1-Port, Low-Speed/Fault Tolerant C Series CAN Interface Module—The NI‑9861 is a fault-tolerant Controller Area Network (CAN) interface for developing applications with the NI‑XNET driver. The NI‑9861 is ideal for applications requiring real-time, high-speed manipulation of hundreds of CAN frames and signals, such as hardware‑in‑the‑loop simulation, rapid control prototyping, bus monitoring, automation control, and more. You can perform this manipulation while taking other data acquisition measurements in the same NI CompactDAQ hardware platform or while performing low-level FPGA control and embedded monitoring in the same NI CompactRIO chassis.
