Overview
What are Embedded PCs?
Embedded PCs are compact industrial controllers that combine the processing power of a standard PC with the ruggedness and modularity of a PLC. Unlike consumer-grade hardware, these units are designed for 24/7 operation in harsh environments, featuring fanless cooling, solid-state storage, and high resistance to electromagnetic interference (EMI). They typically run real-time operating systems or industrial versions of Windows (such as Windows 10 IoT) to execute complex automation tasks, including high-speed motion control, data logging, and IoT gateway functions.
Main Manufacturers
At PALM Parts Solution, we specialize in high-performance embedded computing hardware from industry leaders. Our primary stock includes:
- Beckhoff: The pioneer of PC-based control technology. Beckhoff units are synonymous with the CX series and EtherCAT integration, offering a modular approach where the CPU, power supply, and I/O are combined on a single DIN rail.
Typical Applications
Embedded PCs are utilized in sectors where high-speed processing and small form factors are critical. Common applications include:
- High-Speed Motion Control: Utilizing TwinCAT software to coordinate multiple servo axes (such as AX5000 drives) with microsecond precision.
- Machine Vision: Processing high-resolution images on the factory floor for quality inspection.
- IIoT Gateways: Acting as a bridge between legacy fieldbus systems and cloud platforms via OPC UA or MQTT.
- Protocol Conversion: Managing communication between disparate systems like PROFINET, EtherNet/IP, and EtherCAT.
Selection Guide
When selecting an Embedded PC for your facility, consider the following technical specifications:
- Processing Power: Choose between entry-level Intel Atom processors for basic I/O and data collection, or Intel Core i-series (i3, i5, i7) for complex multi-axis motion and visualization.
- Modular Connectivity: Determine if you require built-out interfaces for DVI/DisplayPort, additional USB ports, or specific fieldbus connections.
- Operating System: Ensure the hardware supports your required software environment, whether it is Windows 10 IoT Enterprise, TwinCAT/BSD, or Linux-based builds.
- Environment: Verify the IP rating and operating temperature range, especially if mounting the unit in an uncooled outdoor enclosure.
Popular Product Families
We maintain an inventory of the most widely used industrial series, including:
- Beckhoff CX5100/CX5200: Compact, multi-core Intel Atom units for mid-range control tasks.
- Beckhoff CX2000 Series: High-end modular PCs with Intel Core processors for the most demanding applications.
- Beckhoff CX9020: Specialized, compact controllers for small-scale automation projects.
Replacement & Compatibility
Upgrading or replacing an embedded controller often involves migrating software licenses and fieldbus configurations. For example, if you are moving from an older CX1020 unit, the CX5200 series often provides a compatible modern footprint with significantly higher processing overhead. While Beckhoff systems are proprietary in their hardware modularity, their support for open standards like OPC UA allows them to integrate into environments running Siemens SIMATIC S7 or Allen-Bradley ControlLogix systems.

Frequently asked questions
What is the difference between an Industrial PC and an Embedded PC?
Embedded PCs are often more compact, fanless, and have higher vibration/temperature tolerances compared to traditional IPCs. While a standard IPC uses a tower or rackmount chassis, an Embedded PC is typically DIN-rail mounted and integrates I/O interfaces directly into the controller housing, making them ideal for space-constrained control cabinets.
Which communication protocols do Beckhoff Embedded PCs support?
Most Beckhoff Embedded PCs, such as the CX2000 or CX5100 series, support EtherCAT as the primary real-time communication backbone. However, they can also support PROFINET, EtherNet/IP, Modbus TCP, and OPC UA through optional communication interfaces or software configuration.
How do I select a replacement for a CX series controller?
Embedded PCs are modular. When replacing a unit, you must match the CPU performance class (e.g., Intel Atom vs. Core i7), the amount of RAM, the operating system (Windows 10 IoT, TwinCAT/BSD), and the specific I/O bus interface (E-bus for EtherCAT or K-bus for terminal bus).
Are these units fanless?
Yes. One of the primary advantages of the Beckhoff CX series is that they are designed for fanless operation. They utilize advanced heat dissipation through their aluminum housing, allowing them to operate in environments from -25°C to +60°C without moving parts that could fail.
What is the standard voltage requirement for an Embedded PC?
Most industrial embedded controllers, including the CX series, operate on a standard 24 V DC power supply. It is important to calculate the total power consumption based on the CPU load and the number of attached I/O terminals to ensure the power supply unit (PSU) is correctly sized.
