The top 5 most read articles online, from Sept. 3-9 for Control Engineering covered autotuning, ladder logic, wireless IIoT gateway design, and LTE networks. Links to each article below.

1. Pros and cons of autotuning—the big story

The historic challenges of single-loop tuning, the limited success of autotuning, and the modern difficulties of model-based control share the same root cause.

2. Ladder Logic 306: Simulation

Using simulation for ladder logic allows users to test advanced situations that otherwise wouldn’t be possible, reducing potential costs and hazards for users.

3. Design a wireless IIoT gateway with open-source tools

Wireless: Software-defined radio (SDR) hardware and open-source programming software provides an alternative to proprietary wireless communications systems, helping improve Industrial Internet of Things (IIoT) networks.

4. Pros and cons of autotuning control: Part 1

Proportional-integral-derivative (PID) controllers that can automatically select their own tuning parameters sound good but face challenges.

5. Four reasons why LTE networks are not IIoT-ready 

As well as four reasons why kinetic mesh is a better broadband solution for the manufacturing industry.

The list was developed using CFE Media’s web analytics for stories viewed on, Sept. 3-9, for articles published within the last two months.
