Beckhoff CX5140 Embedded PC with Intel Atom Processor
Overview
The Beckhoff CX5140 is a compact, fanless embedded PC built around an Intel Atom quad-core processor running at 1.91 GHz, bringing genuine multi-core computing performance to the embedded PC segment for demanding automation applications. As part of Beckhoff’s CX5100 series, the CX5140 is designed to run TwinCAT PLC and motion control projects, with or without visualization, directly on the controller, eliminating the need for a separate industrial PC in many machine control architectures.
For manufacturing, material handling, and process automation facilities across Oman and the wider GCC, the CX5140 provides a compact, DIN-rail mountable control platform that combines PC-based computing power with the modular I/O flexibility of Beckhoff’s Bus Terminal and EtherCAT Terminal systems. Seven Star LLC supplies the Beckhoff CX5140 embedded PC to customers across Muscat, Sohar, Salalah, and the Sultanate of Oman as a trusted supplier of Beckhoff products, providing controllers with full documentation and technical support.
Measurement and Operating Principle
The CX5140’s Intel Atom quad-core processor executes TwinCAT real-time control software directly, converting the embedded PC into a soft PLC and, where required, a motion controller capable of interpolating axis movements for coordinated multi-axis applications. With 4 GB of DDR3 RAM (non-expandable) and an integrated 1-second UPS backed by CFast card storage, the CX5140 can save up to 1 MB of data to the CFast card during brief power interruptions, safeguarding process state and preventing data loss during unplanned power events.
Depending on the TwinCAT runtime environment installed, the CX5140 executes PLC-only projects, combined PLC/motion control projects, or full motion control applications with interpolating axis movements, giving machine builders flexibility to scale the controller’s role from simple sequencing to complex synchronized motion without changing hardware platforms.
Engineering Design of the Beckhoff CX5140
The CX5140 provides two RJ45 Gigabit Ethernet ports (10/100/1000 Mbit/s), a DVI-I display output, four USB 2.0 ports, and an optional interface slot for additional connectivity such as fieldbus master/slave modules, RS232/RS485 serial interfaces, or an additional DVI-D or DisplayPort output. Its fanless design and low power consumption make it well suited to control cabinet installations where dust, vibration, and limited cooling airflow would compromise the reliability of conventional fan-cooled industrial PCs.
The CX5140’s housing integrates directly with Beckhoff’s Bus Terminal (K-bus) and EtherCAT Terminal (E-bus) systems, allowing the controller to be paired with hundreds of I/O terminal types covering digital, analog, temperature, communication, and specialty signal types, all mounted on a single DIN rail assembly. This modular architecture lets system integrators build a precisely sized control and I/O solution for each machine without the cost and footprint of a separate PLC chassis and remote I/O system.

Industrial Applications
The CX5140 is widely used in packaging machinery, material handling systems, and general manufacturing automation applications where a compact, DIN-rail mounted controller with integrated PC-based computing and motion control capability is required. Its combination of processing power and modular I/O integration makes it particularly well suited to machine builders who need a scalable control platform across a product range with varying I/O counts and motion complexity.
Across Oman’s manufacturing and industrial automation sectors, including facilities supporting the Sohar and Salalah economic zones, the CX5140 gives control engineers a compact, reliable embedded PC platform for PLC and motion control applications without the space and cost of a full industrial PC and separate PLC. As a trusted supplier of Beckhoff products, Seven Star LLC supports these projects throughout the Sultanate of Oman with controllers supplied on request, I/O configuration guidance, and technical support.

CX5140 Ordering Codes Explained
Beckhoff sells the CX5140 as a CPU module with a four-digit suffix that fixes the operating system and the TwinCAT runtime. CX5140-0100 is supplied without operating system and without TwinCAT. The third digit selects the operating system: 011x is Windows Embedded Compact 7, 012x and 013x are Windows Embedded Standard 7 in 32 and 64 bit, 014x to 017x are Windows 10 IoT Enterprise 2016 LTSB and 2019 LTSC, CX5140-0185 is TwinCAT/BSD, and CX5140-0190 and -0195 are Windows 10 IoT Enterprise 2021 LTSC 64 bit.
The last digit selects the runtime: 0 means no TwinCAT, 1 TwinCAT 2 PLC, 2 TwinCAT 2 NC PTP, 3 TwinCAT 2 NC I, and 5 TwinCAT 3 runtime (XAR) preinstalled without licenses, which are ordered separately. Beckhoff notes that Windows Embedded Compact 7 uses only one CPU core, and that extended support for Windows Embedded Compact 7, Windows Embedded Standard 7 and Windows 10 IoT Enterprise 2016 LTSB has ended. For a replacement unit, quote the full code from the device label so the operating system and runtime match the existing project.
Factory-Fitted Optional Interfaces and Storage Cards
The optional interface is fitted ex factory and has to be specified with the order. Beckhoff lists CX5140-N010 (additional DVI-D), N011 (DisplayPort), N020 (audio), N030 (RS232) and N031 (RS485, with sub-variants for echo, termination and RS422), plus fieldbus options M112 (2 × EtherCAT master), B110 (EtherCAT slave), M310 and B310 (PROFIBUS master and slave), M510 and B510 (CANopen master and slave) and M930 and B930 (PROFINET RT controller and device). The DVI-D and DisplayPort options are not supported by Windows Embedded Compact 7 or TwinCAT/BSD.
CFast and microSD cards are not included with the CPU module. According to Beckhoff, Windows Embedded Compact 7 and TwinCAT/BSD need a CFast card of at least 20 GB, while Windows Embedded Standard 7 and Windows 10 IoT Enterprise need at least 40 GB; cards from 20 GB to 320 GB are listed as accessories. The I/O side accepts either E-bus or K-bus terminals with automatic recognition and supplies up to 2 A to the terminal bus. For hazardous-area approvals (ATEX, IECEx, cFMus) the ordering option CX2900-0107 is required.
Why Choose Seven Star LLC for Beckhoff Embedded Industrial PCs
An embedded industrial PC’s real value in an automation panel depends on its I/O module configuration and operating system genuinely matching your control application, since an underspecified processor or memory configuration limits future expansion while an oversized one adds unnecessary cost to a panel build.
