U.S. IEC62026 Devicenet has become the international standard of the low pressure switch 3 equipment and control equipment controller device interface, and has been listed as European standards, is actually Asian and American equipment web standards. In October 2002, DeviceNet approved as a Chinese national standard GB/T18858.3-2002, and in 2003.4.1 up implementation. At present, Devicenet technology belong to open Devicenet manufacturers association ODVA organize all and promotion. ODVA worldwide have more than 300 famous automation equipment manufacturers such as Rockwell, the member (ABB, Omron, etc.). Our ODVA organization led by Shanghai electric science institute was established, which is now actively promote this technology.
