Control Engineering Top 5 most read articles online, for Sept. 15-21, covered using salt as an energy source, the competition for the first PLC, the future of PLCs, cascade control fundamentals, and a tutorial about how to write a process operations document. Link to each article below.
MIT study investigates power generation from the meeting of river water and seawater.
The race to develop the first programmable logic controllers was underway inside General Motors’ Hydra-Matic Transmission Division in Ypsilanti, Michigan, in 1970. Three finalists had very different architectures.
PLCs are evolving and continue to be the best option for a variety of industrial automation applications. Greater programming flexibility and ease, scalability, more memory, smaller sizes, very high-speed (Gigabit) Ethernet, and built-in wireless are among evolving programmable logic controller features.
Sometimes two controllers can do a better job of keeping one process variable where you want it.
Back to Basics: Describe your process to preserve the process engineer knowledge for the future. To program the process controller, programmable logic controller (PLC), or distributed control system (DCS), follow these steps and methodology.
