1756-ENET Product Description Allen-Bradley 1756-ENET, also named ControlLogix Ethernet bridge module, is an EtherNet/IP communication module for ControlLogix PLC series. It is designed to establish industrial Ethernet network connection, supporting real-time I/O implicit messaging and explicit data transmission for legacy automation system upgrade.

This module delivers reliable network communication for industrial control tasks. The network communication supports rack optimized connection and direct connection setup. The network communication realizes bidirectional data exchange between PLC and field devices. Stable network communication completes real-time data transmission for distributed control systems.

The built-in data processing achieves steady signal transmission. The signal transmission provides 10BASE-T network access via AUI connector. The signal transmission supports scanner and adapter working modes. Accurate signal transmission ensures synchronous data interaction according to control logic.

Chassis plug-in structure brings convenient system expansion. System expansion can be directly inserted into ControlLogix rack. System expansion exchanges data with Logix5550 CPU via backplane bus. Flexible system expansion is widely used for old ControlLogix system spare replacement.

1756-ENET supports rack connection optimization and network fault diagnosis function, equipped with AUI port for Ethernet wiring. It has LED status indicators for network link and module health diagnosis. Widely applied in packaging machines, material handling equipment and traditional factory automation lines. This product is discontinued by Rockwell Automation, mainly supplied as industrial spare parts, complying with ControlLogix industrial control standards.
