The Allen-Bradley 1756-ENBT Ethernet/IP Network Module is a ControlLogix Ethernet interface that bridges a Rockwell controller to an EtherNet/IP network, functioning as either the controller’s network interface or an adapter for 1756 I/O modules on Ethernet/IP. It supports 10/100 Mbps copper Ethernet and can handle up to 64 TCP connections and 128 CIP connections, enabling both I/O and messaging traffic across the backplane and network. Typical applications include linking a ControlLogix controller to remote I/O devices on EtherNet/IP, facilitating explicit and implicit data exchange, and using features like duplicate IP address detection to prevent network conflicts.
