A method for configuring and parameterizing field bus subscribers interconnected via a field bus, wherein a first field bus subscriber provides and/or receives process data and a second field bus subscriber allows a user program to run, where a topology is determined by a configuration tool with configuration parameters of the field bus subscribers in a configuration file, the first field bus subscriber is parameterized for subsequent communication via the field bus with a configuration data set including a first part of the configuration file, from the configuration file and further code portions from a program library, an object-orientated class is generated with elements and functions for communication between the first and second field bus subscribers, and the class is instanced in the user program of the second field bus subscriber, the functions being used for communication during execution of the user program to permit access to the process data.

Interface module and method for configuring and parameterizing a field bus user, wherein to facilitate a configuration and parameterization of a field bus user logical addresses on the side of an engineering system are transformed with a transformation device into virtual addresses, where whether virtual addresses are present in a received virtual configuration file is recognized in an interface module via a recognition device, a signal is triggered when addresses are present in the received virtual configuration file to ensure the virtual configuration file is adopted and stored in a non-volatile manner in a configuration store within the interface module, and where the virtual addresses are transformed in the interface module via a reverse transformation device back into physically present addresses, whereby for a data exchange of the process data of the module slot, on request by further field bus users, the process data in the module slot is addressed.

An automation system includes a first/second control devices having first/second field bus terminals, a field bus, a peripheral assembly having at least one input/output peripheral module for connection to sensors and/or actuators, where the peripheral assembly includes an interface module having a third field bus terminal for communication to and/or from the control devices, and where the interface module includes at least one input/output module storing interconnect information that creates an association between inputs/outputs of the at least one input/output peripheral module and the control devices, and where the interface module additionally includes a virtual data set module in which a data set receiving module is associated with the first control device to which a data set is writable by the first control device, and includes a data set transmitting module associated with the second controller from which the data set is retrievable by the second control device.

Automation system and method for operation of the system

An automation system includes a first control facility with a first fieldbus connection, a second control facility with a second fieldbus connection, a fieldbus, a peripheral board with at least one I/O peripheral module, wherein the peripheral board has an interface module with a third fieldbus connection, where the interface module has at least one I/O module which stores interconnection information featuring an assignment of input/outputs of the I/O peripheral module(s) to the control facilities, where the interface module additionally has a virtual I/O module, in which an output region is assigned to the first control facility, and furthermore an input region is assigned to the second controller, and where the virtual I/O module is configured such that the output data is copied from the output region of the first control facility into the input region as input data for the second control facility.

Automation system and method for operation of the automation system

In a process for controlling an internal combustion engine () having at least one cylinder (Zto Z) in which a combustion chamber () is formed, fuel is injected in at least two modes of operation. The process has the following steps: relative to an operating point determined by at least one operating variable (), an operating mode quality value is calculated for each of at least two operating modes, an operating mode (OPMOD_SEL) is selected from the at least two operating modes depending on the operating mode quality values, and correcting variables are determined and set depending on the at least one operating variable () and the selected operating mode (OPMOD_SEL).

Process and device for controlling an internal combustion engine

In a method for controlling an internal combustion engine () during which two operating modes (OPMOD) are switched between under the permissible variation of at least one first and one second torque manipulated variables if, as a result, a torque-neutral changing over into the target operating mode (OPMOD_F) can be achieved within a cylinder segment. If the predetermined changing over condition is fulfilled, a torque-neutral changing over occurs while varying the at least first and second torque manipulated variables. If the predetermined changing over condition is not fulfilled, the initial operating mode (OPMOD_I) is maintained and at least one of the at least first and second torque manipulated variables and an at least one third torque manipulated variable are torque neutrally varied until the change over condition is fulfilled.

Method and device for controlling an internal combustion engine when changing operating modes

In an adaptive positioning method for an actuator, in particular, for a throttle butterfly on an internal combustion engine, during the adaptive positioning method, after a request for a set position and selection of a pilot value a corresponding pilot position for the actuator is adopted. The pilot position is adjusted until said position corresponds to the requested set position. The control value actually required or this set position is subsequently measured and recorded as corrected pilot value for the corresponding set position.

Adaptive positioning method for an actuator

An internal combustion engine has a plurality of cylinders having combustion chambers and each being associated with a spark plug designed for igniting a mixture of air and fuel in the combustion chamber, and at least two adjusting devices for adjusting the air supply to the combustion chambers of the different cylinders. To control the internal combustion engine, an individual ignition angle is detected for each group of cylinders to which the same air mass per working cycle is respectively supplied and during the respective working cycles of which the same loss torque is decisive. The decisive loss torque is the one associated with the cylinder that is in its intake cycle during the respective working cycle of the respective cylinder of the respective group. The individual ignition angle for each group is detected as a function of the decisive loss torque for the respective group.
