The top 5 most read articles online, from Oct. 8 to Nov. 7 for Control Engineering, covered the Engineers’ Choice finalists, PID velocity, PLC object-oriented programming benefits, scary automation on Halloween, and operating a three-phase motor. Also see what ranked 6-10 over the last month.
For a limited time, the official Engineers’ Choice ballot is open for voting for Control Engineering North American print and digital edition subscribers. Vote for the best Engineers’ Choice finalists of 116 entries across 28 categories.
Inside Process: Proportional-integral-derivative (PID) theory is best introduced as the familiar second order differential equation via the velocity form instead of the more traditional positional form.
Object-oriented programming (OOP) is about organizing and simplifying program elements in an optimal way by using objects, methods, and properties.
Automation is used in ghoulish and frightful ways by one particular sales manager on Halloween who is determined to satisfy his children’s urge and desire to scare. See video for more frights and scares.
There are several methods to operating a three-phase motor using single-phase power to make what would be an otherwise expensive and arduous process a little easier.

As an online-only feature, we’re featuring the stories that finished 6-10 over the past month.
PLCopen has released coding guidelines designed to help provide industrial control programming solutions for programmable logic controllers (PLCs) and was created by members from different companies as well as educational institutions.
Inside Process: Like other types of valves butterfly valves interrupt product flow within processes. Typically used in pharmaceutical, chemical, and food industries, they have generally replaced ball valves due to lower cost and ease of installation.
For automation, return on investment (ROI) is more important than total cost of ownership (TCO). When making a capital investment in automation, companies need to determine value based on the solution’s impact on facility performance and its workforce. Also consider cost of downtime and services.
Cover Story: New tools beyond the spreadsheet are needed to empower process engineers so they can derive insights from the data that is being transmitted.
There are many level measuring techniques, however they need to be the right fit for the application. See the three key constraints to measuring solids in tanks and vessels.
