VCA and WAGO are offering the “newest generation” EtherNet/IP Device Level Ring (“DLR”) Fieldbus Coupler 750-366 which updates the previously released 750-363. Fieldbus couplers are common in industrial applications because they create communication links between networks and devices. These devices are often included in a tiered system of data transmission for more efficient use of bandwidth, and the 750-366 is specifically designed to support DLR.
