The Allen-Bradley 1756-ENBT Ethernet/IP Bridge Module is a ControlLogix Ethernet interface that resides in a 1756 I/O chassis to connect an Allen‑Bradley ControlLogix controller to an Ethernet network. It provides a single copper RJ45 10/100 Mbps port with auto‑negotiation, supporting EtherNet/IP communications and up to 64 TCP connections. This module enables EtherNet/IP communications between the ControlLogix controller, remote I/O, and external devices such as HMIs and SCADA systems over standard Ethernet. Three bi‑color LEDs on the module provide diagnostics for power, link, and activity status.
