The new Allen-Bradley CompactLogix controller from Rockwell Automation (www.rockwellautomation.com) offers a SERCOS interface, EtherNet/IP connectivity and a powerful processor. Controlling up to four axes of motion, the 1768-L43 is designed for applications requiring speed, motion synchronization and information-sharing capabilities in a small, modular footprint. It combines motion and sequential control into a single, integrated multitasking platform and supports a full range of networks including DeviceNet, ControlNet and EtherNet/IP. The controller uses the same Logix control engine, motion, networking technology and communications services as the A-B ControlLogix and SoftLogix controllers.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather.

Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
