Ethernet/IP DLR Fieldbus Coupler 750-366: Greater Flexibility Between Network & Plant

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. 

DLR is an Ethernet/IP protocol that is also used for managing single faults. DLR can manage, detect, and recover from single faults in a ring-based network.  The 750-366 uses DLR in conjunction with an Ethernet/IP network. The combination of Ethernet/IP and DLR allows the coupler to stay online and in operation, even in the event of a single fault failure. This allows for less interruption and more uptime in I/O failure since the system provides a means capable of handling commonplace failures.  

The 750-366 can be paired with any of WAGO’s 500+ I/O modules, creating application flexibility. This EtherNet/IP fieldbus coupler will support up to 250 I/O modules simultaneously when a bus extension module is used. Its fast boot-up time enables systems to get online quicker upon power-up. Firmware updates can now be accomplished using the coupler’s onboard Web-based Management System.

Features & Benefits:

  • Can be paired with any of WAGO’s 500+ I/O modules, creating application flexibility
  • Supports up to 250 I/O modules simultaneously when a bus extension module is used
  • Fast “boot-up” that enables systems to get on-line quicker upon “power up”
  • Firmware updates can be accomplished using the coupler’s onboard web-based Management System

Fieldbus couplers are an important part of plant system communication and function as a way of handling communication between devices on a network, and the WAGO 750-366 can help plants more efficiently manage data from plant-to-the-office. The new device uses DLR to create redundancy to reduce downtime when single fault failures occur.
