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.

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.

Abstract: A method is related for operating a modular robot. The modular robot comprises a robot base, at least a robot arm arranged on the robot base and a controller. The robot arm comprises a plurality of modularly arrangeable arm modules. The controller carries out steps described herein. Allocation information is received from each of the arm modules in an allocation determining step. In an arm module base data determining step, arm module base data is determined for each arm module based on the allocation information. Further, a configuration of the modular robot is created from the association information and the arm module base data of each arm module in a configurating step, where the configuration is used to control the robot arm.

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.

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.

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.

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.
