An integrating model for a technical system composed of at least one of a machine, a component of a machine, and a technical process includes a machine-machine interface, and a plurality of individual models having each assigned a raw model and a data pre-processing, wherein different individual models model different parts of the technical system and have different raw models and a different data pre-processing, and wherein at least one of the individual models is interchangeable for a part of the technical system.

A method for automated configuration of a tester equipped for testing a control unit. A first and second model of technical systems being executed in the tester. The execution of the models taking place periodically with defined sampling rates. An FPGA executes the first and/or the second model and a CPU executes the first or the second model. A first individual sampling rate is allocated for the first model and a second individual sampling rate is allocated for the second model. The first model is assigned for execution on either the CPU or the FPGA and the second model is assigned for execution on either the CPU or the FPGA. The tester is automatically configured for execution of the first model with the first allocated sampling rate on the FPGA or the CPU and of the second model with the second allocated sampling rate on the FPGA or the CPU.

A method for configuring a real or virtual electronic control unit, wherein a control unit software is executed on the control unit, and the control unit software comprises a basic software layer, the basic software layer is configured by a module configuration file by setting values of parameters, the scope of the configurable parameters being defined in a first module definition file which contains the identifiers of the configurable parameters. The first module definition file is replaced by a second module definition file, and a conversion of the first module configuration file into a second module configuration file takes place.

A controller hardware in the loop (CHIL) interface is disclosed. The CHIL interface comprises software and hardware that redirects a signal flow, including modulation signals and measurements exchanged between controller logic and a power electronics converter (PEC), to a CHIL port. Accordingly, the CHIL port provides access to the controller logic, at a digital level, throughout phases of the controller's lifetime (i.e., design, installation, maintenance, upgrade). Thus, the CHIL interface facilitates the use of PEC simulators for testing. The CHIL interface can detach the actual PEC from the control logic so testing can be performed with or without an operating PEC and can avoid the need for dedicated and error prone signal conditioning circuitry that is external to the controller.

A simulation apparatus for simulating a peripheral circuit arrangement connected to a regulating device and has a first current controller for influencing a first load current and a second current controller for influencing a first source current. The first current controller is controlled by a model code and used to set the first load current, and the first load current is routed to a first load connection of the regulating device. The second current controller is controlled by the model code and used to set the first source current, which is routed to a first supply connection of the regulating device. The model code influences the model code on the first current controller and the second current controller allows the first load current to be recovered at least proportionally from the first source current and/or the first source current to be recovered at least proportionally from the first load current.

A configuration system for configuring a test system suitable for testing an electronic control unit, wherein a configuration diagram has a plurality of hierarchy elements, and a hierarchy element either has one hierarchy element or multiple hierarchy elements or no hierarchy element. The hierarchy element has an identifier, and wherein a hierarchy element has port(s) or no port, and wherein at least one hierarchy element is assigned to a functional property of the test system to be configured, wherein in an expanded view mode, the hierarchy elements are displayed at least partially nested and the ports and identifiers are shown one below the other, wherein in an at least partially collapsed view mode, a first set of hierarchy elements is shown such that the identifiers are shown side by side, wherein the ports and identifiers remain visible and the hierarchical relationship of the hierarchy elements remains displayed.

A method is disclosed for synchronizing a checking apparatus, in which the checking apparatus is configured for testing at least one first electronic closed-loop control unit. Further disclosed is a checking apparatus which is transferable to a synchronized state. Additionally disclosed is a composite system which includes at least two checking apparatuses. Also disclosed are a checking apparatus for testing at least one first closed-loop control unit, and a composite system including at least one checking apparatus and a further checking apparatus, the latter checking apparatus being configured to have the same effect as the first checking apparatus.

A system and method for online simulation of a controlled machine or process utilizes a simplified model of the system dynamics and may be used with hardware in the loop to evaluate performance of the controlled system or with software in the loop to perform commissioning of the control program prior to completion of the mechanical installation. The simplified model includes dominant order dynamics of the controlled system such as the inertia of the system and a damping factor. Further, the online simulation is scheduled to execute at an update rate slower than the update rate of the control loops within the motor drive. The simplified model and reduced update rate reduce the computational burden on the processor such that the simulation may be performed either on the industrial controller or on the motor drive.

An electronic control unit (ECU) for transmitting large data in a hardware-in-the-loop (HiL) simulation environment, a system including the same and a method thereof are provided. The electronic control unit for executing a HiL simulation includes an interface transmitting/receiving data associated with a simulation in link with a hardware-in-the-loop (HiL) simulator, a data storing unit storing data generated by executing the simulation, and a transmission agent fragmenting the stored data into multiple data and transmitting the multiple data and transmitting one data segment according to a fragmented order whenever repeatedly executing the simulation.

A handheld field maintenance tool includes a training mode. The handheld field maintenance tool has a process communication module operably coupleable to a field device, a user interface, and a controller coupled to the process communication module and the user interface.
