Top 5 Control Engineering articles, August 25-31: Future of the PLC, the first PLC, System Integrator Giants, more
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.
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.
The 2014 System Integrator Giants boast a $396 million increase in system integration revenue, a greater concern for the economy’s impact on the automation integrator market, and a strong belief in educational and mentoring programs for employees.
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.
Engineering and IT Insight: Good coding habits reduce errors, save time, and can help you become a better control system programmer. These simple habits may seem to add extra work, but they actually reduce the overall time to code and debug control programs.
