Top 5 Control Engineering articles September 12-18: PID control, ladder logic, system integration and packaging, more
The top 5 most read articles online, from Sept. 12-18 for Control Engineering, covered PID control and loop tuning fundamentals, ladder logic, system integration improves packaging operation, tablet-based augmented reality, and improving plant and energy efficiency.
PID loop tuning may not be a hard science, but it’s not magic either. Here are some tuning tips that work.
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.
Cover Story: System integrator upgrades a cherry packaging operation at Prima Frutta, for a 50% production increase, using Ethernet, wireless, and mobility technologies, along with extensive planning and simulation.
Video: sensors on critical pumps can feed a system to help technicians or operators identify when failures are pending and improve energy efficiency. A major U.S. refinery will host a pilot pump diagnostic project, similar to an NIWeek 2016 stage demonstration held on Aug. 2.
System integrator Stone Technologies addresses data management and energy savings, higher quality, and easier changeovers with a modern distributed control system (DCS) for a glass bottle manufacturer that monitors more than 1,000 data tags and 2,600 detailed and manageable alarms.
