The latest TwinCAT product merges PC-based PLC and motion control with next-generation Ethernet. TwinCAT 2.10 can scan hardware through Beckhoff, Profibus, CANopen, DeviceNet, SERCOS, real-time Ethernet and Lightbus high speed, deterministic EtherCAT. It compares networks to system configurations, identifying what hardware is physically present, making for faster and easier diagnostics.
TwinCAT has always been able to synchronize multiple deterministic networks and offered support for multiple fieldbus networks simultaneously. The 2.10 version now does the same thing for EtherCAT-networked devices, so high-speed EtherCAT devices can be added into systems and use other fieldbuses and I/O devices at the same time. It also lets systems use different update rates for different drives, meaning the CPU can now run control loops only as often as necessary, so all drive control loops no longer have to run at the fastest rate required. TwinCAT 2.10 allows full remote target systems programming for Beckhoff BC, BX, CX and PC controllers, with communication via TCP/IP, HTTP and serial connections. TwinCAT software allows open, PC hardware to replace the conventional PLCs, NC/CNC controllers and operating devices.
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. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
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.
