Nothing but Growth for Ethernet

Managed Switches Replace Hubs, Plain Vanilla Ethernet Remains a Favorite Flavor

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.

AutomationDirect's managed Ethernet switches 

Stride to Redundancy   
Stride industrial-grade, managed Ethernet switches with redundant power inputs with surge and spike protection and auto-crossover have real-time ring technology for recovery of all redundancy options on the switch. Most models have multiple 10/100BaseT, RJ45 Ethernet ports; others include ST- or SC-type fiberoptic connections.

 B&B Electronics' Elinx ESW100 unmanaged industrial Ethernet switches I See LC   
Elinx ESW100 unmanaged industrial Ethernet switches have LC small-form-factor fiber connectors and are panel-mountable. Five-port ESW105 and eight-port ESW108 have either all copper ports, or users can replace one copper port with an LC multi- or single-mode fiber port. Communication range is 2 km for multi-mode fiber and 20 km for single-mode.

 RS-232, RS-422 and RS-485 converters 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.
