Links to each article below.

1. Pros and cons of autotuning control: Part 2

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

2. Integrating IIoT equipment into manufacturing systems

The Industrial Internet of Things (IIoT) equipment should be integrated even into older manufacturing systems to optimize facility and system operations. Think you’re using IIoT technologies? Are you adding sensors in 12 steps or 6 steps?

3. Ladder logic’s future role in automation

Nine considerations when selecting a programming language. Ladder logic is favored by manufacturers in discrete industries, but as technology and automation evolve, its usefulness compared to other IEC 61131-3 programming languages and PC programming depends on application complexity and other factors. 

4. AR and VR: A safe landing on the plant floor

Revolutionize factory visibility with augmented and virtual reality. Seven tips for leveraging functionalities are highlighted.

5. 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.
