OverviewUse the LabVIEW Model Interface Toolkit to connect simulation models from a variety of simulation environments and programming languages to real-world I/O.
System RequirementsThe LabVIEW 2020 Model Interface Toolkit requires the LabVIEW 2020 Full or Professional Development System (32-bit) and any system requirements for LabVIEW 2020. Refer to the LabVIEW Readme for additional system requirements and supported operating systems for LabVIEW 2020.
To integrate and run your existing compiled models, you need only the Model Interface Toolkit installed. However, to perform other tasks with models you need additional software, as the following list describes:
To develop a model using MathWorks Simulink® application software, you must be a licensed user of and have the following software installed on the host computer:
To compile a model developed using MathWorks Simulink software, you must be a licensed user of and have the following software installed on the host computer:
MathWorks Real-Time Workshop® (Simulink Coder®).
VeriStand Model Framework. You must complete step 3 of the Installation Instructions section to install the VeriStand Model Framework item on the feature selection screen of the VeriStand installer. Refer to the NI website for a list of compilers that are tested and supported.
To compile a LabVIEW VI into a .lvmodel or .lvmodelso file you can load and run, you must complete step 3 of the Installation Instructions to install the VeriStand LabVIEW Model Support item on the feature selection screen of the VeriStand installer.
If you use other modeling environments, contact your model vendor for requirements for developing a model and converting it into a compiled model.
Supported Operating SystemsThe LabVIEW Model Interface Toolkit supports the following operating systems:
Note In 2016, the LabVIEW Model Interface Toolkit dropped support for Windows Vista, Windows XP, Windows Server 2003, and installations of Windows 7 without any service packs. The LabVIEW 2020 Model Interface Toolkit will not install or run on an unsupported OS. You cannot deploy or distribute applications that use the LabVIEW 2020 Model Interface Toolkit to an unsupported OS. Additionally, after installing the LabVIEW 2020 Model Interface Toolkit, you cannot use any installers built on this computer with any version of LabVIEW, LabWindows™/CVI™, NI TestStand™, or Measurement Studio on an unsupported OS.
For more information about the changes to our OS support for 2020, refer to KB 79UC78LS, Why Does my LabVIEW, LabWindows/CVI, Measurement Studio, or TestStand Built Installer Fail on Windows XP/Vista and Server 2003?.
Note Support for Windows 32-bit operating systems may require disabling physical address extension (PAE). To learn how this might affect your system and what actions you might need to take, visit ni.com/info and enter the Info Code PAESupport.
1 NI software installs VC2015 Runtime and .NET 4.6.2. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.
2 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
Application Software SupportThe Model Interface Toolkit 2020 supports the following application software versions, including service packs.
Application Software | Versions Supported by Model Interface Toolkit |
| LabVIEW Full or Professional Development System (32-bit) | 2020 |
Installation InstructionsUse NI Package Manager or NI Software Product Downloads to install the LabVIEW 2020 Model Interface Toolkit.

Upgrade and Compatibility IssuesThe VeriStand Model Framework contains changes to the files you use to develop and compile models in C/C++ and third-party modeling environments. If your system contains models compiled with previous versions of the Model Framework, choose from the following options for continuing to use the models in VeriStand 2020:
If you do not need to update your model or deploy it to Intel x64-based targets that run NI Linux Real-Time, you can continue to use the model as-is.
If you need to update functionality of your model that does not require the changes in the latest version of the Model Framework, you can recompile the model against the deprecated Model Framework files. These files are installed at <RootDrive>VeriStand ersionModelInterfacecustomsrcobsolete. However, you cannot deploy the recompiled model to Intel x64-based targets that run NI Linux Real-Time.
To use the new features in the latest version of the Model Framework, or if you need to deploy the model to Intel x64-based targets that run NI Linux Real-Time, update and recompile the models using the 2020 version of the Model Framework. Update your models according to the following differences between new files in the Model Framework and the deprecated files they replace:
This file is installed on disk at <custom>src
i_modelframework.c rather than in the <custom> directory.
USER_TakeOneStep() now returns an int32_t value rather than void. If the function completes successfully, it returns NI_OK. If an error occurs, this function returns NI_ERROR.
The USER_ModelName global variable is a const char and replaces the ModelName variable.
The USER_Builder global variable is a const char and replaces the build variable.
The USER_BaseRate global variable is a const char and replaces the baserate variable.
Implements fixed-width data types from the C99 standard, such as replacing int with int32_t where applicable.
Replaces use of the long data type with int32_t or uint32_t where applicable to achieve cross-platform compatibility.
ni_modelframework.h contains the following differences from NIVERISTAND_API.h:
ni_modelframework.c contains the following differences from codegen.c:
Known IssuesYou can access the software and documentation known issues list online. Refer to the NI website for an up-to-date list of known issues in the LabVIEW 2020 Model Interface Toolkit.
Bug FixesFor a complete list of the IDs and titles of the issues fixed in this release, see LabVIEW Model Interface Toolkit 2020 Bug Fixes. If you have a Bug or Legacy ID, you can search the list to validate that the issue has been fixed.
Accessing the Software and HelpTo access the Model Interface Toolkit VIs, select View»Functions Palette from the block diagram in LabVIEW and navigate to the Control Design & Simulation»Model Interface palette. You also can right-click any blank space on the block diagram to display the Functions palette.
Refer to the Toolkits»Model Interface Toolkit book on the Contents tab of the LabVIEW Help for more information about the Model Interface Toolkit.
Finding ExamplesSelect Help»Find Examples from LabVIEW to launch the NI Example Finder. LabVIEW examples for the Model Interface Toolkit are located in the labviewexamplesControl and SimulationModel Interface directory. You can modify an example VI to fit an application, or you can copy and paste from one or more examples into a VI that you create.
The example models included with the Model Framework are located at <RootDrive>VeriStand ersionModelInterfacecustomexamples.
Automating the Installation of NI ProductsYou 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.
For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:
For more information about silent installations of individual NI products, refer to KB 4CJDP38M, Automating the Installation of a Single Installer.
For more information about silent installations of NI products in a suite, such as NI Developer Suite, refer to KB 4GGGDQH0, How Do I Automate the Installation of a Suited Installer?.
To determine what version of NI Installers your product contains, refer to KB 4CJDR18M, How Can I Determine the Type and Version of My NI Installer?.
Using NI Software with Microsoft Windows 10Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions. Windows 10 introduces several new capabilities and also combines features from both Windows 7 and Windows 8. For more information about NI support for Windows 10, visit ni.com/windows10.
