cRIO-9041

Земля NI cRIO-9041 прочный Компактный встраиваемый контроллер CompactRIO с 4 слотами designed for deterministic industrial control, embedded monitoring, distributed measurement, and FPGA-based edge processing applications. Built on the NI CompactRIO platform, the cRIO-9041 combines a real-time Intel Atom processor, programmable Xilinx FPGA architecture, and modular C Series I/O into a compact industrial controller optimized for harsh environments.

Unlike traditional PLC systems that rely mainly on CPU-based logic execution, the cRIO-9041 integrates FPGA-level hardware timing and deterministic processing directly into the control architecture. This allows engineers to implement ultra-low-latency control loops, synchronized acquisition systems, industrial communication protocols, and custom hardware logic within the same embedded platform.

The controller is widely used in:

• Промышленные системы автоматизации
• Мониторинг состояния оборудования
• Robotics and motion control
• Automotive HIL systems
• Distributed measurement architectures
• Smart grid and energy systems
• Embedded OEM control platforms
• Industrial IoT edge systems

Архитектура процессора и ПЛИС

The cRIO-9041 uses an Intel Atom E3930 dual-core processor running the Операционная система NI Linux Real-Time, providing deterministic execution behavior for industrial real-time applications. The system includes:

• 1.3 GHz dual-core CPU
• 2 ГБ DDR3L ОЗУ
• 4 ГБ встроенной памяти
• Xilinx Kintex-7 70T FPGA

Бортовой Kintex-7 FPGA enables:

• Hardware-level timing control

• Запись вибрации
• Измерение температуры
• Motion control interfaces
• Промышленные коммуникационные модули

This modular architecture allows the controller to function simultaneously as:

1. Детерминированный промышленный контроллер
2. A distributed real-time acquisition system
3. An FPGA-based edge processing node

Unlike fixed-function PLC hardware, CompactRIO systems can be customized for application-specific industrial requirements.
