The top 5 most read articles online, from November 29 to December 5, 2021, for Control Engineering covered APC limits and targets, embedded systems, Engineers’ Choice finalists, IIoT and controllers and COVID-19 testing. Links to each article below.

1. Understanding APC limits and targets

Process automation and optimization need to use automated multivariable control so it evolves into an industry core-competency, providing low cost, low maintenance and high agility with long life-cycle technology instead of manual multivariable control. Understand limits and targets of advanced process control.

2. Event-driven applications for embedded systems: Summary of PDF

C code is provided and explained for creating event-driven applications for embedded systems, and simulating a task-manager application.

3. 2022 Engineers’ Choice Finalists: Vote now!

The official ballot is open for voting for Control Engineering North American print and digital edition subscribers, for a limited time. Cast your vote online at

4. How is IIoT changing industrial controller use, selection?

How are programmable logic controllers (PLCs) and industrial PCs (IPCs), embedded controllers, programmable automation controllers (PACs), smart input/output (I/O) modules, other logic devices and related software helping Industrial Internet of Things (IIoT) promises envisioned? A webcast investigates.

5. COVID-19 antigen testing method offers fast, accurate results

An antigen-based COVID-19 detection method developed in a Northwestern University laboratory demonstrated 100% accuracy in a blind test in five or fewer minutes from swab to signal.

The list was developed using CFE Media’s web analytics for stories viewed on, Nov. 29 to Dec. 5, 2021, for articles published within the last two months.
