Automating the Installation of NI Products


The NI LabVIEW Simulation Interface Toolkit gives control system design and test engineers a link between the NI LabVIEW graphical development environment and The MathWorks, Inc. Simulink®application software. With the LabVIEW Simulation Interface Toolkit, you can easily build custom LabVIEW user interfaces to view and control your simulation model at run time. This toolkit also provides a plug-in for use with The MathWorks, Inc. Real-Time Workshop® (Simulink Coder®), so you can use LabVIEW to connect your model developed in the Simulink environment to the real world through a variety of real-time I/O platforms (requires the LabVIEW Real-Time Module). With these capabilities, you can easily take your models from software verification to real-world prototyping and hardware-in-the-loop simulation.

Supported Operating Systems

You can run the LabVIEW Simulation Interface Toolkit installer on the following operating systems:

  • Windows 7 (32-bit and 64-bit)
  • Windows Vista (32-bit and 64-bit)
  • Windows XP SP2 (32-bit)
  • Windows Server 2003 R2 (32-bit)
  • Windows Server 2008 R2 (64-bit)

To request additional LabVIEW 2012 Platform DVDs, refer to the National Instruments Web site

Note If you purchased this product with an NI Software Suite or NI Product Bundle, use the installation media that shipped with your purchase to install this product.

Upgrading from SIT 2.0.x/3.0.x/4.0/5.0.x/2009/2010/2011

  • Load a host VI saved in SIT 3.0.x/4.0 and launch the SIT Connection Manager dialog box. Click the OK button to apply new settings. The conversion process preserves control/indicator mappings and all block diagram code. You will lose changes to SIT 3.0.xdriver VI, but SIT 5.0.1 maintains hardware mappings. If the path to your model is invalid, SIT 5.0.1 prompts you to specify a valid path.
  • SIT 3.0.x driver VIs are not supported in SIT 5.0.1. If you are not using the SIT Connection Manager you will need to manually upgrade the driver VI. Refer to one of the examples for the correct driver VI structure.
  • SIT 5.0.1 does not convert driver VIs that SIT 2.0.x generated. Use the SIT Connection Manager dialog box to build a new driver VI for use in real-time simulations.
  • SIT 5.0.1 does not convert host VIs that SIT 2.0 generated.
  • The Simulation Interface Toolkit 4.0 deprecated the following VIs: SIT Execute Task and SIT Synchronize Base Rate.
  • The Simulation Interface Toolkit 5.0.1 relies heavily upon the SIT Connection Managerdialog box. National Instruments recommends you use this dialog box to create host VIs and driver VIs.
  • When running a simulation in Simulation Environment, the SignalProbe blocks from SIT 3.0.x/4.0 do not recognize tuneable variables specified through Data Objects. To be able to tune variables specified as tuneable through Data Objects, you must delete and re-add the SignalProbe block.
  • Update any custom FPGA bitfiles and VIs you developed in SIT 3.0.x/4.0 to the new FPGA VI template and recompile them.
  • SIT Write Log Settings to Configuration and SIT Write Playback Settings to Configuration in the User API have a new required input for Model Path.
  • The Simulation Interface Toolkit 5.0/5.0.1/2009/2010/2011 VIs can be used in LabVIEW 2012 Simulation Interface Toolkit without any modification.
  • The LabVIEW 2012 Simulation Interface Toolkit supports the 2011a software release of The Mathworks, Inc. MATLAB®, Simulink®, Real-Time Workshop®, and Stateflow® software.

What's New in 2012

The LabVIEW 2012 Simulation Interface Toolkit includes the following new features:

  • Updated Support for The MathWorks, Inc. Software

Support for Real-Time Targets

The LabVIEW Simulation Interface Toolkit supports running a simulation on the following types of National Instruments RT Series Hardware:

  • PXI
    • Any PXI-RT controller
  • FieldPoint
    • Any Compact FieldPoint controller
  • CompactRIO
    • Any CompactRIO controller is supported. A default bitfile is provided for the cRIO-9103 with NI 9215, NI 9263, NI 9411 and NI 9474 I/O modules. If you are using a different controller or a different set of I/O modules, you can use LabVIEW FPGA module to compile a custom bitfile.
    • You can use the Single Point Timed I/O Timing Engine in the FPGA Wizard to help create the FPGA VI for use with SIT. FPGA VIs created by the FPGA Wizard can only be used when there is only one HW timed device in the system. If you are using more than one HW timed device (e.g. two R-series boards in a PXI chassis) you need to use the template provided with SIT.
    • If you are using a VxWorks-based controller refer to theX:\SimulationInterfaceToolkit\2011\VxWorks\readme_sit_vxworks.txtfile for information about enabling VxWorks support, where X is the drive where you installed the Simulation Interface Toolkit.
    • National Instruments recommends that you do not install the Scan Engine if you are using the CompactRIO controller with Simulation Interface Toolkit.

The LabVIEW 2012 Simulation Interface Toolkit ships with FPGA VIs for the following FPGA devices:

  • NI PCI-7811R

Development Tips

  • Driver VIs running on NI FPGA devices use the hardware settings for channel measurements.
  • In order to use the example .mdl files, that are included with SIT, when the execution host is set to driver VI on local or real-time, you first must compile the model into a DLL using Simulink®.

Known Issues

You can access the software and documentation known issues list online. Refer to the National Instruments Web site for an up-to-date list of known issues in the LabVIEW Simulation Interface Toolkit.


You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes. However, starting with the August 2012 releases (products using NI Installers version 3.1 or later), you may need to perform additional steps before or during a silent installation of NI software.

If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.
