NI-9144

8-Slot, Spartan-3 2M FPGA, EtherCAT CompactRIO Chassis—The NI‑9144 is a rugged EtherCAT slave chassis for adding deterministic, distributed I/O to any CompactRIO, PXI, or industrial controller with two Ethernet ports. You can program the chassis using Scan Mode for fast expansion of your real-time system or using the onboard FPGA for inline processing and high-speed I/O and control. You can daisy chain multiple NI‑9144 slave chassis from the master controller to expand time-critical applications to higher channel counts while maintaining hard determinism with minimal processor resources.
