    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.

  • Publication number: 20220271913
    Abstract: A method for synchronizing time in an Ethernet-based network having a master network subscriber and a slave network subscriber includes sending out a first telegram via the master network subscriber, where the slave subscriber receives the first telegram at a first receipt time value of a local system time and stores the first receipt time value. The method can also include reading out the first receipt time value via the master subscriber, sending out a second telegram by the master subscriber, where the slave subscriber receives the second telegram at a second receipt time value of the local system time and stores the second receipt time value, and reading out the second receipt time value via the master network subscriber. A speed parameter of the local system time can be calculated from the receipt time values via the master network subscriber, and transmitted to the slave subscriber.

  • Patent number: 11411769
    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.

  • Publication number: 20220247728
    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.

  • Patent number: 11398919
    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.

  • Patent number: 11327800
    Abstract: To control a technical process comprising a control task for independently controllable modules, modules are each assigned to a computing core on a controller with a plurality of computing cores. The technical process is connected to the controller via at least one communication connection. In a first time segment, the controller provides read-in input data of the modules for the respectively associated computing core. Subsequently, synchronization of the computing cores to which modules are assigned is carried out by the controller. In a second time segment, the computing cores process the input data of the modules to generate output data for the modules, wherein each computing core signals the end of processing. As soon as all computing cores have signaled the end of processing, the output data are provided in a third time segment by the controller in order to be provided to the modules on the communication connection.

  • Publication number: 20220103485
    Abstract: 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.
