- Ethernet modules supports 10/100 Mbps transmission speed
It is a dual-port Ethernet/IP (Industrial Ethernet Protocol) communication module. This module supports general messaging, real-time I/O messaging, and information exchange, suitable for applications such as real-time control, time synchronization, and motion control. The 1756-EN2TR complies with CIP safety standards and can simultaneously transmit safety data, control data, and diagnostic information. It utilizes advanced communication chips and physical media.
It supports 256 Logix connections and 128 TCP/IP connections. In an Ethernet/IP network, it can support up to 8-axis integrated motion control, operating at 5.1V DC and 1A current. Its maximum power consumption is 5.1W, and its heat dissipation is 17.4 BTU/hr. It can be installed in any slot within a ControlLogix chassis. For connectivity, it uses unshielded RJ45 Category 5 twisted-pair connectors to connect to the controller. To operate an Ethernet/IP network, parameters such as IP address, subnet mask, and gateway must be defined.
The 1756-EN2TR Allen Bradley Communication module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 1756-EN2TR bridge offers a variety of features, including support for messaging, distributed I/O, and tags. It encapsulates messages within the standard TCP/IP protocol. ControlNet and DeviceNet network protocols allow it to share a common application layer. The 1756-EN2TR requires no scheduling or routing tables to store information. Other features include explicit protection mode, electronic keys, device-level ring networks, and parallel redundancy protocol network support.
1. Network Redundancy (DLR): Its dual-port design is specifically tailored for Device-Level Ring (DLR) topologies, enabling the network to "self-heal" within 3 milliseconds even in the event of a cable break. This is crucial for critical industries such as oil and gas, chemicals, and power generation.
2. High-Speed Motion Control: Supports up to 8 coordinated motion axes via EtherNet/IP, making it suitable for synchronous automation systems such as packaging lines and robotic cells.
3. Distributed I/O and Messaging: Enables real-time I/O messaging and general data exchange between the ControlLogix chassis and remote devices.
4. Scalable Architecture: Supports daisy-chaining of up to 63 devices without the need for external switches, simplifying modular automation systems.
