Allen-Bradley 1756-ENBT Ethernet Bridge Module

The Allen-Bradley 1756-ENBT Ethernet Bridge Module is an EtherNet/IP interface card for Rockwell Automation's ControlLogix platform, designed to add network connectivity to a 1756 backplane chassis and enable a ControlLogix system to exchange data with enterprise networks. It occupies a single slot in a ControlLogix chassis and provides a 10/100 Mbps RJ-45 Ethernet port for standard EtherNet/IP communications, enabling CIP messaging between the controller, remote I/O devices, HMI panels, and SCADA systems over an Ethernet network. As a member of the 1756 ControlLogix family, the ENBT is powered from the backplane and supports Rockwell's EtherNet/IP stack and CIP protocols for both explicit and implicit messaging across standard Ethernet networks. Typical applications include linking a ControlLogix controller to PLCs, HMIs, data historians, or MES/SCADA systems to support real-time data exchange, remote diagnostics, and distributed control on the factory floor.
