Description

The BECKHOFF CX2020-0112 is an Embedded PC basic CPU module designed for high-performance DIN rail mounting. Equipped with an Intel Celeron 827E single-core processor running at 1.4 GHz, this industrial controller provides dependable processing capabilities for medium-to-high complexity PLC and motion control tasks. Currently in its service phase, this module is a stable and mature automation component ideal for system maintenance, direct machine replacements, and legacy line retrofits.

This controller features 2 GB of DDR3 RAM as standard and 128 kB of integrated, non-volatile NOVRAM for persistent data storage without requiring an external UPS. The basic CPU module connects directly to a system power supply module from the CX2100 series, allowing automatic detection and adaptation to either E-bus (EtherCAT Terminals) or K-bus (Bus Terminals) I/O systems. Interface options include dual independent Gigabit Ethernet ports, a DVI-I video output, four USB 2.0 ports, and a factory-configurable option slot for flexible interface expansion.

Features

• Single-core Intel Celeron 827E processor operating at 1.4 GHz for reliable, deterministic control.
• 2 GB DDR3 RAM main memory for robust application handling.
• 128 kB integrated NOVRAM for reliable storage of critical variables and status data during power loss.
• Dual RJ45 10/100/1000 Mbit/s independent Ethernet interfaces to segregate control and corporate networks.
• Support for automatic recognition and execution of E-bus (EtherCAT) and K-bus (Bus Terminal) I/O structures.
• Modular hardware design allowing the addition of fieldbus, serial, or network expansion interfaces.
• Passive cooling design under standard environmental conditions.

Applications

• Industrial PLC execution and multi-axis motion control applications.
• Direct replacement of existing machine controllers in legacy installations.
• Distributed control systems needing localized processing power with dual-network segment architecture.
• Data logging and HMI integration utilizing local high-speed processing and display outputs.

Installation Guidelines

1. Ensure all electrical power is completely switched off before mounting or servicing the system.
2. Mount the CX2020-0112 CPU module onto a standard 35 mm DIN rail (EN 60715) with an integrated CX power supply unit.
3. Align the slide mechanism with the DIN rail and push the module firmly until the latch snaps securely in place.
4. Ensure that adjacent system modules (such as I/O terminals and power supplies) are properly aligned and their lateral contact rails engage seamlessly.
5. Connect the ground / functional earth wire to the power supply unit terminal to prevent electromagnetic interference.
6. Verify that the ventilation slots on the top and bottom of the housing remain clear to allow passive cooling.

Replacement Recommendations

When replacing a BECKHOFF CX2020-0112 unit in an existing control system, it is highly recommended to perform a full system backup before hardware removal. Ensure that the configuration, licenses, and variables stored on the CFast card are documented or backed up. Verify that the system's TwinCAT platform level (Level 50) and runtime version match the software configuration of your application before restoring power.
