PI International conducted an extensive, highly instrumented study of different automotive plants, and looked at what happens during a production pause. The conclusion from that study is that up to 30% savings are achievable using Ethernet protocols such as PROFIenergy. That is a significant impact.
This technology is an excellent example of how intelligent algorithms and network communication will enable better energe management in the future. As part of the application software on machines, energy solutions such as CIP Energy, PROFIenergy and sercos energy (to name a few) are going to provide tools that make it relatively easy to implement energy saving strategies on the machine level. Will be interesting to see the adoption rate for this technology moving ahead.
Yes, it's a good idea, Naperlou. We may end up winning the energy challenge -- in many industries -- through inventive conservation. Just 10 short years ago, energy consumption wasn't really on anyone's radar. With an intense focus on energy, we may make some real progress.
Rob and Al, I thought from the title that this might be something different. As it is, it is very interesting. As Rob mentions, this is a lot like the automobile with an autoshutoff/start engine. In the computer world, it is a lot like the ARM processor. This processor architecture is unique in that parts of the CPU can be shut down to the point that only those parts essential to the current operation powered. This is why ARM has won in mobile device/battery run applications. The CPU can go into a state where there is just enough circuitry powered to respond to an external signal (or interrupt). All of this is under programmer control. In the same way, these power management objects mentioned in the article allow detailed control of power usage by machinery. The parallels are very interesting. Next stop, the power generation grid.
Rob, You're right. The energy focus is now here to stay. But the possibilities going forward with this technology will get even more sophisticated because of the ability to implement energy algorithms that save energy within the production cycle itself as well.
Nice story, Al. This is the plant version of the car that shuts down when it's at a red light. It wasn't too many years ago that plants didn't monitor energy consumption or even care about the subject. That certainly changed for a few short years.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
