The NI cRIO-9057 is a rugged 8-slot CompactRIO embedded controller designed for distributed measurement, industrial automation, machine monitoring, and deterministic real-time control. It combines an Intel Atom dual-core processor, Artix-7 100T FPGA, NI Linux Real-Time, modular C Series I/O, and TSN synchronization into one industrial platform.
Typical applications include:
- Distributed data acquisition
- Industrial automation
- Machine condition monitoring
- Remote measurement systems
- Embedded test systems
- Industrial IoT edge nodes
- Energy monitoring
- Synchronized industrial control
Processor and FPGA Architecture
The cRIO-9057 is built around:
- Intel Atom E3805 dual-core processor
- 1.33 GHz CPU frequency
- 2 GB DRAM
- 4 GB onboard storage
- Xilinx Artix-7 100T FPGA
- 8-slot CompactRIO architecture
- NI Linux Real-Time OS
The Artix-7 100T FPGA provides hardware-level timing, deterministic trigger logic, digital processing, encoder handling, and custom FPGA control logic. NI lists the FPGA resources as 126,800 flip-flops, 63,400 6-input LUTs, 240 DSP slices, 4,860 kbits block RAM, 16 DMA channels, and 32 logical interrupts.
TSN and Synchronization
The cRIO-9057 supports TSN deterministic communication synchronization, making it suitable for multi-node measurement and control systems.
This is useful for:
- Multi-controller synchronization
- Distributed machine monitoring
- Remote data acquisition
- Industrial Ethernet automation
- Synchronized test systems
- Energy and facility monitoring
Compared with older CompactRIO controllers, the cRIO-9057 is better suited for distributed systems that require network-based timing coordination.
Modular C Series Expansion
The cRIO-9057 supports up to 8 NI C Series modules, allowing engineers to configure the system around specific signal and control requirements.
Common module types include:
- Analog input/output
- Digital I/O

The cRIO-9057 supports hardware-timed analog and digital tasks through NI-DAQmx and LabVIEW workflows. In NI-DAQmx mode, analog input timing resolution is listed as 12.5 ns, timing accuracy as 50 ppm, and the maximum sample rate depends on the installed C Series modules.
This makes the controller suitable for:
- Synchronized sensor acquisition
- Deterministic digital triggering
- Embedded measurement systems
- Machine monitoring
- Test stand automation
Connectivity and Industrial Design
The cRIO-9057 provides:
- 2 Ethernet controller ports

Application-Oriented Use Cases
Machine Condition Monitoring
With vibration, IEPE, temperature, and analog input modules, the cRIO-9057 can be used for equipment health monitoring, bearing diagnostics, rotating machinery analysis, and predictive maintenance systems.
Distributed Measurement
Its TSN support and Ethernet connectivity make it useful as a synchronized remote acquisition node in factories, energy systems, laboratories, and large test facilities.
Industrial Automation
The controller can run deterministic control tasks through NI Linux Real-Time while using FPGA resources for low-latency timing, triggering, and custom digital control.
Embedded Test Systems
The cRIO-9057 is suitable for test stands that require mixed analog measurement, digital control, sensor acquisition, and real-time execution in one rugged embedded controller.
