Allen-Bradley 1756-EN2T Ethernet Interface Module

The Allen-Bradley 1756-EN2T is a ControlLogix Ethernet/IP bridge module that provides the system’s Ethernet interface, enabling a ControlLogix rack to communicate with an Ethernet/IP plant network. It is a two-port module that supports 10/100 Mbps copper Ethernet (RJ45) and can handle up to 128 TCP connections, supporting multiple concurrent clients and services. As a member of the 1756 EtherNet/IP module family, it integrates with standard ControlLogix I/O and network configurations to extend PLC communications beyond the backplane. Typical uses include linking a ControlLogix processor with HMI, SCADA, and remote I/O devices across a plant network.
