The top 5 most read articles online, from June 21-27, 2021, for Control Engineering covered PLC benefits, HMI and SCADA design, six calibration tips, process control systems and cybersecurity’s past. Links to each article below.

1. The PLC remains stronger than ever

The programmable logic controller (PLC) has been declared dead many times, but it continues to thrive even in the Industry 4.0 era.

2. When designing HMI/SCADA, consider many factors

User abilities, skill levels, future plans, needs of stakeholders, and other items should be explored. See a system integrator’s advice and seven SCADA system integration/design questions to ask.

3. Six things automation and control engineers need to know about calibration

Cover Story: Reasons for calibration include new instruments, repairs or modifications or scheduled care. Learn details about calibration’s impact on preventive maintenance, schedules, documentation and more.

4. Keep process control systems connected with industrial network strategies

Traditional distributed control system (DCS) and supervisory control and data acquisition (SCADA) systems designs can be improved with industrial digital transformation. Seek industrial interoperability, modularity, conformity to standards, including security standards, scalability and portability.

5. Looking into the cybersecurity future through the past

The past informs the present when it comes to cybersecurity and what we once thought of as fanciful is becoming a reality. What people are willing to do will inform our future.
