PLCs have steadily increased their responsibility, at first replacing relay systems, then taking over process control and stepping in for motion control, according to Greg Meinert, PLC business manager for Siemens Energy and Automation. Now, by adding safety, PLCs are collapsing everything down to a single platform, Meinert says, reducing engineering, start-up and maintenance. Fail-safe CPUs execute both standard programs and safety functions. They also eliminate a need for separate safety PLCs.

In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
