Supported Platforms

The Real-Time Module supports the following operating systems for application development:

  • Windows 7
  • Windows Vista
  • Windows XP Pro (Service Pack 2 or 3)
  • Windows Server 2003 R2 (32-bit)
  • Windows Server 2008 R2 (64-bit)


  • The Real-Time Module is compatible with 32-bit LabVIEW only. Therefore, you must have 32-bit LabVIEW installed even if you use a 64-bit OS.
  • Support for Windows Server 2003 R2 may require disabling physical address extensions (PAE). Refer to the National Instruments Web site 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 13.1
  • VxWorks 6.3

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


You can install all of your LabVIEW products, including the LabVIEW Real-Time Module, using the LabVIEW 2011 SP1 Platform DVDs. You can find installation and activation instructions for the Real-Time Module in the following locations:

  • LabVIEW Real-Time Module Release and Upgrade Notes, which are available in your LabVIEW Real-Time Module software kit or online at
  • LabVIEW Release Notes, which are available in your LabVIEW software kit.
  • LabVIEW 2011 Service Pack 1 Platform DVDs Readme, which is available on the top-level of LabVIEW Platform DVD 1.

To request additional LabVIEW 2011 SP1 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.

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 to install the Language Support for Japanese or Language Support for Simplified Chinese software component on the RT target. Refer to the NI 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 file names on the RT target.

New Feature

The LabVIEW 2011 SP1 Real-Time Module includes the new OPC UA VIs. Use the VIs on the OPC UA, OPC UA Server, and OPC UA Client palettes to create a customized OPC UA server application or OPC UA client application and exchange data between OPC UA client and OPC UA server applications. The OPC UA VIs are located on the Data Communication palette.
