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.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
