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
EN50155-certified EKI-6528TPI industrial switch with IP40 protection and M12 connectors provides four PoE ports that support IEEE 802.3af and provide up to 15.4 W per port. Under no-power condition, an auto bypass function ensures the Ethernet signal connection through internal circuitry.
|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.
|Something for Everyone
Stratix 8300 Layer 3 managed switch provides VLAN and subnet routing capability using Cisco Catalyst operating system, feature set and user interface, offering IT the same programming and configuration tools they already use. The switches integrate into Integrated Architecture system, making plant-floor engineers feel at home. Inter-VLAN routing and advanced routing protocols allow users to integrate multiple cell zones and connect with manufacturing and enterprise-level networks.
|Manages a Lot
EISK8M-100T managed 10/100 Mbps Ethernet switch with eight copper ports provides SNMP managed applications, supports authentication, IP address assignment, trunking, port mirroring, VLAN, port forwarding, QoS, programmable fault relay, cable redundancy, rate limiting, port security and Internet group management protocol (IGMP) snooping.
|In the Coupler
Integrated Ethernet switch in machine-mount Speedway 767-2301 programmable fieldbus coupler ties IP67 components to Ethernet. It supports EtherNet/IP and Modbus TCP, and the Ethernet switch synchronizes harsh-environment machinery and higher-level control systems without additional components.
|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.
