Eaton XC-CPU202-EC4M-8DI-6DO-XV – PLC CPU with EtherCAT and Integrated I/O

The Eaton XC-CPU202-EC4M-8DI-6DO-XV is a high-performance programmable logic controller from the XC200 series, designed for demanding automation tasks. It combines a powerful CPU with integrated EtherCAT master functionality and onboard digital I/O, providing a compact yet scalable control solution for machines and systems.

Key Features

• Integrated EtherCAT Master: Enables real-time communication with EtherCAT drives, I/O modules, and other devices. The interface supports up to 4 EtherCAT slaves (EC4M) and delivers deterministic cycle times.

• Onboard I/O: 8 digital inputs (24 V DC, 3 ms filter) and 6 digital outputs (transistor, 0.5 A each) allow direct connection of sensors and actuators without additional modules for small applications.

• High Processing Power: 32-bit CPU with fast instruction execution, suitable for complex logic and motion control.

• CODESYS Programming: Supports all IEC 61131-3 languages (LD, FBD, ST, IL, SFC) and provides extensive library support.

Communication Interfaces

• Ethernet: 2-port switch for programming, HMI communication, and network integration (Modbus TCP, EtherNet/IP).

• EtherCAT: Dedicated master port (RJ45) for high-speed fieldbus.

• Serial: RS232/RS485 configurable interface for legacy devices.

• USB: Programming port and host for data logging.

Technical Specifications

• Power Supply: 24 V DC (±20%)

• Digital Inputs: 8, sink/source, 24 V DC, 3 ms filter (configurable)

• Digital Outputs: 6, transistor, 24 V DC, 0.5 A per channel, protected against short circuit

• Program Memory: 256 kB (for application code)

• Data Memory: 64 kB retentive, 512 kB non‑retentive

• Cycle Time: Typically < 0.1 ms for 1k instructions

• Operating Temperature: 0°C to +55°C

• Dimensions (WxHxD): 72 x 90 x 70 mm (suitable for DIN rail mounting)

Scalability and Expansion

The XC-CPU202-EC4M-8DI-6DO-XV can be expanded with a wide range of XC series modules: digital/analog I/O, temperature measurement, communication modules, and more. Expansion is done via the internal backplane, allowing up to 64 modules per station. The integrated EtherCAT master also enables distributed I/O and drives over long distances.

Typical Applications

This CPU is ideal for:

• Packaging and handling machines with multi‑axis motion

• Assembly lines requiring fast communication

• Printing and textile machinery

• Small to medium-sized automation systems with distributed I/O
