WAGO Corp.'s high-speed 750-881 ETHERNET 2.0
Programmable Fieldbus Controller processes 1,000
Î¼S. The first from WAGO's upcoming ETHERNET 2.0 line, 750-881
provides significant amounts of memory for PLC programs and Web applications,
as well as an integrated dual-port Ethernet Switch. To keep pace, independent
Ethernet ports respond in 1ms, transmitting real-time information to production and enterprise
750-881 PFC interfaces with standard network protocols, including unique
support for both EtherNet I/P and MODBUS TCP. The Ethernet switch streamlines
costs and system footprint by facilitating a line topology for fieldbus wiring,
eliminating additional switches and hubs. An onboard DIP switch configures the
last octet of IP address/assignment, expediting commissioning.
Keys to the 750-881's high-frequency processing are a 32-bit CPU and 1Mbyte
of program memory. A 2Mbyte Fast File System supervises
both a Web-Based Management System and substantial data logging. E-mail
capability (updates/alarms) is also provided for authorized personnel. 750-881's
standard CoDeSys V2 programming environment is IEC 61131 compatible and features all
five programming languages. The PFC supports up to 250 I/O modules
and allows users to tailor solutions from the 400+ analog, digital and
specialty modules in the WAGO-I/O-SYSTEM.
750-881's new housing design departs from WAGO's traditional architecture. The slotted
housing optimizes heat dissipation while maintaining a 0 to 55C operating
temperature range and IP20 rating. Certifications include UL
508, cUL, GL and CE.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
