What is CompactRIO?

develop your compactrio system faster using the labview fpga module, the daq mx driver, and ni linux real-time

CompactRIO systems provide high-performance processing capabilities, sensor-specific conditioned I/O, and a closely integrated software toolchain that make them ideal for Industrial Internet of Things, monitoring, and control applications. The real-time processor offers reliable, predictable behavior, while the FPGA excels at smaller tasks that require high-speed logic and precise timing.

Flexible Development Options

Abstract low-level code and use a single toolchain to build and deploy time-critical applications on your CompactRIO system using LabVIEW and the real-time and FPGA modules.


Long-Term Data Acquisition

Utilize the integrated controller running a Linux Real-Time OS and sensor-specific I/O modules to build and deploy robust applications directly on the CompactRIO controller.


Combined DAQ and Control

Take advantage of the user-programmable FPGA and integrate existing intellectual property (IP) when you need to acquire high-quality data and process and respond to it in real time.


Open, Secure Platform

Harness the openness of the NI Linux Real-Time OS through thousands of open-source applications, IP, and examples, while collaborating with an active community of users and developers.

Why Choose CompactRIO?

CompactRIO hardware provides an industrial control and monitoring solution using sensor- or protocol-specific, conditioned I/O modules with real-time capabilities.

Best for

  • Real-time processing needs

  • Industrial monitoring and control applications 

  • Long-term testing in the field

a compactrio system contains a chassis, controller, and interchangeable input and output modules

CompactRIO System Components

CompactRIO systems feature a controller with a processor running a Linux Real-Time OS and a chassis that contains a user-programmable FPGA. It supports industrial I/O modules from both NI and third-party vendors.







8 slot and 4 slot compactrio chassis

The CompactRIO chassis is the center of the integrated system architecture. It is directly connected to the I/O for high-performance access to the I/O circuitry of each module and timing, triggering, and synchronization. Because each module is connected directly to the FPGA rather than through a bus, you experience almost no control latency for system response compared to other controller architectures.


compactrio real-time controllers are rugged, featuring integrated vision and industrial communication

The CompactRIO Controller is a high-performance controller that features rugged design, industry-standard certifications, integrated vision and motion, industrial communication, and human-machine interface capabilities. It contains a processor that reliably and deterministically executes LabVIEW Real-Time applications and offers multirate control, execution tracing, onboard data logging, and peripheral communication. The CompactRIO Controller comes integrated with a CompactRIO Chassis.

Overcome traditional heterogeneous architecture programming challenges with NI Linux Real-Time, the LabVIEW FPGA Module, and the NI-DAQmx driver. With this combination, you can develop your system faster by programming both the processor and user-programmable FPGA with a single, intuitive software toolchain. Focus on solving problems, not low-level programming tasks, with integrated user-friendly software that reduces risk, enhances productivity, and eliminates the need to create and maintain I/O drivers, OSs, and other middleware.
