The top 5 most read articles online, from Sept. 5-11 for Control Engineering, covered ladder logic, safer process facilities, stepper motors and closed-loop technology, small-scale automation projects, and SCADA cybersecurity. Links to each article below. 

1. Ladder logic 106: One shots

Different programmable logic controller (PLC) manufacturers use one shots to develop a scan that is exactly one scan in duration and can be generated from the rising or falling edge of the signal.

2. How to keep process facilities safe

Proper safety management can be taken to minimize risk.

3. Stepper motors use closed-loop technology for servo applications

Closed-loop stepper motors help deliver precision and efficiency to applications that require the performance of a servo motor. Learn about the characteristics and applications for servo motors and stepper motors.

4. Small-scale automation projects

How to get past time, money, and resource issues when executing small projects and specifying automation equipment and components.

5. SCADA cybersecurity in the age of the Internet of Things 

Supervisory control and data acquisition (SCADA) systems’ traditional role is changing as the Industrial Internet of Things (IIoT) continues to take a larger role. SCADA systems were not originally designed for cybersecurity and plants need to adjust to this new reality.

The list was developed using CFE Media's web analytics for stories viewed on, September 5-11, for articles published within the last two months.
