Understanding the Human Factor in Industrial OS Selection
When industrial teams evaluate operating systems, they often focus on technical specs. However, the real question is simpler: “Can our engineers effectively use this?” Usability, training, and support matter as much as raw performance. A high-performing OS is meaningless if your team struggles to implement it.
Windows: Familiarity and Ease of Use
Windows dominates industrial automation for a reason. Its graphical interface is intuitive, and installation is straightforward. For teams without on-site IT specialists, this simplicity ensures rapid deployment. However, as automation systems grow connected, Windows’ general-purpose features may include unnecessary services, which can affect boot times and resource efficiency.
Linux: Flexibility Through Open Source
Linux is increasingly attractive in industrial environments due to its open-source nature. Developers can tailor the OS to include only essential components, creating lean, efficient systems. This modularity allows faster boot times, lower resource usage, and the ability to optimise for specific automation tasks. However, Linux requires command-line skills, which may pose challenges for teams accustomed to plug-and-play environments.
Navigating the End of Windows CE
The retirement of Windows Embedded Compact (CE) has pushed companies to reconsider OS choices for soft PLCs and industrial PCs. Modern Windows options like Windows 10 IoT fill the gap but often carry unneeded features. Linux, on the other hand, allows tailored distributions that include only runtime environments, essential tools, and connectivity features, enhancing performance for embedded applications.
Security Considerations: Windows vs Linux
Windows benefits from a large security support ecosystem, making it easier for teams to patch vulnerabilities. Linux takes a different approach, offering granular control over system components. Containerisation tools like Docker isolate applications—process control, data logging, and HMI—into secure, independent environments. This approach improves reliability, containment, and overall security, especially in multi-function industrial systems.
The Role of Real-Time Performance
Historically, Windows led in real-time performance for automation. However, Linux has caught up with advancements such as the PREEMPT_RT kernel patch, enabling precise timing for critical operations. Beckhoff’s TwinCAT software now runs on both BSD and Linux platforms, offering containerised, scalable automation environments without sacrificing real-time control or high-performance functionality.
Choosing the Right OS: No One-Size-Fits-All
There’s no universal answer when selecting an OS for automation. Consider your team’s skills, system scale, security needs, and long-term growth. Windows provides familiarity and broad support, while Linux offers efficiency, customisation, and containerised flexibility. Open, connected, and software-driven operations increasingly favor Linux, especially for forward-looking industrial applications.
My Insight as an Automation Engineer
From my perspective, adopting Linux or containerised OS platforms is not about replacing Windows entirely—it’s about future-proofing. Teams can start with familiar environments, then gradually introduce modular Linux systems for high-performance, secure, and scalable automation projects. This hybrid approach bridges usability and innovation without disrupting operations.
