Solution
The onboard CAN port of sbRIO-9606/9607, sbRIO-9626/9627/9633/9636, sbRIO-9651 System on Module (SOM), and roboRIO are not compatible with the NI-XNET or NI-CAN drivers.
Instead, they use the NI-Embedded CAN for RIO driver , which can be considered to be a condensed version of the NI-XNET or NI-CAN driver.
The NI-Embedded CAN for RIO driver is similar to the Frame API of the NI-XNET driver. With this driver you may open, configure, and close the CAN port, as well as read/write frames. There are no advanced features, such as databases, clusters, signals, channels, etc.
The palette for NI-Embedded CAN for RIO driver is shown below:
The palette can be found by right-clicking on the block diagram of a LabVIEW Real-Time VI to open the Functions Palette » Industrial Communications » Embedded CAN for RIO.
Shipping examples can be found at <LabVIEW>\examples\NI-Embedded CAN for RIO.
