CompactRIO Controller and Expansion Chassis

The document lists multiple models of CompactRIO controllers, with the main differences being the processor, FPGA size, and number of slots. For example:

CRIO-904x series: Intel Atom dual core or quad core, 1.30-1.60 GHz, 4 or 8 slots.

CRIO-905x series: 1.33 GHz dual core Intel Atom, 4 slots.

NI-914x series: EtherCAT or Ethernet expansion case for distributed I/O, operating temperature range of -40 ° C to 70 ° C.

All controllers support NI Linux Real Time operating system and offer multiple international power cord options (USA, UK, Switzerland, Australia, Europe, Japan, India, Korea, China, Brazil, Taiwan, etc.).

Single Board RIO (sbRIO): Embedded Single Board Controller for OEM

SbRIO is designed specifically for high-capacity OEM embedded control and analysis applications, integrating real-time processors, FPGAs, and I/O on a compact single board. It is part of an accelerated custom design platform that can help customers quickly bring embedded control systems to market. SbRIO is based on the CompactRIO platform, thus inheriting FPGA performance, real-time determinism, and reliability, while having lower non repetitive engineering costs compared to fully customized hardware designs.

The document lists multiple sbRIO models, with the main differences as follows:

Model processor RAM FPGA onboard I/O expansion interface

SbRIO-9603 Intel 1.33 GHz Dual Core 1 GB XC7A75T Digital I/O 2 × C Series, 96 DIO

SbRIO-9609 Intel 1.91 GHz quad core 2 GB XC7A200T only digital I/O 2 × C series, 96 DIO

SbRIO-9628 Intel 1.33 GHz Dual Core 1 GB XC7A100T 16 AI, 4 AO, 110 DIO 2 × C Series

SbRIO-9629 Intel 1.91 GHz Dual Core 2 GB XC7A200T 16 AI, 4 AO, 110 DIO 2 × C Series

SbRIO-9638 Intel 1.33 GHz Dual Core 1 GB XC7A100T 16 AI, 4 AO, 110 DIO 2 × C Series

SbRIO-9651 667 MHz dual core ARM Cortex-A9 512 MB XC7Z020 without onboard I/O 160 DIO, PCIe, SATA

SbRIO supports interfaces such as Time Sensitive Network (TSN), Dual Ethernet, CAN FD, RS-232/485, USB 3.1, and DisplayPort. At the same time, we provide thermal management kits, junction boxes, cable trays, and other accessories for easy integration.

Developing RIO System with LabVIEW

LabVIEW is the core development environment of the NI RIO platform, which abstracts complex underlying tasks in embedded system programming, enabling the design of advanced measurement and control systems without the need for a large development team or extensive experience in hardware description languages.

Unified project management: The main processor VI and FPGA VI are located in the same LabVIEW project for easy development and debugging. FPGA VI and real-time VI can efficiently exchange data through DMA FIFO or Interrupt (IRQ).

Built in library: LabVIEW contains nearly 1000 built-in signal processing, analysis, control, and mathematical functions, accelerating the development of embedded measurement systems.

Remote system management: The built-in system management tool supports remote updates of hundreds of controllers or data transfer between different systems.

Open software interoperability: LabVIEW can call external C code and integrate with Python,. NET, etc., making it easy to reuse existing IPs.

Developing a CompactRIO system typically involves creating an FPGA VI in a LabVIEW project to implement high-speed I/O and timing logic, creating a real-time VI to implement the main control loop, network communication, and data recording, and then compiling and deploying it to the target hardware. The graphical programming approach of LabVIEW makes FPGA development intuitive, without the need to learn VHDL/Verilog.

Industrial connectivity and environmental adaptability

CompactRIO supports multiple industrial communication protocols and can serve as an IIoT gateway to translate between different protocols. The supported protocols include:

EtherNet/IP

Modbus (Serial and TCP)

OPC UA

RS-232 / RS-485

MQTT

EtherCAT

CAN bus

DNP3

For harsh environments, CompactRIO has extensive international safety certifications, hazardous location certifications, and environmental certifications. Its working temperature range is wide from -40 ° C to 70 ° C, with high levels of shock and vibration, redundant power input, suitable for scenarios such as oil and gas, factory automation, etc.
