Our most recent survey of the Industrial Networking audience identified some network switch use and application trends.
We learned that almost 70% of respondents said their speed requirement was 100 Mbps, while nearly all the rest said they needed Gigabit speed or faster. In addition, 61% of respondents connect with both copper and fiberoptic cables, while 31% use only copper and 8% use only fiberoptics. Further, 33% indicated their Ethernet switches are Power over Ethernet (PoE)-enabled.

“We also see an increased need for Gigabit Ethernet, and the ability to mix copper and fiber connectivity on a single device,” says Diane Davis, director of Ethernet networking at Red Lion Controls. “The need for higher (Gigabit) speed is largely being driven by the use of cameras for security throughout industrial applications. Cameras and displays, in turn, are driving an increasing interest in Power-over-Ethernet.”
Industrial automation has embraced Ethernet and IP networking, and adoption of these technologies is growing, states Paul Wacker, product marketing manager at Moxa. “However, there’s still a huge installed base of devices and equipment with only serial (i.e., Modbus) connectivity,” Walker says. “In addition, there still are many manufacturers that don’t have the resources or expertise to add Ethernet to their products. Industrial Ethernet Gateways allow these serial devices to be connected to Ethernet, with built-in protocol conversion between EtherNet/IP and legacy protocols like Modbus RTU.”

The switches are available with six, 10 and 20 fixed-port configurations, and include IEEE-1588 time synchronization, QoS (prioritization) and Resilient Ethernet Protocol (REP).
EKI-3000 light-industrial, unmanaged switches are five and eight port Ethernet switches in 10/100 and Gigabit versions. Priority ports prioritize the traffic, and delay the less immediately necessary data. Smart diagnostic functions help discover a fault on the system without painstaking port analysis. Advanced power saving functions save up to 60% consumption by shutting down ports that have no link, and budgeting power based on the length of the Ethernet cable according to the IEEE 802.3az Energy Efficient Standard.
