1. Automation built for resiliency

Resilient automation products and practices are a necessity for most industrial applications using sensors, wiring, power distribution, controllers, networks, actuators and software integrated into an automation system.

2. The advantages of the IIoT

Industrial Internet of Things doesn’t replace, but works together with automation, human-machine interface (HMI), MES, ERP, enterprise manufacturing intelligence (EMI), and analytics, adding benefits.

3. Let IIoT do the dirty work: automating sewage treatment

Sewage treatment case study tracks early success, including accuracy and reliability.

4. Safety instrumented systems: Diversity in flow measurement

The designer should consider what problems should be avoided via diversity — use of a different approach or technology.

5. How to ensure OT cybersecurity

Despite advances, operational technology network cybersecurity still lags information technology cybersecurity.

The list was developed using CFE Media’s web analytics for stories viewed on, May 10-16, 2021, for articles published within the last two months.
