Beckhoff CX5020-0111 CPU Base Unit – Industrial Embedded PC
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Beckhoff CX5020-0111 is an industrial embedded PC CPU base unit for existing CX5000 control systems. It provides a 1.6 GHz Intel Atom Z530 single-core processor, 512 MB RAM, 128 MB CompactFlash storage and 1 MB retentive memory for TwinCAT 2 PLC runtime applications. Microsoft Windows Embedded CE 6.0 is used as the operating environment for this configuration. The compact DIN-rail unit features passive cooling, an integrated power supply and UPS, and supports control of Beckhoff EL-series EtherCAT Terminals through its integrated E-bus interface.
When replacing a CX5020-0111, the software environment and connected hardware must match the existing installation. A compatible CompactFlash card can carry the project and persistent data to a replacement unit after suitable power-down procedures. Check the TwinCAT 2 version, Windows Embedded CE 6.0 environment, E-bus configuration and CompactFlash compatibility before commissioning the spare. Two RJ45 Ethernet ports, four USB 2.0 Type-A ports, a DVI-D output and the CompactFlash card slot provide the connection points used for networking, peripherals, visualization and data transfer.
The CX5020-0111 provides PWR, TC, Flash and Bus Status indicators for monitoring power, TwinCAT state, CompactFlash access and bus or fieldbus state. During troubleshooting, review these indicators together with the installed CompactFlash card, TwinCAT configuration, E-bus hardware and network connections. As a discontinued product in Beckhoff service phase, this CPU base unit is intended for maintaining existing CX5000 installations; a tested repair or exchange unit can support restoration when an internal controller fault interrupts production.

Programming and Configuration
The CX5020-0111 runs TwinCAT 2 PLC runtime applications on Microsoft Windows Embedded CE 6.0. Replacement commissioning therefore depends on retaining the established TwinCAT 2 software environment and the configuration used by the existing CX5000 installation.
The 128 MB CompactFlash storage and CompactFlash card slot support transfer of the project and persistent data to a replacement unit. After suitable power-down procedures, use a compatible CX5020-0111 CompactFlash card together with matching hardware, operating system, TwinCAT version and E-bus configuration.
Communication and System Integration
An integrated E-bus interface connects the CPU base unit directly to Beckhoff EL-series EtherCAT Terminals. The integrated EtherCAT fieldbus master and control network interface support compact distributed I/O architectures without a separate fieldbus coupler.
Two RJ45 Ethernet ports support 10/100/1000 Mbit/s networking and EtherCAT-related connectivity. Four USB 2.0 Type-A ports support peripherals, while the 1 x DVI-D output provides a connection for an attached display or visualization panel.
Diagnostics and Status Indication
The front-panel indicators identify the main operating areas of the CPU base unit: PWR indicates power supply status, TC indicates TwinCAT status, Flash indicates CompactFlash access, and Bus Status uses two LED indicators for bus status and fieldbus state.
For first-line troubleshooting, compare the indicator states with the installed CompactFlash card, TwinCAT configuration, E-bus hardware and Ethernet connections. These checks help distinguish power, runtime, storage, bus and network-related issues before selecting a repair or exchange unit.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| PWR | Power supply status indicator | |
| TC | TwinCAT status indicator | |
| Flash | CompactFlash access indicator | |
| Bus Status | Two LED indicators for bus status and fieldbus state |
Replacement and Spare Part Considerations
For a compatible replacement, match the Beckhoff CX5020-0111 part number and confirm the CX5000 hardware arrangement, integrated E-bus configuration, TwinCAT 2 runtime, Windows Embedded CE 6.0 environment and CompactFlash card. Another CX5020 variant should not be substituted without checking the software, I/O bus and storage configuration.
A spare is not necessarily ready for immediate operation. Transfer the compatible CompactFlash card after suitable power-down procedures and confirm that the project, persistent data, operating system, TwinCAT version and connected EL-series EtherCAT Terminals align with the original controller. ABC Industrial Parts can support repair and exchange requirements for discontinued CX5000 CPU base units.
