What is Single-Board RIO (sbRIO)?
Introduction
Single-Board RIO (sbRIO) is an embedded control and acquisition platform developed by National Instruments (NI). Designed for applications that require high performance, reliable operation, and customizable I/O, sbRIO offers a powerful combination of a real-time processor, FPGA, and analog/digital I/O, all within a compact and rugged single board. This paper explains the core components, capabilities, and common use cases of sbRIO, as well as why it’s an ideal choice for industrial control and monitoring applications.
Core Components of Single-Board RIO
Real-Time Processor
The sbRIO includes a real-time processor running a reliable operating system (NI Linux Real-Time), which provides deterministic performance for embedded applications. It allows developers to deploy and execute high-level code, manage I/O, and interface with external systems.
Field-Programmable Gate Array (FPGA)
A key differentiator of the sbRIO is its integrated FPGA, which offers high-speed processing for time-critical tasks. The FPGA can be custom-programmed using LabVIEW FPGA, enabling precise control over I/O timing, high-speed signal processing, and rapid prototyping for custom applications.
Analog and Digital I/O
The board integrates multiple analog and digital I/O channels, enabling direct connection to sensors, actuators, and other peripherals. The flexible I/O configuration simplifies the development process and minimizes the need for additional hardware.
Benefits of Using Single-Board RIO
Integrated Platform
By combining the real-time processor, FPGA, and I/O on a single board, sbRIO reduces system complexity, enabling faster deployment and lower development costs.
Customizable and Scalable
The reconfigurability of the FPGA and the flexible software environment (LabVIEW) allow sbRIO to be tailored to unique application requirements. The platform scales easily from prototyping to production.
Reliable and Rugged Design
sbRIO boards are built for harsh environments with a rugged design that supports extended temperature ranges, vibration, and shock. They are ideal for industrial and embedded applications in critical settings.
Common Applications
Industrial Control and Automation
sbRIO is often deployed in machinery control, process automation, and custom automation systems where reliable and deterministic control is essential.
Monitoring and Data Acquisition
With its real-time processing and customizable I/O, sbRIO excels in monitoring systems, providing high-speed data acquisition and real-time analytics.
Embedded Control Systems
The platform is widely used in robotics, medical devices, and smart infrastructure where embedded control, precise timing, and high reliability are required.
Software Development with LabVIEW
One of the key strengths of sbRIO is its tight integration with NI’s LabVIEW software. Developers can design, simulate, and deploy both real-time and FPGA-based applications in a single environment. LabVIEW’s graphical programming interface simplifies development and reduces time-to-market.
Comparison to Other RIO Solutions
Single-Board RIO is part of the broader RIO family from NI, including CompactRIO and FlexRIO. This section compares sbRIO with these platforms in terms of performance, form factor, and use cases.
Conclusion
Single-Board RIO is a versatile, powerful embedded platform designed for engineers and developers who need a flexible and reliable control system. With its integrated real-time processor, FPGA, and flexible I/O, sbRIO delivers a scalable solution for a wide range of applications, from rapid prototyping to full-scale production.
