Top 5 Control Engineering articles, Sept. 1-7: The first PLC, wireless propagation fundamentals, future of the PLC, more
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.
Industrial wireless tutorials: Understanding wireless propagation fundamentals will help you understand what can happen to a wireless signal and how that can influence wireless signal reliability. See 6 diagrams to illustrate wireless propagation. Learn the 4 results of multipath.
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.
Engineering future: Ambition to change the world is essential as automation spreads into areas beyond industrial applications. See three key technology advances expected by 2020 and a sampling of those advancements today, including mobile robotics, as explained by Control Engineering China.
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.
