LabVIEW Simulation Interface Toolkit

The National Instruments LabVIEW Simulation Interface Toolkit gives control system design and test engineers a seamless link between LabVIEW and The MathWorks Simulink® software. With these integrated tools, engineers can build custom LabVIEW user interfaces to interactively view and control data in the Simulink® environment. By extending your Simulink® simulation software with LabVIEW, you can use The MathWorks Real-Time Workshop® to import the model into LabVIEW to integrate with real-time (RT) hardware I/O. With these capabilities, you can take a control model from software verification to real-world prototyping and hardware-in-the-loop simulation.

Descriptions

The Simulation Interface Toolkit provides methods for:
- Creating a LabVIEW user interface for a Simulink® model.
- Converting the Simulink® model into a dynamic link library (DLL).
- Mapping CAN, FPGA, or Analog I/O to model imports and outports
- Running the model on an RT target for HIL simulation or rapide control prototyping.

By combining the capabilities of Simulink® and Real-Time Workshop® with LabVIEW, the Simulation Interface Toolkit helps you import simulation models into LabVIEW.

Create a LabVIEW user interface for a Simulink model

On the host computer, you create a host VI. The front panel of the host VI provides the user interface to the Simulink® model. This front panel contains LabVIEW controls and indicators that correspond to the Simulink® parameters and sinks that you want to modify and display. You can change the values of controls and immediately view the results of that change in the indicators.

The block diagram of the host VI contains the code that connects front panel controls and indicators with model parameters and sinks. You use the SIT Connection Manager dialog box to generate this block diagram code automatically.

The Simulation Interface Toolkit installs a User Interface palette that contains VIs with which you can build customized block diagrams. You can use these User Interface VIs to replicate the block diagram code generated by the Simulation Interface Toolkit.

Using the Simulation Interface Toolkit, you can connect multiple VIs created on the host computer to the same Simulink® model. You also can connect multiple Simulink® models on the same computer to a single VI created on the host computer.

Convert a Simulink model into a dynamic link library (DLL)

You can run a Simulink® model on an RT target. For this, you use Real-Time Workshop® to convert the model file (.mdl) into C code. Real-Time Workshop® then uses Microsoft Visual C++ to compile the C code into a model DLL that LabVIEW calls. The Simulation Interface Toolkit automatically builds a model VI that calls the model DLL.

Run a simulation model on an RT target

When you create the model DLL, you create a simulation model that can run on an RT target. When you run the host VI, you can choose to download the model DLL and model VI to an RT target. The Simulation Interface Toolkit then starts the SIT Server on the RT target. The host VI communicates with the model VI and model DLL through the SIT Server.
