Industrial Ethernet outsells fieldbus for the first time

摘要

INDUSTRIAL ETHERNET has, for the first time, overtaken traditional fieldbuses in terms of the number of new nodes installed in factory automation applications around the world, according to the latest in a series of annual surveys of the industrial networking market conducted by HMS Industrial Networks. During 2017, industrial Ethernet accounted for 52% of new installed nodes (up from 46% in 2016), while fieldbus nodes dropped from 48% to 42% of the market. EtherNet/IP is now the most widely installed network, with 15% of the market, followed by Profinet and Profibus, both on 12%. Wireless technologies held steady with a 6% market share.
