Schneider Automation, Hirschmann to develop Ethernet solutions
Two developers often are better than one. To deliver better Ethernet solutions, Schneider Automation (North Andover, Mass.) and Richard Hirschmann GmbH & Co. (Neckartenzlingen, Germany) recently formed a long-term, strategic partnership. The two companies signed a memo of understanding at the Schneider Electric exhibit during National Manufacturing Week (NMW).
Network hits and misses
现在主要工业网络的一个列表d the near future reads like a top hits list from the past. According to the Control Engineering 1999 Industrial Networking survey, winning choices are tried-and-true strategies such as Ethernet, EIA-232 (formerly RS-232), and 4-20 mA. This bias toward the old is balanced, however, by a growing acceptance of digital networks and distribu...

Connect and be counted
Control Engineering wants to know what networks you use in your automation applications. In December 1998, we mailed an Industrial Networking survey to a 10% sample of our readers. If you received the survey, please take a few minutes to complete it and send it back. Other readers that want to participate can complete the survey on our web site at www.
The Ethernet wars
Profibus vs. FOUNDATION fieldbus; ControlNet vs. Interbus; DeviceNet vs. SDS; Seriplex vs. AS-Interface—the bus wars continue to rage. But a new challenger has changed the battle.Ethernet, a standard in business networking since the mid-1980s, is touted by vendors and users alike as a contender for industrial applications.
National committees torpedo IEC 61158 in close vote
