Here are some key features of the 1756-ENBT module:

EtherNet/IP Communication: The module supports EtherNet/IP, an open industrial Ethernet network protocol widely used in automation and control systems.

mmunication Physical Medium: It supports 10/100 Mbps auto-negotiation for the physical layer and can connect using either a copper cable (RJ-45 connector) or a fiber optic cable (SC connector) for long-distance communication.

Device-Level Ring (DLR) Support: The module supports Device-Level Ring, which provides high network availability and fault tolerance by creating a redundant ring of network devices.

Dual Ethernet Ports: The module has two Ethernet ports, allowing for network redundancy or separate network connections for different purposes.

Embedded Web Server: The module includes an embedded web server that allows users to configure and diagnose the module using a web browser.

The 1756-ENBT module is widely used in industrial automation applications where EtherNet/IP connectivity is required. It offers reliable and high-performance networking capabilities for seamless integration of ControlLogix PLCs into an EtherNet/IP infrastructure.
