Is Office Ethernet Hardware Tough Enough for Industrial Use?
Considerations include operating temperature, humidity, operating voltage, redundancy, vibration, and more. See comparison table.
In selecting physical media, data links and industrial network hardware for industrial Ethernet, it is important to ensure optimal performance, ease of maintenance, and long-term reliability. Rugged industrial Ethernet products have been designed to network in tough environments, to support industrial protocols being transmitted across these networks, and accommodate industrial environments.
When specifying industrial-grade network components, consider reliability and risk-related issues, such as mean time between failure (MTBF).
Designs of industrial Ethernet products provide the same lifespan as other automation components—10 to 30 years or more. Typical commercial grade products are built to achieve a 5-year average lifespan.
Industrial Ethernet hardware devices are usually DIN-rail mounted or bolted directly onto the machines that receive transmitted data.
In addition, equipment typically occupies less space to allow greater density within a control panel.
Industrial Ethernet devices rely on passive heat dissipation and may be available in dustproof and waterproof housings.
Redundant power, redundant media paths and even redundant devices can help assure 24/7 uptime.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
