Issue Details

How can I do CAN communication with NI CompactRIO Single‐Board Controller (sbRIO)? What driver do I need?

Solution

Depending on the model of the NI sbRIO you are using, there are three type of drivers that you would need:

NI-Embedded CAN for RIO: Some sbRIO comes with onboard CAN port and is supported by NI-Embedded CAN for RIO. NI-Embedded CAN for RIO does not support CAN FD. For more information about this driver, see the links below:
NI CompactRIO : NI sbRIO with NI-DAQmx has dedicated CAN port which supports CAN and CAN FD. It uses low-level FPGA IO nodes based on NI-985x API. This support is added in NI CompactRIO 20.5 for LabVIEW 2020. See CompactRIO Single-Board Controller with NI-DAQmx Hardware Manual page 1 for list of supported hardware and page 49 on connecting CAN networks.
NI-XNET: If you wish to use the NI-XNET Driver with the sbRIO platform, some sbRIO supports the driver with NI-986x C Series Modules when connected through a Mezzanine Card. See Using a CompactRIO Single-Board Controller (sbRIO) with C-Series Modules and What sbRIO Controllers are Compatible with NI-XNET?

Additional Information

If you are looking for an example or a starting point on using the dedicated CAN port for the NI sbRIO with NI DAQmx you can refer to the shipping example that can be found in LabVIEW Help> Find examples> Hardware Input and Output> CompactRIO> Chassis Specific> sbRIO with DAQmx.

Documentation about the APIs involved in the above example can be found at the following sections of the CAN Module Reference and Procedures (FPGA Interface) manual
