NI-CAN supports the following Microsoft Visual Studio versions and associated programming languages.


Programming Languages Versions Supported by NI-CAN 18.5
Microsoft Visual C/C++ 6.0 and later
Microsoft Visual Basic 6.0 and later

Note  NI-CAN also supports Borland C/C++.


Installation Instructions

Before installing the NI-CAN software, log on as Administrator or as a user with Administrator privileges. The NI-CAN software setup program must have Administrator privileges because the program modifies the configuration registry of your system. Complete the following steps to install the NI-CAN software.


  1. Insert the NI-CAN software CD into your CD-ROM drive. The installer launches if your CD-ROM drive plays data CDs automatically. If the installer does not launch automatically, navigate to the CD using Windows Explorer and launch the autorun.exe file from your NI-CAN software CD.
  2. The installation wizard guides you through the necessary steps to install the NI-CAN software. You can go back and change values where appropriate by clicking the Back button. You can exit the setup where appropriate by clicking Cancel.
  3. When the installation is complete, click Finish.


Beginning with version 18.5.0, NI-CAN installs support for the latest version of LabVIEW found on the system. If you require support for more than one version of LabVIEW, complete the following steps:


  1. Install NI-CAN 18.5.0 or later.
  2. Restart the system.
  3. Copy the following folders from the latest version of LabVIEW to the folder of the older version of LabVIEW. [LVDIR] indicates the folder of the latest LabVIEW version.
    • [LVDIR]\vi.lib\nican
    • [LVDIR]\examples\nican
    • [LVDIR]\help\nicanhelp.chm
    • [LVDIR]\help\nicanhelp.txt
    • [LVDIR]\menus\Categories\Measurement\_NICAN
    • [LVDIR]\menus\Categories\Measurement\can.mnu

You should now be able to use NI-CAN with both versions of LabVIEW.


The NI-CAN API is mass-compiled in LabVIEW 2015. This will not affect the functionality of your VIs. However, LabVIEW will prompt you to save the NI-CAN subVIs for LabVIEW 2015 and later. To avoid the prompts, mass compile the folders referenced above. If you require NI-CAN support for earlier versions of LabVIEW, you need an earlier version of NI-CAN.


Note  Installers for NI-CAN 18.5.0 and later remove NI-CAN support for previous versions of LabVIEW. When you install NI-CAN 18.5.0 or later to upgrade an existing NI-CAN installation, NI-CAN support will be available only in the latest version of LabVIEW installed on your system. To restore support for other LabVIEW versions, complete the steps above. It is important to copy the support files to all versions of LabVIEW immediately after the NI-CAN installation is complete.

Additional Programming Topics

NI-DAQ Synchronization VIs

Traditional NI-DAQ driver software is not supported on Windows Vista or Windows 7; therefore, the following CAN/DAQ synchronization VIs are not available on Windows Vista or Windows 7:


  • CAN Clear with NI-DAQ.vi
  • CAN Clear Multiple with NI-DAQ.vi
  • CAN Sync Start with NI-DAQ.vi
  • CAN Sync Start Multiple with NI-DAQ.vi

Support of CANdb (*.DBC) Files

NI-CAN provides support for CANdb network files created using the Vector CANdb or CANdb++ editor. You can use the information from the CANdb file in Measurement & Automation Explorer (MAX) or with the NI-CAN Channel API. For more information, refer to "Using the Channel API" in the NI-CAN Help.


NI-CAN supports CANdb network files created using the CAN module of Vector products. NI-CAN does not provide complete support of CANdb files created using modules for higher-layer CAN protocols, such as J1939, ISO11783, or NMEA2000. To view the set of features supported for these modules, import the CANdb file into MAX. NI-CAN displays an error dialog for any unsupported object and displays those objects with a red mark. For example, the J1939 protocol for multiframe messages (greater than 8 bytes) is not supported in the current version of NI-CAN.


Updating Get/Set Attribute in Frame API for LabVIEW

NI-CAN 2.4 (or newer) includes several new Frame API attributes. If you have a LabVIEW VI written for an earlier version of NI-CAN, upgrading to NI-CAN 2.4 (or newer) will not automatically update constants or controls for the AttrId input. To use the new attributes, replace your older constants and controls using the AttrId input of the updated NI-CAN VIs.


If you do not want to use new Frame API attributes, you can continue to use the older constants and controls for compatibility.


This issue does not apply to the Channel API for LabVIEW. Because the Get/Set Property functions are provided as polymorphic VIs, they are automatically updated.


Release Notes

  • The NI-XNET Compatibility Layer for NI-CAN currently supports the following hardware:
    • PCI-8511, PCI-8512, PCI-8513, PXI-8511, PXI-8512, and PXI-8513 (Windows and Phar Lap)
    • NI 9861 and NI 9862 (Windows only) (In LabVIEW, these models appear as PCI-8511 and PCI-8512 1-port variants.)
    • USB-8501, USB-8502, and USB-8506 (Windows only, Frame API only)
  • The NI-XNET Compatibility Layer for NI-CAN currently does not support the LabVIEW example Channel Monitor.vi.
  • For USB-LIN interfaces, the LIN bus must be terminated. This is typically done at the master node. For information about how to enable or disable termination on the USB-LIN, refer to the ncSetAttribute attribute function with the Frame API.
  • USB-LIN interfaces require external power from 8–18 V. For more details on power requirements, refer to hardware specifications, which are available on ni.com.
  • When hardware is first detected, the USB LED quickly switches between green and amber.
  • Fatal errors can cause the USB LED to flash in an error code pattern. Count the number of long and short flashes, then contact National Instruments support.
  • If you use a USB hub with USB CAN or LIN products, the hub must be powered.
  • Due to the inherent latencies of USB, the driver on the host side might process data or states that NI USB-847x series devices receive later than data from a plug-in (e.g., PCI, PXI, or PCMCIA) interface. This does not affect timestamps, as timestamps are generated on the hardware, but with NI USB-847x series devices it can cause timeout failures that do not happen on plug-in hardware. To avoid such timeout failures, increase the timeout value for functions that perform a wait for a certain state.

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 4.0, 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 ni.com/windows10.


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 ni.com/windows8.
