Why can't we have more exciting graphics?
HMIs can have spectacular graphics. Why shouldn't we use them?
Dear Control Engineering: I was reading the article Gray Backgrounds for DCS Operating Displays. Why is operator response so important? Aren’t most problems caused by the equipment?
The Abnormal Situation Management Consortium says that people factors account for 42% of incidents, which is why the group spends so much time on operator training and how individuals interface with the control system. (If you’re curious, equipment factors account for 36% of incidents, and process factors for only 22%.)
If an operator has to look at an HMI screen and ask him or herself what that blinking red thing means, it means that the operator is not adequately trained, or that the HMI graphic is not consistent in its use of color. Any time spent gathering thoughts and interpreting graphics simply slows the response and allows the problem to go on longer, potentially escalating in scale and damage. Worse yet, an operator may take the wrong action if he or she doesn't understand immediately what the display is trying to say. Consistency is critical.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
