KL1404 BECKHOFF Central unit

Product  Description：

Beckhoff Central Units, primarily represented by their Embedded PCs (such as the CX series) and Industrial PCs (IPCs), serve as the primary controllers for PC-based automation technology. These units combine the industrial hardiness of a classic PLC with the high performance and flexibility of a modern computing architecture. Running on TwinCAT software, a Beckhoff Central Unit executes real-time PLC, motion control, robotics, and HMI tasks simultaneously on a single processor platform, utilizing EtherCAT as its primary ultra-high-speed communication backbone.

Product Parameters

The technical characteristics of Beckhoff Central Units reflect their high-performance PC-based heritage:

• Processor Architecture: Scalable processing power ranging from energy-efficient ARM Cortex CPUs for compact applications to high-end Intel Core and Xeon multi-core processors for complex machines.

• Operating Memory: Equipped with high-speed RAM, typically from 512 megabytes up to 64 gigabytes or more, depending on the computational demands of the system.

• Storage Media: Utilizes solid-state storage technologies including microSD cards, CFast cards, or standard SSDs to ensure high vibration resistance and longevity.

• Operating System Options: Runs robust, real-time capable operating systems such as TwinCAT/BSD, Windows 10 IoT Enterprise, or Windows Embedded Compact.

• System Interfaces: Integrated with gigabit Ethernet ports, USB connections, DVI or DisplayPort for HMI connection, and optional fieldbus interfaces like PROFINET or EtherNet/IP.

• I/O Bus Connection: Features a direct backplane interface that automatically detects and communicates with standard Beckhoff Bus Terminals or high-speed EtherCAT Terminals.

Product Advantages

Beckhoff Central Units offer distinct operational benefits by breaking away from traditional proprietary hardware constraints:

• Software-Based Controller: By using TwinCAT software for all control logic, the hardware can be easily upgraded or replaced over time without rewriting the underlying application code.

• Extreme Processing Speed: Multi-core processing capability allows time-critical motion control loops to run on dedicated CPU cores, achieving cycle times well under 100 microseconds.

• Seamless EtherCAT Integration: Acts as an ideal EtherCAT master, enabling microsecond-level synchronization across thousands of distributed I/O points and servo drives.

• Multi-Functional Capabilities: A single central unit can manage standard logic control, safety-rated functions (TwinSAFE), advanced motion control, vision processing, and cloud connectivity simultaneously.

• Compact and Fanless Design: Many models in the CX series utilize optimized thermal management to offer fanless operation in a DIN rail mountable form factor, enhancing reliability by removing moving parts.

Product Applications

These PC-based central units are deployed in advanced automation scenarios that require high data throughput and precise timing:

• High-Speed Packaging: Coordinating electronic camming, flying shears, and delta robots on high-throughput flow-wrapping and cartoning lines.

• Wind Power Generation: Managing the real-time pitch control, grid synchronization, and comprehensive data logging for large-scale wind turbines.

• Semiconductor and Electronics: Controlling high-precision pick-and-place gantry systems, wafer handling tools, and automated optical inspection machines.

• Smart Building Automation: Serving as the main supervisor for large commercial buildings, integrating HVAC, lighting control, and energy monitoring via diverse communication protocols.

• Additive Manufacturing: Driving the complex, multi-axis interpolation and laser synchronization required for industrial 3D printing and laser cutting systems.

Important Precautions

To protect the computing hardware and maintain deterministic control, the following handling and installation rules must be observed:

• Proper Shutdown Procedures: Because these units run PC operating systems, abruptly cutting off power can lead to file system corruption. Always implement an uninterruptible power supply (UPS) or use the TwinCAT write filter to protect data on the storage media.

• Storage Media Longevity: Only use industrial-grade storage cards approved by Beckhoff. Standard consumer-grade flash memory cannot handle the high read/write cycles required for continuous industrial data logging.

• Thermal Environment: Adhere to the specified mounting orientation, which is typically vertical on a DIN rail, to ensure natural convection airflow. Blocked cooling vents or incorrect positioning will cause the CPU to throttle its speed or shut down due to overheating.

• Grounding and Shielding: Maintain a low-impedance connection between the central unit housing and the control cabinet's functional earth. Shielded cables must be used for all Ethernet and EtherCAT connections to prevent electromagnetic noise from causing packet drops.

• Software Configuration: When allocating CPU cores within TwinCAT, ensure that at least one core is left completely free for the operating system's background tasks. Allocating 100 percent of the CPU resources to the real-time control loop will cause the operating system to freeze and make remote diagnostics impossible.
