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 planar drive system has at least one stator assembly with a plurality of coil groups for generating a stator magnetic field, a stator surface above the stator assembly, and first and second rotors. The rotors each have a plurality of magnet units for generating a rotor magnetic field. The rotors can be moved above the stator surface in first and second directions, with the aid of an interaction of the stator magnetic field with the rotor magnetic field. A connection can be formed between the rotors with the aid of a coupling device. A controller is arranged to output control signals to the stator assembly. The stator assembly is configured to energize the coil groups on the basis of the control signals so that movements of the rotors, coordinated with one another with respect to the coupling device, are carried out with the aid of the stator magnetic field.

Abstract: A switch-cabinet system comprises a base module with a base housing and at least one functional module with a functional housing. A functional connection element is arranged in the functional housing in the area of a first through-opening on a bottom side of the functional housing. A base connection element is arranged in the base housing in the area of a second through opening on a top side of the base housing. The bottom side of the functional housing rests against the top side of the base housing. The functional and base connection elements engage and form an interface. The system also includes a sealing insert having a frame with a functional section engaging the functional housing and a base section engaging the base housing. The functional section abuts an inner wall of the functional housing. The base section abuts a wall of the base housing defining the second through-opening.

Abstract: A method is provided for processing an object with the aid of a planar drive system. The planar drive system comprises at least one stator assembly, each having a plurality of coil groups for generating a stator magnetic field, a stator surface above the stator assembly, and at least one rotor comprising a plurality of magnet units for generating a rotor magnetic field. The planar drive system further comprises at least one rotational position, where the rotor is rotatable about a rotational axis perpendicular to the stator surface in the rotational position. The rotational position is determined based on a point of contact of four stator assemblies. The method comprises energizing the coil groups in such a way that the rotor moves to the rotational position, energizing the coil groups in such a way that the rotor rotates, and processing of the object with the aid of the rotor rotation.

Abstract: At least one distribution node with a plurality of input/output interfaces is provided in an automation communication network. Data is exchanged via telegrams with priority levels. The distribution node interrupts transmission of a telegram having a first priority level if a telegram with a second, higher priority level is received. The distribution node terminates the interrupted telegram, which forms a first fragment defined by sending first fragmentation information at the end of the first fragment. A part that has not been sent forms a second fragment. The distribution node stores the second fragment together with second fragmentation information. After sending the telegram having the second, higher priority level, the distribution node sends the second fragment together with the second fragmentation information. A node, for which the telegram having the first priority level is intended, assembles the first and second fragments on the basis of the first and second fragmentation information.

Abstract: A communications network having a master subscriber M and at least one slave subscriber. At least one distribution node CU1, CU2, CU3, CU4 is provided which has a plurality of input/output interfaces, each of which is connected to a network segment, the master subscriber M arranged in a first network segment M1 and the slave subscriber arranged in a second network segment S1, S2, S3, S4, S5. Data is exchanged between the master subscriber M and the slave subscriber in the form of telegrams initiated by the master subscriber. The telegrams to be sent from the slave subscriber to the master subscriber are each assigned control data containing a forwarding time information when the corresponding telegram is to be output from the distribution node via the input/output interface in the direction of the first network segment comprising the master subscriber, the forwarding time information determined by the master subscriber M.

Abstract: A communications network comprises a plurality of participants. A first participant transmits a message repeating sequence of N≥2 successive messages to a second participant. An action which can be performed by the second participant is assigned to each message in the sequence. The first participant begins to transmit one of the N messages at N successive transmission times T_I (I=0, . . . , N−1). Each of the N messages contains a field defining a waiting time assigned to the respective message W_I=T_(N−1)−T_I+ΔW_I (I=0, . . . ,N−1), where ΔW_I is a non-negative tolerance time. The second participant selects one message from among the messages in the sequence which are successfully received by the second participant as a useful message, measures a time elapsed since reception of the useful message, and performs the action assigned to the useful message when the elapsed time has reached the assigned waiting time.

Abstract: 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.
