NI expansion I/O chassis decouple the controller in the reconfigurable I/O (RIO) system from the field-programmable gate array (FPGA) and I/O. Each chassis implements a different communication bus between the FPGA and the controller to suit different application needs. Expansion I/O chassis are equipped with the ability to connect multiple chassis to a single controller, scaling the benefits of the C Series platform to RIO applications requiring hundreds or even thousands of channels. Featuring more than 100 NI and third-party modules, the C Series platform provides integrated signal conditioning and direct sensor connectivity, making the chassis an efficient solution for large mixed I/O systems and eliminating the need for external custom circuitry and wiring. Each expansion I/O chassis also contains a Xilinx FPGA that is programmable with the NI LabVIEW FPGA Module, giving you control over high-speed and customizable I/O timing, inline processing, and closed-loop control.
MXI-Express RIO chassis connect the controller and FPGA through a high-throughput x1 cabled PCI-Express connection. This high-performance bus allows theoretical data rates up to 250 MB/s, making MXI-Express RIO chassis ideal for applications that require high-channel counts and high bandwidth such as hardware-in-the-loop (HIL) testing, industrial machine condition monitoring, sound and vibration, and complex research applications.
EtherCAT RIO chassis connect the FPGA to a real-time master controller through EtherCAT, a deterministic Ethernet-based communication protocol. With EtherCAT RIO chassis, you can distribute your industrial I/O across your entire application area and synchronize all of your I/O to a single host controller.
Using Ethernet RIO chassis, you can add FPGA-powered I/O to any Ethernet network. Flexible Ethernet connectivity helps you add industrial, signal-conditioned I/O to any CompactRIO controller, PXI controller, industrial controller, or Windows PC on the network.
