摘要

At least eight organizations represent seven Ethernet protocols targeting industrial networking applications. Here are updates about two Ethernet protocols: Ethernet-Powerlink and EtherNet/IP, Information on other industrial Ethernet protocols can be viewed in the "Online Extra" addition to this article at www.controleng.com. Marc Ostertag, vice president of B&R Industrial Automation, representing Ethernet-Powerlink, offers compelling reasons for using Ethernet for industrial automation. Ethernet is the most common network in IT; engineers are familiar with Ethernet, it offers transparent communication on all levels, it's an undisputed worldwide standard so it is "future-proof," it has compelling data rates, and offers a lot of software and many tools.
