CompactRIO (or cRIO) is a real-time embedded industrial controller made by National Instruments for industrial control systems. The CompactRIO is a combination of a real-time controller, reconfigurable IO Modules (RIO), FPGA module and an Ethernet expansion chassis.
The CompactRIO system is a combination of a real-time controller chassis, reconfigurable IO Modules (RIO), an FPGA module and an Ethernet expansion chassis. Third-party modules are also available, and are generally compatible with NI-produced chassis controllers.
CompactRIO real-time controllers include a microprocessor for implementing control algorithms, and support a wide range of clock frequencies. Controllers are only compatible with National Instruments C Series I/O Modules. I/O modules are hot swappable (can be connected/disconnected while the unit is powered up).
The FPGA Module may be used to implement high-performance data processing on reconfigurable fabric. Such data processing may be performed on data streaming in from connected I/O Modules. The module is powered by a Xilinx Virtex high-performance FPGA. The FPGA can be programmed separately and is connected to the real-time controller using an internal PCI bus.
The Ethernet chassis includes an Ethernet port (8P8C), which can connect the CompactRIO controller to a PC. The chassis is available in 4 slot and 8 slot varieties.
Third-party modules are manufactured for additional features, such as LCD or VGA displays. Newer, high-performance CompactRIO controllers also have built-in VGA graphics which can be connected to a monitor for observing operation.
