Working Principle
The NI CRI0-9073 operates as the central controller in a CompactRIO system. The real-time processor runs a deterministic operating system (such as NI Linux Real-Time) and executes the user’s control application, handling tasks such as data logging, communication, and high-level decision-making. Simultaneously, the reconfigurable FPGA implements custom hardware-level logic for precise timing, triggering, and signal processing. The FPGA directly interfaces with C Series I/O modules, performing high-speed acquisition and generation with microsecond-level determinism. Processed data is transferred between the FPGA and the real-time processor via a high-speed internal bus. The system communicates with host computers, HMIs, or other controllers via Ethernet, serial, or fieldbus interfaces. Users develop applications using NI LabVIEW or other supported programming environments, deploying the real-time code to the processor and the FPGA bitstream to the FPGA. The hot-swappable I/O architecture allows modules to be added, removed, or replaced without powering down the controller, minimizing system downtime.
Installation Requirements
Mount the controller securely on a DIN rail or panel using the provided mounting hardware
Ensure adequate ventilation around the controller for heat dissipation
Connect the power supply (9-30V DC) using proper gauge wiring and secure terminals
Insert compatible C Series I/O modules into the available slots, ensuring proper seating
Connect Ethernet and serial communication cables using shielded industrial-grade cables
Configure the controller’s network settings (IP address, subnet) for communication with host systems
Install NI software (LabVIEW, CompactRIO drivers) on the development computer
Deploy the application code and FPGA bitstream from the development environment to the controller
Verify I/O module recognition and configuration in the NI MAX software
Usage Precautions
Ensure the power supply voltage is within the 9-30V DC range to prevent damage
Do not remove I/O modules while the system is actively acquiring or generating signals unless hot-swap procedures are followed
Monitor the controller’s operating temperature and ensure adequate ventilation
Back up application code and FPGA configurations regularly
Verify firmware and driver version compatibility between the controller and development software
Use proper grounding practices to minimize electrical noise and ensure signal integrity
Do not exceed the specified environmental limits for temperature, humidity, and vibration
Refer to NI documentation for troubleshooting error codes and diagnostic messages
Keep the controller firmware and I/O module firmware up to date
Handle the controller and I/O modules with care to avoid electrostatic discharge damage
