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.
Stride to Redundancy

|Serial to Ethernet
Converters integrate serial port devices into industrial Ethernet networks, with two ports compatible with RS-232, RS-422 and RS-485. Two built-in Ethernet switch ports eliminate need for an additional switch to daisy chain ports or extend the network via the Ethernet line. Ethernet interface supports TCP Server, TCP Client, UDP, Real COM, RFC2217, Reverse Telnet, Pair Connection and Ethernet-Modem.
mGuard RS2000 and RS4000 provide defense-in-depth cybersecurity with all-in-one firewall, VPN and routing capability. With new metal housing, they operate in -20 to 60 °C range. Users can save a configuration on an SD card in one mGuard and insert that card into a new mGuard to duplicate settings. Configured with an SD card, the settings will remain, even if the SD card is removed.
