BECKHOFF CX2500 / CX2030 / CX2550 / CX2100 / EL6070 / EK1110 – High-Performance Embedded PC Controller | CX Series Platform
Engineering Background: The BECKHOFF CX Series represents the gold standard in PC-based control technology, combining Intel® Core™ processor performance with native EtherCAT fieldbus integration. Designed for demanding machine builders and system integrators, these modules eliminate the need for separate IPC cabinets while delivering deterministic real-time control via TwinCAT 3 runtime.
Product Positioning: This multi-SKU listing covers the complete CX2000 family ecosystem — from the CX2030/CX2050 base units and CX2500 power supply modules, to the EL6070 license key terminal and EK1110 EtherCAT extension coupler. Together they form a fully integrated, DIN-rail-mounted control platform suited for high-axis-count motion, robotics, and process automation.

Proven Application Environments
- Multi-Axis CNC & Robotics: CX2050/CX2550 base units running TwinCAT NC PTP / NC I for coordinated motion control of 16–64 servo axes over EtherCAT.
- Packaging Machinery: CX2030 paired with EK1110 coupler to extend I/O across long conveyor lines without additional fieldbus masters.
- Semiconductor & Electronics Manufacturing: Deterministic sub-1 ms cycle times enable precision dispensing, pick-and-place, and vision-triggered motion.
- Building Automation & HVAC: CX2100 power supply modules provide clean 24 V DC distribution to distributed I/O terminals in BMS panels.
- Water & Wastewater Treatment: Fanless CX2030 with SSD storage for continuous 24/7 SCADA and PLC operation in humid environments.
- Renewable Energy: Wind turbine nacelle controllers and solar inverter management using TwinCAT PLC runtime with IEC 61131-3 programming.
- Software License Management: EL6070 terminal stores TwinCAT software licenses securely on-module, surviving PC replacement without re-licensing.
Engineering Advantages
- PC-Based Real-Time Control: TwinCAT 3 runtime runs as a real-time extension of Windows, achieving <100 µs jitter — no dedicated DSP required.
- Scalable Performance: Dual-core CX2030 to quad-core CX2550 covers entry-level to high-performance motion without changing the software architecture.
- Native EtherCAT Master: Eliminates external fieldbus cards; the Ethernet port becomes a deterministic EtherCAT master at no additional hardware cost.
- License Portability via EL6070: Hardware-bound TwinCAT licenses stored in the EL6070 terminal survive CPU replacement — critical for long-lifecycle machines.
- Seamless I/O Expansion via EK1110: Extend EtherCAT segments up to 100 m with standard Cat 5e cable, enabling distributed I/O without topology constraints.
- Compact DIN-Rail Form Factor: All modules mount on standard 35 mm DIN rail, reducing panel space by up to 60% vs. traditional rack-mount IPCs.
- Long-Term Availability: BECKHOFF commits to 10+ year product lifecycle for CX2000 series, reducing obsolescence risk for OEM machine builders.
System Architecture & Signal Flow
A typical CX Series control node is structured as follows:
- Power Entry: CX2100 power supply module → 24 V DC bus to base unit and I/O terminals
- CPU Module: CX2030 / CX2050 / CX2550 running TwinCAT 3 PLC + NC runtime
- License Terminal: EL6070 inserted in the local E-bus — stores TwinCAT runtime license on-chip
- Local I/O: EL series terminals (digital, analog, encoder, safety) connected via E-bus at 100 Mbit/s
- Remote I/O Extension: EK1110 EtherCAT coupler bridges to remote I/O stations over standard Ethernet cable
- HMI / SCADA: TwinCAT HMI or third-party SCADA via OPC UA / ADS protocol over standard LAN port

Technical FAQ
Q: Can the CX2030 and CX2050 run TwinCAT/BSD instead of Windows?
A: Yes. BECKHOFF supports TwinCAT/BSD (a FreeBSD-based RTOS) on CX2000 series, offering a license-free OS option with full TwinCAT 3 runtime support.
Q: How many EtherCAT slaves can a CX2050 master?
A: Theoretically up to 65,535 EtherCAT nodes per segment; practical limits depend on cycle time and process data size. Typical installations run 128–512 slaves comfortably.
Q: Is the EL6070 license terminal interchangeable between CX units?
A: Yes. The EL6070 stores the license independently of the CPU. Moving it to a replacement CX unit transfers the TwinCAT license without re-activation.
Q: What is the difference between EK1100 and EK1110?
A: The EK1100 is a standard EtherCAT coupler (IN port only); the EK1110 adds an EtherCAT extension port (OUT), enabling daisy-chain topology for remote I/O segments.
Q: Do you supply the CX2500 power supply module separately?
A: Yes. The CX2500 is available as a standalone module for system expansion or replacement. Contact us with your required quantity.
