BECKHOFF CX2040-0112 Embedded PC CPU Module

Description

The BECKHOFF CX2040-0112 is an Embedded PC CPU basic module belonging to the modular CX2000 hardware platform. This controller is equipped with an Intel Core i7 quad-core processor operating at 2.1 GHz, designed to handle highly demanding industrial automation applications that require high computing capacity, multi-core coordination, and complex control algorithms.

The system architecture utilizes a dedicated companion power supply module to connect and interface with I/O systems. The BECKHOFF CX2040-0112 features automatic recognition for both E-bus (EtherCAT Terminals) and K-bus (standard Bus Terminals) systems. Standard hardware interfaces include two independent RJ45 Gigabit Ethernet ports, four USB 2.0 interfaces, a DVI-I graphic output, and a modular option slot that accommodates an additional factory-configured interface.

For data retention and processing stability, the module includes 4 GB of non-expandable DDR3 RAM and 128 kB of integrated NOVRAM for non-volatile data storage. The operating system and user applications reside on a CFast flash card. Thermal management is maintained via an integrated cooling fan system equipped with ball bearings and active speed monitoring.

Installation Guidelines

1. Verify that the BECKHOFF CX2040-0112 CPU is paired with a compatible CX2100 series power supply module before mounting.
2. Ensure all system power supplies are turned off and locked out before starting installation on the DIN rail.
3. Mount the CPU module on a standard 35 mm DIN rail (EN 60715), ensuring the locking mechanism engages securely.
4. Connect the mandatory power supply module directly to the right side of the CPU to establish the internal system and E-bus/K-bus connections.
5. Connect the ground/PE terminal to ensure proper electrostatic discharge protection and noise immunity.
6. Insert the configured CFast card containing the appropriate operating system and TwinCAT boot project into the designated slot.
7. Apply 24 V DC power to the connected power supply module and monitor the diagnostic LEDs to confirm proper boot status.

Replacement Recommendations

1. Ensure all persistent variables and application projects are backed up from the existing CPU's NOVRAM and CFast card before replacement.
2. Power down the complete controller station before removing any modular block, expansion interface, or I/O terminal.
3. When installing the replacement BECKHOFF CX2040-0112 unit, confirm that the TwinCAT runtime licensing match is aligned with Platform Level 70 configuration parameters.
