About 23% of the 31.3 million industrial networked nodes in 2011 were based on Ethernet or an Ethernet variant, reports John Morse, senior analyst at IMS Research.
IMS's 2012 World Market for Industrial Ethernet report says the remaining nodes use longstanding fieldbus technologies.
By 2015, the report projects, 26% of 45 million nodes will be Ethernet-based. Morse noted the installed strength of Ethernet TCP/IP, the "standard" form of Ethernet. For many users, the non-deterministic nature of this technology is not a problem. IMS estimated that Ethernet TCP/IP accounted for 43% of new nodes connected in 2010, and would decrease slightly to 40% in 2015.
IMS projects that Gigabit Ethernet will increase its share of the market by only about 0.3% over the next five years. IMS Research believes that, although many devices now have Gigabit Ethernet available at the port, it is only occasionally used. It is employed where a backbone is installed, but at the machine-level, 10/100Base-T over copper is more common.
At the component level, the adoption of managed switches will grow at a faster rate, superseding the market for hubs, which has all but disappeared.
