as the basis for servodrive networking gained a major boost earlier this year
when the third-generation SERCOS and PROFInet working groups proposed plans for
future motion control networking. Both groups announced that
standard Ethernet technology would be utilized as the physical layer for next
generation versions –and compatible protocols for high, performance motion
control applications. At this year’s Hannover Fair, PROFIBUS International
(PI,www.profibus.com)announced the beginning of development work on a
high-performance, real-time solution for highly dynamic motion control
applications under PROFInet called Version 3.0 IRT. This proposed solution uses
standard Ethernet media, compatible protocols, and an ASIC that embeds both a
switch and the protocol to guarantee real-time, deterministic
Firewire Sparks New Interest- Of
the three networks available as a standard on PCs –Ethernet, USB, and FireWire
–the network that is least well-known is FireWire (or IEEE-1394).And in
industrial circles, with Ethernet gaining momentum for factory data
communications and I/O control, there is less awareness of a growing number of
FireWire-based control solutions. But that level of awareness may soon change.
The 1394 Trade Association, which oversees the standard and has a primary focus
on computer and consumer electronics applications, is working with a coalition
of industrial companies to eek a FireWire standard for machine control,
including motion, vision, and I/O.
Automated Fluid Filler Shuts
Off Down Time-
fluid packaging machine based on a new design enables users to change from one
size container to another in minutes, versus hours, or even days, with a
mechanical system. Beyond the obvious productivity gain and cost reduction
benefits, the quick change capability enables cosmetics companies and other
purveyors of product in fluid form to justify smaller production runs, thus they
can continue to meet customers ’supply demands while also minimizing
inventory.to read the rest

NASA and Boeing developed a huge, carbon composite cryogenic fuel tank for deep space missions, and started testing it last month. The 18-ft cryotank will enable heavy-lift launch vehicles to send both humans and robots into deep space.
