The Allen-Bradley 1756-EN2T is a part of the ControlLogix Communication Module series. It is an EtherNet/IP (Ethernet Industrial Protocol) interface communication module. It supports general messaging, real-time I/O messaging, and information exchange for applications like Real-Time Control, Time Synchronization, and Motion. The 1756-EN2T also has the CIP safety standard by allowing simultaneous transfer of safety and control data and diagnostics information. It uses advanced communication chips and physical media.

The 1756-EN2T supports 10 to 100 Mbps EtherNet/IP communication rates and uses Twisted pair copper media. It supports 256 Logix and 128 TCP/IP communication connections. It can support a maximum of 8 axes for integrated motion on the Ethernet/IP Network and draws 1 A current at 5.1 Volts DC. It has a maximum power dissipation of 5.1 Watts and thermal dissipation of 17.4 BTU/hour. It can be installed in any slot in the ControlLogix Chassis. For wiring, it uses unshielded RJ45, category 5, twisted-pair cable connectors to interface with the controller.

The 1756-EN2T bridge has various functions like providing support for messaging, distributed I/O, and tags. It encapsulates messages within standard TCP/IP protocol. ControlNet and DeviceNet network protocols allow it to share a common application layer. It does not require any scheduling or routing table to store information. Other features include a protected mode, an electronic keying, a device level ring network, and a parallel redundancy protocol network support.

The 1756-EN2T is a ControlLogix Communication adapter that supports Ethernet I/P protocol. This module is a single slot module which may be installed to any slot of a ControlLogix chassis. It has One (1) RJ45 port that is used to interface with Ethernet network.

This module is capable of being connected to a network with linear topology and it supports 10/100 Mbps communication rate. It is compatible with any ControlLogix Chassis such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17 and ControlLogix Power supply such as 1756-PA72, 1756-PA75, 1756-PB72, 1756-PB75, 1756-PC75, 1756-PH75.
