The Rockwell Automation ControlLogix 1756-EN2xx High Capacity EtherNet/IP Bridge Modules are the ideal solution for EtherNet/IP communication in demanding applications. The modules supports all the functionality of the 1756-ENBT (bridging, messaging, real-time control of I/O, and peer-to-peer interlocking over EtherNet/IP) with two times the capacity. They are equipped with a USB port which allows easy access for configuration of the module as well as access to other parts of the control system. Thumbwheel switches located on top of the module enable users to quickly set up an IP address to minimize configuration time. Like the 1756-ENBT, when used in conjunction with other ControlLogix bridge modules in a gateway system, they can route messages between EtherNet/IP and other NetLinx networks without the intervention of a ControlLogix controller.
