The Allen-Bradley 1756-EN2T is part of the ControlLogix family of communication modules. It is an EtherNet/IP (Ethernet Industrial Protocol) interface communication module. It supports regular messaging, real-time I/O messaging, and information exchange for applications such as real-time control, time synchronization, and motion. The 1756-EN2T also features the CIP security standard, which allows for the simultaneous transmission of security and control data as well as diagnostic 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 cable media. It supports 256 Logix and 128 TCP/IP communication connections. It can support up to eight axes for integrated motion over Ethernet /IP networks and consumes 1 A current at 1.5 volts DC. It has a maximum power consumption of 5.1 watts and a heat dissipation of 17.4 BTU/ hour. It can be installed in any slot in the ControlLogix chassis. For wiring, it uses an unshielded RJ45, Class 5 twisted pair cable connector to connect to the controller. To operate an Ethernet /IP network, parameters such as the IP address, subnet mask, and gateway are required. Must be defined. The 1756-EN2T bridge has a variety of functions, such as support for messaging, distributed I/O, and labeling. It encapsulates the message in the standard TCP/IP protocol. The ControlNet and DeviceNet network protocols allow it to share a common application layer. It does not require any scheduling or routing tables to store information. Additional features include protected mode, electronic keying, device-level ring networking, and parallel redundancy protocol networking support.
The 1756-EN2T is a ControlLogix communication adapter that supports the Ethernet I/P protocol. This module is a single slot module that can be installed into any slot in the ControlLogix chassis. It has one (1) RJ45 port for connection to the Ethernet network.
