1‑ or 2-Port, Low-Speed/Fault Tolerant PXI CAN Interface Module—The PXI‑8511 is a fault-tolerant Controller Area Network (CAN) interface for developing applications with the NI‑XNET driver. The PXI‑8511 excels in 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. The NI‑XNET device-driven DMA engine enables the onboard processor to move CAN frames and signals between the interface and the user program without CPU interrupts, minimize message latency and freeing host processor time for processing complex models and applications.
