IPCs im Dauereinsatz

What are IPCs in continuous operation?

Industrial PCs (IPCs) for continuous operation are computers specifically engineered for uninterrupted use under demanding environmental conditions. In intralogistics, you will find them at packing stations, control centers, sorting systems, conveyor control units, and pick workstations. Critically, a failure of these devices can directly cause process interruptions, throughput losses, or errors in order fulfillment — which is why availability and robustness are the most important selection criteria, not the purchase price.

How does this work in practice?

IPCs for continuous operation differ from standard commercial PCs in several key ways:

• Industrial design: Metal enclosures, fanless or redundant cooling, ingress protection ratings against dust and moisture (e.g., IP protection classes), and protection against vibration and temperature fluctuations.
• Long-term availability: Manufacturers often guarantee the availability of identical components and models for several years, which is critical for spare parts inventory and rapid replacement.
• Stable operating system image: Frozen, tested system images prevent unwanted changes caused by automatic updates. Security patches are applied in a controlled manner, not automatically.
• Remote management: Remote access to configuration, monitoring, and diagnostics reduces on-site effort and enables rapid response to faults.
• Replacement concepts: Hot-spare devices, standardized images, and on-site service contracts ensure that a defective device can be replaced within defined time windows.

Integration with WMS, MDE systems, or control software is typically achieved via standardized interfaces. The choice of connections — serial ports, USB, Ethernet, fieldbus — must be clarified in advance depending on peripheral devices such as barcode scanners, printers, or touchscreens.

What matters when making a selection?

When procuring IPCs, you should evaluate the following points:

• MTBF (Mean Time Between Failures): This metric provides information about statistical reliability, but is determined by the manufacturer using varying methodologies and is therefore only partially comparable.
• Lifecycle commitments: How long are spare parts and identical devices guaranteed to be supplied? Short lifecycles force frequent migration projects.
• Service contract and response time: On-site service with an agreed response time is often more important in time-critical environments than the device price itself.
• Thermal concept: Fanless devices require less maintenance but reach their limits under high computational loads. Fan-based systems require regular cleaning.
• Dependency on proprietary hardware: Highly vendor-specific solutions can become problematic in the event of supply shortages or product discontinuations. Standardizing on a small number of device types simplifies inventory management and reduces training effort.

Office PCs may function as a transitional solution in individual cases, but are generally not designed for continuous operation under industrial conditions and fail more frequently — with corresponding downstream costs.
