Control Engineering Top 5 most read articles online, for May 25-31, covered HMI-historian integration, the Control Engineering salary and career survey, controller selection criteria, HMI-historian integration benefits, and platform-based tools overcoming the IIoT's complexity. Link to each article below.

1. HMI-historian integration

Put big data to work: Use the past to change the future with real-time input. Integrating human-machine interface (HMI) and historian software can produce hybrid screens comparing the past to the present to effectively change the future for the better. 

2. Control Engineering salary and career survey, 2015

Control Engineering research: While slightly less is expected for salary and significantly more for bonuses in 2015 compared to 2014, concerns about shortages of skilled workers remained highest on the list of challenges. 

3. Controller selection criteria

Selecting a controller for an industrial application can be increasingly difficult with all the options available. These 11 selection criteria can help when deciding among relays, timers, analog instruments, smart relays, programmable logic controllers (PLCs), and programmable automation controllers (PACs). See controller selection table. 

4. 7 benefits of integrating human-machine interfaces, historians

Human-machine interfaces (HMIs) and historians differ but need to be tightly integrated to provide company operations with optimal value. Big data has little value without analysis and access in real time. Seven application examples explain HMI-historian integration benefits, including troubleshooting, analysis, and regulatory compliance. 

5. Platform-based tools overcome Industrial Internet of Things complexity

Smarter, platform-based approaches can address the complexity challenges the Industrial Internet of Things (IIoT) brings to enable IIoT systems that are adaptive, scalable, secure and continually modified and maintained. 

The list was developed using CFE Media's web analytics for stories viewed on, May 25-31, for articles published within the last two months.
