cRIO-9068

The NI cRIO-9068 is a rugged 8-slot CompactRIO embedded controller designed for industrial automation, distributed measurement, machine monitoring, and deterministic real-time control in harsh environments. It combines a dual-core ARM Cortex-A9 processor, Xilinx Zynq-7020 FPGA, modular C Series I/O, and NI Linux Real-Time into a compact embedded control platform.

Typical applications include:

• Industrial automation
• Distributed data acquisition
• Machine condition monitoring
• Remote measurement systems
• Embedded test systems
• Energy monitoring
• Outdoor industrial control
• Harsh-environment deployment

Processor and FPGA Architecture

The cRIO-9068 is based on a Zynq SoC architecture, integrating ARM processing and FPGA hardware in one platform.

Key architecture features include:

• 667 MHz dual-core ARM Cortex-A9 processor
• Xilinx Zynq-7020 FPGA
• 8-slot CompactRIO architecture
• NI Linux Real-Time operating system
• Modular NI C Series I/O support

The FPGA layer supports deterministic timing, trigger logic, encoder handling, digital processing, custom FPGA control, and real-time signal processing. This makes the cRIO-9068 suitable for systems where software-only control is not stable enough for timing-critical industrial tasks.

Modular C Series Expansion

The cRIO-9068 supports up to 8 NI C Series modules, allowing engineers to configure the system for mixed signal and industrial control requirements.

Common module types include:

• Analog input/output
• Digital I/O
• Temperature measurement
• Strain and bridge measurement
• Vibration and IEPE acquisition
• CAN communication
• Serial communication
• Industrial communication interfaces

The 8-slot architecture makes it suitable for systems requiring more sensor channels, more I/O diversity, or distributed monitoring across multiple physical processes.

Rugged Industrial Design

The cRIO-9068 is positioned for more demanding environments than standard cRIO-906x controllers. It is suitable for industrial cabinets, outdoor systems, transportation platforms, energy infrastructure, and remote monitoring stations.

Industrial design advantages include:

• Rugged fanless construction
• Wide-temperature deployment suitability
• Compact 8-slot embedded design
• DIN-rail and panel mounting support
• Industrial power input
• Shock and vibration resistance

For engineers, the main value of cRIO-9068 is stable long-term operation in environments where standard controllers may not be reliable enough.

Application-Oriented Use Cases

Machine Condition Monitoring

With vibration, temperature, and analog input modules, the cRIO-9068 can be used for motor monitoring, pump diagnostics, bearing analysis, and predictive maintenance.

Remote Industrial Measurement

The rugged 8-slot design is suitable for remote data acquisition nodes in energy systems, factories, transportation systems, and outdoor industrial monitoring.

Embedded Industrial Automation

The controller can run real-time control logic through NI Linux Real-Time while using FPGA resources for low-latency triggering, digital timing, and custom signal handling.

Embedded Test Systems

The cRIO-9068 is suitable for test platforms requiring mixed-signal acquisition, serial communication, digital control, rugged deployment, and deterministic execution.

Comparison with Similar Models

Compared with cRIO-9067, the cRIO-9068 is more suitable for harsh-environment deployment. Compared with newer cRIO-9057 systems, the cRIO-9068 uses an earlier Zynq architecture, but it remains practical for rugged distributed acquisition and embedded control applications.

Conclusion

The NI cRIO-9068 is a rugged 8-slot CompactRIO controller for harsh-environment industrial automation, distributed measurement, embedded monitoring, and deterministic control.

Its combination of:

• ARM Cortex-A9 processing
• Xilinx Zynq FPGA
• NI Linux Real-Time
• 8-slot C Series expansion
• Rugged industrial construction
• FPGA-based deterministic timing

makes it a practical choice for engineers building remote monitoring systems, machine condition monitoring platforms, embedded test systems, and distributed industrial control nodes.
