Equipped with an 800 MHz ARM Cortex-A9 processor, 512 MB RAM, and an expandable microSD card, it delivers significantly higher performance than previous CX8000-series controllers. Its integrated Ethernet port and two-port switch support protocols such as real-time Ethernet, ADS, UDP/TCP, and EAP, enabling versatile communication architectures. During startup, the module automatically detects whether E-bus or K-bus I/O terminals are attached, allowing seamless integration with Beckhoff's extensive terminal portfolio. Combined with Windows Embedded Compact 7 and TwinCAT 3 runtime, the CX8190 provides a reliable, compact, and flexible PLC-class controller for a broad range of industrial applications. Key Features: Dual Ethernet architecture: includes one standard Ethernet port and a two-port switched bus interface, enabling real-time Ethernet, ADS TCP/UDP, and EtherCAT Automation Protocol communication in distributed systems. Automatic I/O bus detection: supports both Beckhoff E-bus (EtherCAT Terminals) and K-bus (Bus Terminals), identifying the attached I/O system automatically at startup for simplified installation. TwinCAT 3 programmability: fully compatible with TwinCAT 3 engineering tools and runtime, providing deterministic control, motion capabilities, and flexible expansion with TwinCAT add-on modules. Robust ARM Cortex-A9 performance: 800 MHz single-core processor delivers reliable execution for PLC logic, motion tasks, communication stacks, and real-time automation functions. Integrated persistent data protection: features a built-in 1-second UPS to secure 1 MB of persistent data in the event of power loss, safeguarding critical process information. Wide operating temperature and environmental durability: functions from −25 to +60 °C with industrial-grade vibration and EMC compliance, making it suitable for harsh environments. Compact IP20 design: optimized for cabinet installation with minimal footprint while maintaining full PC-based control functionality. Expandable storage and flexible memory options: includes a 512 MB microSD card (expandable up to 8 GB) for application data, logging, and program storage. The CX8190 delivers the reliability and precision required for compact PC-based control, high-speed Ethernet communication, and flexible I/O integration in modern industrial automation systems.
