Control Engineering hot topics, February 2017
Hot topics in Control Engineering, for February 2017, included stories about the Engineers’ Choice Award winners, safety instrumented systems, differences between PLCs and computers, matrix VFD technology, and multi-platform fluency. These are based on the top 10 most read articles online in Control Engineering
during February. Links to each article below.
The 30th annual Control Engineering Engineers’ Choice Awards shines a light on 28 categories of control, instrumentation, and automation products, revealing the best of those introduced in 2016 as chosen by you, Control Engineering’s print and digital audience.
The measurement part of a safety system tends to be the most troublesome. However, new technologies offer ways to overcome many common-cause problems.
Multivariable controllers can balance competing objectives. Process controllers that can juggle multiple process variables simultaneously are becoming more common and more powerful, but they can still be difficult to design and implement.
Critical industries, such as chemical, energy, transportation, and water/wastewater depend on supervisory control and data acquisition (SCADA) systems for daily operations. Strengthening weaknesses in these systems must be a priority and is a shared responsibility.
The Industrial Internet of Things (IIoT) has progressed from dream to hype to reality. Today, the basic deployment scenarios of the IIoT solutions we implement for our end user manufacturing customers.
On the surface, programmable logic controllers (PLCs) and computers are similar, but PLCs can perform discrete and continuous control functions that a computer can’t.
Controllers available for modern applications include programmable logic controllers (PLCs), programmable automation controllers (PACs), distributed control systems (DCS), industrial PCs (IPCs) or PC-based control, and embedded (board-level) controllers. What criteria should be used to choose among them and why?
Providing cost, space, and energy efficiency for VFD applications.
Users looking to select a variable frequency drive (VFD) need to consider their application, power source characteristics, and other safety and maintenance aspects to ensure that a production plant’s operations remain smooth with minimal downtime.
Being fluent in multiple platforms can be a helpful tool in the automation field for engineers and integrators and can give the engineer the ability to solve more problems and be a better, more rounded engineer.
The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, Feb. 1-28, for articles published within the last two months.
On Mondays, see the top 5 articles of the prior week. In January, see the hot topics for the year.
