Description

The BECKHOFF CX9020-N031 is a compact, DIN-rail-mountable Embedded PC designed for mid-range PLC and Motion Control applications. Powered by an ARM Cortex-A8 processor, this basic CPU module integrates a control unit with direct I/O support and built-in communication interfaces for industrial environments.

The CX9020-N031 variant is factory-configured with a dedicated RS485 system interface. This interface features a 9-pin D-sub socket configured as an end point with active termination and no echo, allowing direct serial communication with external field devices, legacy controllers, or peripheral instrumentation.

With its automatic bus detection capability, the unit directly interfaces with both Beckhoff Bus Terminals (K-bus) and EtherCAT Terminals (E-bus). This dual-bus support enables flexible, scalable control architectures without requiring separate bus coupler modules.

Features

ARM Cortex-A8 processor (1 GHz) for stable industrial control execution
Factory-integrated RS485 serial interface (9-pin D-sub socket, end point configuration with active termination and no echo)
Dual-system I/O bus interface with automatic detection of E-bus (EtherCAT Terminals) and K-bus (Bus Terminals)
Built-in dual RJ45 Ethernet interfaces with an internal switch
Compact housing design optimized for standard DIN-rail mounting

Applications

Decentralized machine control and modular automation systems
Serial communication and peripheral device integration via RS485 protocols
Building automation, HVAC control, and infrastructure monitoring
Compact motion control and localized PLC installations

Installation Guidelines

Verify the exact model and specification matches your system requirements before installation.
Ensure the entire control cabinet and power supply are de-energized before mounting.
Snap the Embedded PC onto a clean, grounded 35 mm DIN rail (EN 60715).
Connect the 24 V DC power supply to the designated power terminals.
Connect the RS485 communication lines to the 9-pin D-sub socket, ensuring correct shielding.
Attach the compatible EtherCAT Terminals (E-bus) or Bus Terminals (K-bus) directly to the right side of the module.
Energize the system and perform initial software configuration and system commissioning.
