The top 5 most read articles online, from July 15-21 for Control Engineering covered PLC programming languages, digitalization advantages, alarm management tips, operationalizing cybersecurity, and CNC developments. Links to each article below.

1. Other PLC programming languages

Ladder logic is commonly used in the U.S. for programmable logic controllers (PLCs), but other languages are better suited for some programming applications. See sample PLC code in five languages.

2. Digitalization advantages

Think Again: Major automation companies tout next-generation tools offering digitalization advantages, mobility and flexibility, for greater speed to higher profits.

3. 10 alarm management tips for the busy control engineer

Alarm management has been a great success for the process industry. Initial challenges have largely been met, but new challenges have emerged. Alarm management is most effective as an operations tool, not a safety tool.

4. Benefits of operationalizing cybersecurity

Operationalizing cybersecurity requires balancing protection and response with cyber attacks, which are not predictable, and trying to stay ahead of the people who are actively looking to cause problems.

5. CNC technology developments help engineers cut corners in all the right ways

Cover Story: Automation technologies continue convergence across platforms and computer numerical control (CNC) technology advances, along with faster control hardware and software, allow engineers to complete more accurate cuts in less time.

The list was developed using CFE Media’s web analytics for stories viewed on, July 15-21, for articles published within the last two months.
