Legal Information


The LabVIEW Real-Time Module is a complete solution for creating reliable, stand-alone embedded systems with a graphical programming approach. As an add-on to the LabVIEW development environment, the LabVIEW Real-Time Module helps you develop and debug graphical, deterministic real-time applications that can be downloaded to and executed on embedded hardware devices such as NI CompactRIO, NI CompactDAQ, NI Single-Board RIO, PXI, vision systems, or even third-party PCs.

System Requirements

  • LabVIEW 2015 SP1 Full or Professional Development System (32-bit)
  • At least 200 MB of disk space in addition to the LabVIEW-recommended minimum
  • One of the following operating systems for application development:
    • Windows 10
    • Windows 8.1
    • Windows 7 Service Pack 1
    • Windows Vista
    • Windows XP Service Pack 3 Professional
    • Windows Server 2003 R2 (32-bit)
    • Windows Server 2008 R2 (64-bit)

Refer to the LabVIEW Readme for additional system requirements and supported operating systems for LabVIEW 2015 SP1.


  • The Real-Time Module is compatible with LabVIEW (32-bit) only. Therefore, you must have LabVIEW (32-bit) installed even if you use a 64-bit OS.
  • You might need more memory than the LabVIEW-recommended minimum depending on the size of the application you design in LabVIEW on the host computer.
  • Support for Windows Server 2003 R2 might require disabling physical address extensions (PAE). Refer to the NI website for information about how this might affect your use of Windows Server 2003 R2 and what actions you might have to take.
  • The Real-Time Module does not support the Windows Server non-R2 editions.

The Real-Time Module installs the following real-time operating systems (RTOSes). Refer to the specific RT target hardware documentation for information about which RTOS your target uses.

  • NI ETS
  • NI Linux Real-Time
  • VxWorks

Note:  Each RTOS supports only a subset of LabVIEW features. Refer to the Real-Time Module»Real-Time Operating Systems book on the Contents tab of the LabVIEW Help for a list of unsupported LabVIEW features and special considerations for each RTOS.

Application Software Support

The following table lists the application software versions, including service packs, supported by the LabVIEW 2015 SP1 Real-Time Module.

Application Software Versions Supported by Product
LabVIEW 2015 SP1 (32-bit only)

Installation Instructions

You can install all of your LabVIEW products—including the Real-Time Module—using the LabVIEW 2015 SP1 Platform media. Refer to the LabVIEW Installation Guide on the LabVIEW Platform media for installation instructions and system requirements.

To request additional LabVIEW Platform media, refer to the NI website.

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.

Installing and Using Japanese and Simplified Chinese Languages on an RT Target

After you install the Real-Time Module on your development computer, you can complete the following steps to install and use Japanese and Simplified Chinese languages on an RT target:

  1. Use the LabVIEW Real-Time Software Wizard in NI Measurement & Automation Explorer (NI MAX) to install the Language Support for Japanese or Language Support for Simplified Chinese software component on the RT target. Refer to the Measurement & Automation Explorer Help for information about the LabVIEW Real-Time Software Wizard.
  2. Open the System Settings tab and select Japanese or Simplified Chinese as the Locale.

Note:  You cannot use Japanese or Simplified Chinese characters in directory names or filenames on the RT target.

Known Issues

You 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 Real-Time Module.

Bug Fixes

The following items are the IDs and titles of a subset of issues fixed in the Real-Time Module. This is not an exhaustive list of issues fixed in the current version of the Real-Time Module. If you have a CAR ID, you can search this list to validate the issue has been fixed.

ID Fixed Issue
537230 Modifications to a VI with dynamic references break the VI with error -1055 at any Property Node.
539908 The Two Button Dialog function does not wait for user input and always returns False from the T button? output.

Accessing the Help

Refer to the LabVIEW Help, accessible by selecting Help»LabVIEW Help from LabVIEW, for information about the Real-Time Module.

Finding Examples

Select Help»Find Examples from LabVIEW to launch the NI Example Finder. LabVIEW examples for the Real-Time Module are located in the labview\examples\Real-Time Module 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.

Automating the Installation of NI Products

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.

For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:

Using NI Software with Microsoft Windows 10

Microsoft 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

Using NI Software with Microsoft Windows 8.1

When you install NI software on Microsoft Windows 8.1, you will notice a few additional tiles in the Apps view, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (NI MAX), and NI Launcher.

Using NI Launcher

NI Launcher helps you find and launch installed NI products. It provides you with a method of finding NI products similar to the Start menu in previous versions of Microsoft Windows. To use NI Launcher, click the NI Launcher tile in the Apps view. NI Launcher launches the desktop and opens a menu containing a list of NI products. Click any NI product to launch it.

Note  NI MAX does not appear as a desktop shortcut when installed on Microsoft Windows 8.1. You can launch NI MAX either from the Apps view or from within NI Launcher.

Pinning Frequently Used Applications

For convenience, you can pin your most-used NI applications, such as MAX, to either the Start screen or the Taskbar on the desktop, as necessary:

Current ApplicationIcon LocationPin to Action
Windows 8.1 DesktopDesktop TaskbarRight-click application and select Pin to Taskbar
Windows 8.1 Desktop Start screenRight-click application and select Pin to Start
Windows 8.1 Start screenDesktop TaskbarRight-click application and select Pin to taskbar from the menu bar on the bottom of the screen

Finding All Programs

If you want to find a particular application or related files, such as documentation files, from the Start screen, you can access all installed files from the Apps view. To get to the Apps view, click the down arrow on the bottom left of the screen.
