A method for operating a communications network that includes a computing system, at least one intermediate control unit, and at least one execution unit for each intermediate control unit. The at least one intermediate control unit is communicatively connected to the computing system using a first communication system. Each of the at least one execution unit is communicatively connected to the associated intermediate control unit using a second communication system, which is a master-slave communication system, and used as a slave. A message configuration table for each second communication system is stored in the computing system, the message configuration table indicating a temporal sequence of data to be transmitted on the second communication system in question. For a communication with one of the execution units, data are sent from the computing system, via the associated intermediate control unit, to the execution unit according to the associated message configuration table.

A method for operating a communications network that includes at least two users that are communicatively connected to one another via a descriptor-based communication system such as Ethernet. For writing data from a writing user into a user to be written, receive descriptors and data are transmitted from the writing user to the user to be written, in the user to be written, the data being written according to the received receive descriptors, and/or for reading data by a reading user from a user to be read, transmit descriptors are transmitted from the reading user to the user to be read, data being read by the user to be read according to the received transmit descriptors and transmitted to the reading user. A communications network and users are also described.

A method for transmitting a data transfer block, the data transfer block comprising at least one data segment having a predetermined number of one or more data units, to be identified using validity information, and a header segment, the method including the following steps: a) writing a data unit into a first area of an output register predetermined for the data segment, from which the buffered data transfer block is transmitted via a bus system at a predetermined transmission instant with the aid of a time multiplexing method; b) writing a validity datum, implemented as a toggle bit or as an N-bit counter, into a second area of the output register predetermined for the header segment, the particular validity datum specifying the validity of the corresponding written data unit; c) enabling the data transfer block buffered in the output register for transmission, after the particular data unit and the corresponding validity datum are written into the output register; d) repeating steps (a) through (c) until the predetermined number of the data units and the corresponding validity data are written or the predetermined transmission instant is reached; and e) transmitting the enabled data transfer block buffered in the output register at the transmission instant.

A method, a CAN bus driver and a CAN bus system for the recovery of a clock frequency of a CAN bus, which couples a master device, that has a clock generator for providing the clock frequency, to at least one slave device. A phase-locked loop is used in the slave device, in this context, which utilizes a predetermined bit pattern, that is extracted from a frame sent by the master device via the bus system, as reference signal.

A Method and an apparatus for providing control parameters to or within a control system for controlling a fuel injection system are described. The method is characterized in that a plurality of control parameters is transmitted to storage means ( ) within the control system by transmission means ( ). The transmitted control parameters are stored within the storage means ( ). Selection parameters are transmitted to selection means ( ) within the control system by transmission means ( ). Stored control parameters are selected in accordance with transmitted selection parameters by the selection means ( ). And the selected parameters are utilized for controlling elements within the control system. The apparatus is in particular eligible for usage with a inventive method and is characterized in that a control unit (D) and an activation IC (E) are connected to each other by transmission means ( ). Storage means ( ) are implemented in the activation IC (E). And selection means ( ) are implemented in the activation IC (E).

A method for timed measurement of a voltage across a device in a charging circuit of a piezoelectric element. The voltage across the device is sensed and read at a predefined time in synchronization with an injection event of the at least one piezoelectric actuator. The device may be the piezoelectric element or a buffer capacitor.
