Supported Hardware and Software

Refer to KB 6CCA8MEG, Supported Hardware and Software for NI-Industrial Communications for DeviceNet, for a complete list of NI hardware and software supported by each version of the NI-Industrial Communications for DeviceNet.

The maximum number of devices you can connect to a DeviceNet interface depends on the electrical characteristics of the devices on the network. If all of the devices on the network meet the DeviceNet specifications, you may connect 64 devices to the network.

Caution  The NI-Industrial Communications for DeviceNet software does not support the previous generation of the DeviceNet hardware products such as NI PCI-DNET, NI PCMCIA-DNET, and NI PXI-8461/D. Those products require an NI-DNET 1.x driver.

Installation Instructions

Download the NI-Industrial Communications for DeviceNet installer from NI software includes NI Package Manager to handle the installation. Refer to the NI Package Manager Manual for more information about installing, removing, and upgrading NI software using NI Package Manager.

Accessing the Help

Refer to the NI-Industrial Communications for DeviceNet Help, accessible by selecting Help»NI-Industrial Communications for DeviceNet in LabVIEW, for information about using the NI-Industrial Communications for DeviceNet software.

Finding Examples

Select Help»Find Examples from LabVIEW to launch the NI Example Finder. LabVIEW examples for the NI-Industrial Communications for DeviceNet software are in the labview\examples\NI-Industrial Communications for DeviceNet folder. 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.

Compatibility with NI-DNET 1.x

NI-Industrial Communications for DeviceNet 2.1 or later is not an update for NI-DNET 1.x and the two products can be installed on the same system side by side. DeviceNet 2.1 or later provides NI-DNET 1.x compatible VIs, so the application using NI-DNET 1.x VIs can work with DeviceNet 2.1 or later on PCI-8532, PXI-8532 and NI 9882 with very limited code change.

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
