1. Top 50 Automation Companies of 2017: Digitalization takes over
Maintaining the top spot, the storm surge of digital transformation, driven by the IIoT, cloud computing, advanced analytics and the push to managed services, continues to transform how the Top 50 do business. Read more.

2. Best practices for PID
PID control is used in more than 99% of the loops for chemical, pharmaceutical, and food and beverage production. The opening challenge with PID control is recognizing the effect of PID form, structure and tuning units. Read more.

3. Understanding P, I and D
It is important to understand what the proportional, integral and derivative terms do within the PID controller. That understanding is essential to choose appropriate action, troubleshoot controllers, choose appropriate modifications, or set up advanced controllers. Read more.

4. Live from Automation Fair 2018
The editors of Control were on-site at Automation Fair 2018 to bring you the latest breaking news and trends from the event. Read more.

5. Compressor surge control: Deeper understanding, simulation can eliminate instabilities
We tend to rely on companies specializing in surge control to protect our plants, but what happens if something is not quite right in the middle of night, causing a surging fright and piping to take flight? Read more.

6. How PLCs are hacked
Securing programmable logic controllers (PLCs) was earlier not considered a priority; these components are built to run in isolation and in an air-gapped environment. This is no longer the case in many circumstances, due to the increase in real-time and remote data collection, as well as the increase in remote monitoring and efficient maintenance. Read more.

7. Prevent pressure transmitter problems
A measurement is only as good as its installation. Here, Hunter Vegas, Daniel Warren and Greg McMillan offer what they think is important for how to make sure that smart transmitter installation doesn’t limit performance or create maintenance and reliability issues. Read more.

8. Wireless expands availability through innovation, simplification and acceptance
Wireless may not get all the attention, but digitalization wouldn't be as powerful without wireless technologies supporting it 24/7/365 from behind the scenes. Read more.

9. OPC UA accelerates with time-sensitive networking
The OPC Foundation announced Nov. 5 that it's launching a new setup to identify OPC UA and related time-sensitive networking (TSN)-harmonization needs and extends OPC Foundation standards and specifications. Read more.

10. What isn't understood about control system cyber security can lead to catastrophic failures
Joe Weiss discusses the progress made on IT and OT security, while also urging that we not forget the other challenges in cybersecurity that have yet to be addressed. Read more.
