Control Engineering Top 5 most read articles online, for Jan. 26-Feb. 1 covered object detection, integrating third-party systems with a DCS, high-performance HMIs, ROS-Industrial open source robotic programming, and learning PID loop tuning from an expert. Link to each article below.

1. Support-focused enterprise controls: Object detection

The ability to sense objects and trigger an application is the most overlooked fundamental of control design. Two common forms of object detection are presence detection and movement detection. 

2. Integrating third-party systems with a DCS

Several considerations need to be made when interfacing a distributed control system (DCS) to a third-party system, including the choice between using SCADA or peer-control solutions.

3. High-performance HMIs: Designs to improve operator effectiveness

Users and system designers consider how changing HMI strategy can help make operators better at their job and reduce those confused phone calls. 

4. Open-source robotic software platform, ROS-Industrial, augments efficiency, reach

ROS-Industrial, a group that provides open-source robotic software, expanded its influence in 2014 through companies and developers in the United States and Europe. The Linux-based software expects to expand to Microsoft platforms in 2015 and participate in an Amazon robotic picking challenge in May. 

5. Learning PID loop tuning from an expert

Hands-on experience helps accelerate the PID learning curve. 

The list was developed using CFE Media's web analytics for stories viewed on, January 26 to February 1, for articles published within the last two months.
