Industrial PCs in transition: strategies and technologies for modern automation solutions

Industrial IT infrastructure is undergoing profound change. With the increasing networking of machines, the expansion of intelligent sensor technology and the growing demand for decentralised data processing, industrial PCs (IPCs) are gaining strategic importance. They act as an interface between operational technology (OT) and modern IT – reliable, robust and designed for longevity.

What is an industrial PC? – Definition and types

An industrial PC is a computer system designed for use in demanding environments that is significantly more robust than conventional consumer or office PCs. Typical features:

• Resistance to temperature, dust, moisture and vibration
• Durable components with stable series availability
• Flexible mounting options (wall, DIN rail, 19-inch rack, VESA)
• Wide range of connections (USB, LAN, COM, DIO, HDMI/DP)

The most important designs:

• Box PCs – compact, fanless, ideal for control cabinets and machine housings
• Panel PCs – industrial PCs with integrated touch display for HMI applications
• Edge PCs – powerful systems for local data processing and AI inference

Areas of application – requirements for IPCs in practice

Industrial PCs are used in almost all industries – from automation and logistics to building management systems. Requirements vary depending on the application:

• Manufacturing & machine control
• Near real-time connection of sensors, durable hardware for 24/7 operation, serial interfaces (e.g. RS232/422/485) and digital inputs/outputs
• Smart factory & edge applications
• Pre-processing of large amounts of data directly at the point of origin, fast network connection (2.5 Gbit/s LAN, Wi-Fi 6), analysis or visualisation functions
• Digital signage & building control
• Multi-display output, compact design, remote management and operational reliability even in continuous operation

Hardware architecture: What's inside a modern IPC

Compact housing & passive cooling

Fanless IPCs with ribbed aluminium housing enable passive cooling without moving parts – ideal for use in dusty or vibration-intensive environments.

Processor performance according to application requirements

Modern IPCs rely on energy-efficient CPUs such as Intel Celeron, Pentium or powerful Core i3, i5 and i7 processors. Additional hardware accelerators can be integrated for AI-based analyses or image processing.

Memory and mass storage solutions

With up to 96 GB of RAM and fast NVMe SSDs, current systems are equipped for complex tasks – from visualisation and logging to data pre-processing.

Connection variety for maximum flexibility

A wide range of I/O options ensure seamless integration into industrial networks:

• Multiple LAN ports (up to 2.5 Gbit/s)
• USB 3.2 / USB-C
• RS232/422/485 for serial communication
• HDMI, DisplayPort for multi-display setups
• Digital inputs/outputs (DIO)

Trends & strategic importance of industrial PC systems

Edge computing & AI on site

The trend is towards data processing directly at the edge of the network – where data is generated. Edge PCs enable fast responses, reduce latency and bandwidth requirements to the cloud, and lay the foundation for real-time decisions.

Cybersecurity in the industrial environment

As connectivity increases, so does the risk of attacks. Industrial PCs with TPM 2.0 support and Secure Boot help to better implement security requirements in production.

Long-term availability and ease of maintenance

Industrial PCs must be available and maintainable over the long term. Look for platforms with several years of series availability, stable BIOS support and manufacturer documentation for integrators.

The industrial PC as a strategic link in the value chain

Modern industrial PCs are much more than control units – they are data hubs, analysis devices and automation platforms all in one. Those who use IPCs today are laying the foundation for sustainable, scalable and future-proof industrial IT.

Take advantage of the possibilities offered by intelligent hardware to accelerate processes, make data usable and implement innovations in a targeted manner.
