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 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 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: 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.

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.

Abstract: A sealing sleeve for a stator of an electrical machine is disclosed. The sealing sleeve is configured to provide that a coolant flowing around the stator coils follows a predefined, serpentine coolant path. The sleeve has two sealing rings arranged on the stator with the coils of the stator lying between them. Each sealing ring includes a hard component and a soft component. The sleeve is arranged on the stator such that sealing sections of the soft component bear against the surfaces of the stator coils and adapt to the coil surfaces. As such, no coolant may pass between the coils and the sealing rings at these sealing locations thus formed, and therefore the desired coolant flow is guaranteed. Furthermore, the sealing rings are configured such that alternately for each coil only one of the sealing rings has a sealing section so that ultimately the serpentine coolant flow is achieved.

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 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 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 network distributor comprises a plurality of input/output ports, a processor unit, and a memory unit. The input/output ports are configured to connect network subscribers via a data line network, where the network subscribers comprise protocol subscribers configured to process telegrams configured as protocol telegrams. The processor unit is configured to receive telegrams via one input/output port and to output telegrams via another input/output port, which is stored in a routing table in the memory unit. The processor unit is further configured to determine whether a telegram is a protocol telegram received via an input/output port for which it is preset that no protocol subscriber is connected, 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.
