1756-EN2TR
Allen Bradley 1756-EN2TR is part of the ControlLogix communication module family. It is an Ethernet/IP (Ethernet Industrial Protocol) dual port 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-EN2TR also allows for the simultaneous transmission of security and control data as well as diagnostic information, thus complying with CIP security standards. It uses advanced communication chips and physical media. The 756-EN2TR module has a 10 to 100 Mbps Ethernet/IP communication rate and uses dual copper cables. It supports 256 Logix and 128 TCP/IP communication connections. It can support up to 8 axes for integrated motion on Ethernet/IP networks and consumes 1 A of current at 1.5V DC. Its maximum power consumption is 5.1 W and thermal dissipation is 17.4 BTU/hour. It can be installed in any slot of the ControlLogix chassis. For wiring, it uses unshielded RJ45, Category 5 twisted pair cable connectors to connect to the controller.

To run an Ethernet/IP network, parameters such as IP address, subnet mask, gateway, etc. must be defined. The 1756-EN2TR bridge has multiple functions, such as providing support for messaging, distributed I/O, and labeling. It encapsulates messages in the standard TCP/IP protocol. The ControlNet and DeviceNet network protocols allow it to share a common application layer. 1756-EN2TR does not require any scheduling or routing tables to store information. Other features include explicit protection mode, electronic keys, device level ring network, and parallel redundant protocol network support. 1756-EN2TR is a ControlLogix Ethernet communication module designed specifically for redundant Ethernet networks. This module improves the availability of Ethernet networks by supporting embedded dual RJ545 ports for Ethernet protocol and 10/100 Mbps transmission speed with automatic negotiation function.
