It could also be a situation where size and packaging of the industrial PC are important, depending on where it's to be deployed, he explains. Many variables must be considered, and some will be more important to the end user than others. "Overall, the best feature is reliability — knowing that your industrial PC can be counted on for long-term operation," says Boutilier.
Charles Chen, embedded business development manager at Moxa Americas, agrees that reliability is the key. "An industrial computer is being used in a 24-7, mission-critical environment, with no down time, and a rugged and solidly designed computer becomes the most significant feature to have over programmability , performance or functionality," he says.
"Only picking one feature is tough, but I would say the availability of rugged mass storage devices, such as solid-state hard drives, is the most important feature to look for in an industrial computer," says Bjoern Falke, product marketing senior specialist, automation, Phoenix Contact. "These are designed to withstand challenges such a shock or vibration in an industrial environment. In the past, these solid-state drives were not available in the large sizes being offered today. In addition, the price of these drives has come down to a point where it makes them suitable and affordable to use in industrial PCs."
Corey McAtee, product manager at Beckhoff Automation, believes scalability is key. "When engineers are concerned with finding that controller sweet spot and balance performance with budget, it's invaluable to have a deep portfolio of controllers to choose from," he says. "Of course, that bull's-eye isn't going to stay put forever, so it's equally important to have the ability to move one way or the other over time as applications evolve and new markets are entered."
