What is CompactRIO?

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.


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.


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.

Combined DAQ & 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


CompactRIO System 

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.




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.



The CompactRIO real-time controller is a high-performance integrated controller that features extreme ruggedness, 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 communication with peripherals.

CompactRIO Modules


I/O modules contain isolation, conversion circuitry, signal conditioning, and built-in connectivity for direct connection to industrial sensors/actuators. By offering a variety of wiring options and integrating the connector junction box into the modules, the CompactRIO system significantly reduces space requirements and field-wiring costs. You can choose from more than 70 NI C Series I/O modules for CompactRIO to connect to almost any sensor or actuator.



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.
