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.

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: 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 planar drive system includes a stator module and a rotor. The stator module has a stator assembly with at least one coil arrangement that can be energized to generate a stator magnetic field above a stator surface, and a magnetic field sensor. The rotor has a magnet arrangement and can be moved above the stator surface via interaction between the stator magnetic field the magnet arrangement. The rotor can be used as an input device or output device, or both. A controller can compare the position of the rotor magnetic field detected with the sensor to the position expected based on energization of the coil arrangement, to determine any deviation of the expected position as an external movement, and to recognize an input thereby. The controller can control an output via a predetermined movement of the rotor, and to energize the coil arrangement so the rotor moves as defined.
