Beckhoff CX5020-0110: Compact Embedded PC for Industrial Automation

The Beckhoff CX5020-0110 is a robust, compact embedded PC from the CX5000 series, designed for DIN rail mounting in industrial control cabinets. This CPU module features an Intel Atom Z510 processor running at 1.1 GHz, providing a balance of performance and energy efficiency for demanding automation tasks. The CX5020-0110 serves as a powerful control platform that can be transformed into a full-featured PLC and Motion Control system through Beckhoff's TwinCAT automation software. With its fanless design and passive cooling architecture, the unit achieves a maximum power consumption of only 13 W, making it suitable for use in thermally constrained environments. The module supports both Windows CE and Windows Embedded Standard operating systems, providing flexibility for different application requirements. The minimum requirement for Windows Embedded Standard 7 P (32 Bit) is a CX5020 with 1 GB RAM installed ex factory and an 8 GB Compact Flash card. The 1-second UPS persistent data feature ensures critical data is retained during unexpected power interruptions.

Technical Specifications

The CX5020-0110 is equipped with an Intel Atom Z510 processor operating at 1.1 GHz, complemented by 1 GB of DDR2 RAM for smooth multitasking and real-time processing. The processor features hyperthreading technology, enabling efficient handling of parallel automation tasks. The unit includes 512 MB of expandable microSD storage for the operating system and application software. Two independent Gigabit Ethernet ports provide high-speed network connectivity for fieldbus communication and remote monitoring. The module includes DVI-D, USB 2.0 interfaces, and an optional fieldbus connection for PROFIBUS, CANopen, or RS232/RS422/RS485. The CPU module weighs approximately 575 grams and features passive cooling, eliminating the need for fans that could accumulate dust and fail over time.

TwinCAT Automation Software

The TwinCAT automation software transforms the CX5020-0110 into a powerful PLC and Motion Control system that can be operated with or without visualization. TwinCAT 3 XAR (eXtended Automation Runtime) provides real-time execution of control programs with cycle times as low as 50 microseconds for demanding motion control applications. The software supports all five IEC 61131-3 programming languages including Ladder Diagram, Structured Text, Function Block Diagram, Instruction List, and Sequential Function Chart. The CX5020-0110 can be equipped with different hardware and software options, including TwinCAT 2 PLC runtime and TwinCAT 2 NC-PTP runtime for multi-axis motion control.

I/O Expansion and Fieldbus Connectivity

The CX5020-0110 supports flexible I/O expansion through Beckhoff's extensive range of E-bus and K-bus terminals. The module can interface with a wide variety of digital and analog I/O modules, specialty modules for position measurement, and communication interfaces. Optional fieldbus connections are available for PROFIBUS, CANopen, RS232, RS422, and RS485, enabling integration into existing industrial networks. The two Gigabit Ethernet ports can be used for real-time EtherCAT communication, TCP/IP networking, or redundancy configurations.

Environmental and Mechanical Data

The CX5020-0110 is designed for industrial environments with an operating temperature range of 0°C to 55°C and storage temperature from -20°C to 70°C. The unit meets CE and UL standards for industrial control equipment and is RoHS compliant. The DIN rail mounting design allows quick installation in control cabinets, and the compact form factor minimizes space requirements. The module includes a 1-second UPS persistent data feature that ensures critical application data is retained during short power interruptions. This feature is particularly valuable for applications requiring data integrity during unstable power conditions.

Typical Applications

The Beckhoff CX5020-0110 is deployed in a wide range of industrial automation applications including packaging machinery, assembly lines, material handling systems, laboratory automation, and test stand control. Its combination of PC-based computing power and real-time control capabilities makes it suitable for applications requiring data logging, HMI visualization, and complex motion control on a single platform. The module is often used as a central controller in distributed automation architectures, communicating with remote I/O stations via EtherCAT or other fieldbus protocols. In machine building applications, the CX5020-0110 provides the processing power needed for high-speed logic execution while maintaining deterministic response times.
