摘要： A planar drive system comprises a stator and a rotor. The stator comprises a plurality of energizable stator conductors. The rotor comprises a magnet device having at least one rotor magnet. A magnetic interaction can be produced between energized stator conductors of the stator and the magnet device to drive the rotor. The stator is configured to carry out energization of the stator conductors so that an alternating magnetic field can be generated via the energized stator conductors. The rotor comprises at least one rotor coil in which an alternating voltage can be induced due to the alternating magnetic field. The planar drive system is configured to transmit data from the stator to the rotor, and the stator is configured to temporarily influence the energization of the stator conductors in order to temporarily cause a change with respect to the alternating voltage induced in the at least one rotor coil.

摘要： 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.

The linear motor comprises a stator and a first and a second rotor. The stator has a plurality of drive coils that are arranged along the guide rail individual motor modules comprise a plurality of drive coils. The first rotor is arranged on the first carriage and the second rotor is arranged on the second carriage. The first carriage has a first magnetic field generator. The second carriage has a second magnetic field generator. The first magnetic field generator differs from the second magnetic field generator at least in terms of its magnetic vector field, wherein the magnetic fields of the magnetic field generators are detected to identify the corresponding carriage.

摘要： An automation system has a master control unit, a first radio subscriber, a first radio device and a clock master. The first radio device has a first synchronization element, a first radio module and a first connection for the bus system. The first radio module can establish a radio connection to the first radio subscriber for data exchange with a bus system provided by the master control unit. The first radio connection has a first radio channel with a first frequency range. The first synchronization element is set up to output a synchronization signal to the first radio module, based on a signal received from the clock master via the first connection. The first radio module is set up to change a frequency of the first radio channel based on the synchronization signal, within the first frequency range, on the basis of a first hopping table.

摘要： A method for controlling an automation system with visualization of program objects of a control program of the automation system, comprises determining a pointer address of the pointer element, determining a first address offset of the pointer address, identifying a program object that is spaced apart from the first memory location of the program state by the first address offset according to the arrangement structure of the program state as a first program object, the memory address of which in the first memory area corresponds to the pointer address of the pointer element, identifying the first program object with the pointer object referenced by the pointer element, determining a fully qualified designation of the identified pointer element, and displaying the fully qualified designation of the pointer object referenced by the pointer element on a display element connected to the controller. An automation system carries out the method.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A stator assembly for a planar electrical motor includes coil conductors arranged in a stator layer, elongated in a first direction and arranged side by side in a second direction perpendicular to the first direction. The coil conductors are connected to form a three-phase system, with a first forward conductor and first return conductor of the first phase connected in series to the first forward conductor, a second forward conductor and second return conductor of the second phase connected in series with the second forward conductor, and a third forward conductor and third return conductor of the third phase connected in series with the third forward conductor. The three-phase system has first and second opposite sides. The first forward conductor and the first return conductor are electroconductively connected in series by first and second horizontal connecting conductors arranged in the stator layer on the second and first side, respectively.
