Additional Programming Topics

NI-CAN Compatibility

If you intend to use the NI-CAN API with NI-XNET hardware, refer to the NI-XNET Compatibility for NI-CAN appendix in the NI-CAN Hardware and Software Manual.

Deployed databases on LabVIEW Real-Time targets

When upgrading the NI-XNET software on your LabVIEW Real-Time target, you need to re-deploy your database files to that target using a host computer that runs the same version of NI-XNET as the target.

Removing and inserting C Series modules on CompactRIO targets during device communication is not supported

Inserting a module into or removing a module from a cRIO chassis that is actively communicating with an NI 986x module can cause application failures and possibly device damage. This does not apply to controllers which support the NI-DAQmx programming method, such as the cRIO-904x family.

RT Bus Monitor requires LabVIEW Real-Time

Installing software to a Real-Time target using the "Other" programming environment will not run the RT Bus Monitor. To use this utility, select a "LabVIEW" or "LabVIEW NXG" programming environment.

Behavior Changes

The following behavior has changed in NI-XNET 20.5.1 from NI-XNET 20.5:

  • The NI-XNET IP Stack service no longer starts automatically when NI-XNET is first installed.

LabVIEW NXG Support and Considerations

The following sections detail considerations for using LabVIEW NXG with NI-XNET 20.5.1.

LabVIEW NXG Operating Systems and System Requirements

Software support for LabVIEW NXG differs in the following ways:

  • System requirements—Only 64-bit (x64) processors are supported.
  • Operating system—Only 64-bit operating systems are supported. Refer to the Supported Operating Systems section for more information.

Additional documentation is available online at

LabVIEW NXG Examples

Launch LabVIEW and click the Learning tab.

LabVIEW lessons are located in the Lessons tab, and LabVIEW Examples are located in the Examples tab. Follow the instructions in the lessons and examples.

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.

If the NI product you are installing uses Microsoft .NET 4.6.2, 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 4.6.2 separately before you install NI software.

For more information about automating the installation of NI products, refer to Automating an Installer in the NI Package Manager manual.

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. For more information about NI support for Windows 8.1, visit
