Abstract: A method for processing telegrams in an automation network provides a master subscriber to at least partially encrypt and output telegrams, respectively, to another subscriber. The other subscriber comprises an input port, a receiving logic connected to the input port, a decryption unit connected to the receiving logic, and a processing unit connected to the decryption unit and the receiving logic. The receiving logic is configured, when a telegram at least partially encrypted by the master subscriber is present at the input port, to forward an encrypted portion of the telegram to the decryption unit. The decryption unit is configured to decrypt the encrypted portion of the telegram with a key, and to forward the encrypted portion to the processing unit for processing. If an unencrypted telegram is present at the input port, the receiving logic is configured to forward the unencrypted telegram to the processing unit for processing.

Abstract: A method is provided for operating an automation system which comprises a drive system and an optical projection unit. The drive system comprises a movable rotor, where the rotor can be driven with the aid of a drive. A control system of the automation system carries out the following steps of determining a position information of a rotor, linking an object to be displayed to the rotor, rendering a projection to be displayed by the optical projection unit on the basis of the position information of the rotor and the object to be displayed, and outputting the rendered projection to the optical projection unit, so that the optical projection unit outputs the rendered projection on a surface and/or on the rotor or on a superstructure or superstructures of the rotor, and/or on transport goods of the drive system.

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 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.

Abstract: A network distributor has a plurality of input-output ports, a processor unit, and a memory unit. The ports connect network subscribers via a data line network, where the network subscribers include protocol subscribers to process telegrams as protocol telegrams. The processor unit receives telegrams via one port and outputs telegrams via another port, which is stored in a routing table in the memory unit. The processor unit further determines whether a telegram is a protocol telegram received via a port for which no port identifier is stored in the memory unit, 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.

Abstract: A method is provided for processing an object using a planar drive system having 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 at least one rotor with a plurality of magnet units for generating a rotor magnetic field. A processing element is arranged above the stator surface. The planar drive system has at least one rotational position, where the rotor can be rotated about an axis perpendicular to the stator surface. A spatial arrangement of the processing element is predetermined by the rotational position. The method comprises energizing the coil groups so a rotor with the object arranged on the rotor moves to the rotational position, energizing the coil groups so the rotor rotates, and processing the object with the aid of the rotor rotation, where the processing element acts upon the object.

Abstract: A method for controlling a planar drive system includes identifying a preferred stator module direction with a preferred magnetic field or sensor direction, and identifying a preferred mover direction with a respective other of the preferred magnetic field or sensor direction; setting a magnetic orientation field with a magnet device; recording at least a measurement value of the magnetic orientation field with a magnetic field sensor device; determining an alignment of the preferred mover direction relative to the preferred stator module direction based on the measurement value of the component of the magnetic orientation field parallel to the preferred sensor direction; and determining a first orientation of the mover on the stator module, on the basis of the alignment of the preferred mover direction relative to the preferred stator module direction. The application also relates to a planar drive system.

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.
