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.
Plant and operations managers need to be aware that their distributed control systems (DCSs) and programmable logic controllers (PLCs) could be obsolete and they should take appropriate steps to deal with the problem. Six immediate action items for an aging system are highlighted.
Automation pyramid part 6: The easiest way to understand the pyramid as a whole is to see how information moves from Level 1 to Level 5 and how to get value out of data analysis.
Cover Story: ROS-Industrial, an open-source factory automation software project, will celebrate its fifth anniversary in January 2017 by expanding into Asia, increasing visibility in a major robotic competition, and is looking to improve workplace efficiency and safety with its programming.
Most proportional-integral-derivative (PID) applications use digital controllers, though some still use analog. Digital control can offer additional process control system efficiencies.

Cover Story: Advanced robotic developments include improved designs for safety and specialized environments, collaborative applications, better integration with other systems, and augmented monitoring to reduce risk of downtime and lower maintenance costs. See photo gallery, links to five videos of robots.
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.
The automotive industry has made many technological and safety enhancements, which can be applied to other industries. See five advances and advice on traceability and data collection, upgrades, machine vision, robotics, and safety systems.
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.
Object-oriented programming (OOP) is about organizing and simplifying program elements in an optimal way by using objects, methods, and properties.
