Rugged Computing: The Strategic Backbone of Industrial Automation
In today’s industrial automation landscape, digital transformation drives every operation. However, standard computing devices often fail in harsh industrial settings. Rugged computing has therefore evolved from a niche military technology into a core industrial automation necessity. This shift represents a strategic upgrade for any organization relying on control systems like PLC and DCS in demanding environments.
The Critical Role of Hardware in Industrial Automation
Industrial automation depends on reliable hardware performing in extreme conditions. Consumer and commercial devices frequently malfunction when exposed to vibration, dust, or temperature extremes. These failures directly impact production lines and control systems. Consequently, selecting purpose-built rugged computers becomes an operational imperative for manufacturing and process industries.
Understanding Device Categories for Industrial Use
Industrial organizations typically evaluate three device categories:
- Consumer Devices: Designed for personal use with limited durability
- Commercial Grade: Offer enterprise security but lack environmental protection
- Rugged Computers: Engineered specifically for harsh industrial environments
According to MarketsandMarkets, the rugged industrial computers market will reach $7.2 billion by 2027. This growth reflects increasing recognition that standard devices cannot withstand factory automation challenges.
Industrial Applications of Rugged Computing
Rugged computers serve critical functions across industrial automation sectors:
- Manufacturing: PLC programming and HMI interfaces on factory floors
- Process Industries: DCS monitoring in chemical and pharmaceutical plants
- Utilities: SCADA system maintenance in remote locations
- Logistics: Automated material handling system control
As World of PLC experts note, “Rugged tablets have become indispensable for control systems maintenance in environments where standard laptops would fail within weeks.”
The True Cost of Device Failure in Automation
Deploying non-rugged devices in industrial settings creates substantial hidden costs. A 2024 IEEE study revealed that device failure in manufacturing environments causes average productivity losses of $5,600 per incident. Moreover, these failures jeopardize control systems integrity and create safety hazards. Organizations therefore must calculate total cost of ownership rather than just initial purchase price.
Why Commercial Devices Underperform in Industrial Settings
Commercial laptops and tablets lack essential rugged specifications. They typically miss IP ratings for dust and water resistance. Additionally, they cannot withstand extended temperature ranges or constant vibration. As a result, commercial devices experience 3x higher failure rates in industrial environments according to Statista data. This reliability gap makes them unsuitable for critical automation tasks.
The Evolution of Modern Rugged Computers
Today’s rugged computers combine durability with high performance. Modern units feature:
- Full-sealed IP65-rated enclosures
- Extended temperature tolerance (-20°C to 60°C)
- Shock-resistant solid-state drives
- Sunlight-readable displays
These advancements ensure reliable operation alongside PLCs and other control equipment in challenging industrial settings.
Identifying Rugged Requirements in Your Organization
Most industrial companies have unidentified rugged use cases. Consider these scenarios:
- Technicians accessing PLC programs in dusty environments
- Engineers monitoring DCS operations in temperature-controlled rooms
- Maintenance teams using HMIs in high-vibration areas
World of PLC recommends conducting an environmental assessment before selecting industrial computers. This proactive approach prevents costly device failures and production interruptions.
Practical Implementation: Rugged Computing Case Studies
Automotive Manufacturing Solution:
A major automotive manufacturer deployed rugged tablets for PLC troubleshooting on assembly lines. This reduced device replacement costs by 67% and eliminated production stoppages previously caused by standard laptop failures.
Food Processing Application:
A food processing plant implemented rugged computers for DCS monitoring in high-moisture areas. The IP67-rated systems withstood daily washdowns while maintaining reliable control systems operation.
Strategic Integration for Long-Term Value
Rugged computing represents a strategic investment rather than just a hardware purchase. Properly implemented rugged systems deliver:
- Higher production line availability
- Reduced maintenance costs
- Enhanced worker safety
- Better return on automation investments
Industrial leaders should view rugged computers as essential components of their automation infrastructure.

Frequently Asked Questions
What IP rating is sufficient for factory floor applications?
Most industrial environments require at least IP54 for dust and water resistance. However, food processing or outdoor applications typically need IP65 or higher.
Can rugged computers run standard PLC programming software?
Yes, modern rugged computers run all major industrial software including Siemens TIA Portal, Rockwell Studio 5000, and Schneider Electric EcoStruxure.
How do rugged computers enhance control systems reliability?
By providing stable operating platforms in harsh conditions, rugged computers prevent unexpected shutdowns and maintain consistent communication with PLCs, DCS, and other control equipment.
