T-Series PLCs from Toshiba now have low-cost operator interface stations (OIS) that need no wiring or programming. Available in two models--OIS 10 and OIS 15--the interfaces have cables that plug directly into the PLC's RS232 port, from which they draw their power. All messages and other actions are saved in the PLC or register memory, eliminating the need for programming. The OIS 10 displays two lines of up to 16 characters per line, while the OIS 15 displays four lines of up to 16 characters per line. With either, messages are limited in length only by the available PLC memory and can consist of flashing alphanumeric alarms, embedded register values, bar graphs, or other information. The OIS 10 has six user-definable keys and two user-definable LEDs; the OIS 15 offers eight keys and four LEDs. Toshiba International, Product Code 4302.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
