1756-EN2TR is an Ethernet module produced by Rockwell Automation,USA,and is part of the Allen-Bradley ControlLogix communication module series.The following is a detailed introduction to the 1756-EN2TR Ethernet module:

I.Main functions and applications

The 1756-EN2TR module is an Ethernet/IP(Ethernet Industrial Protocol)dual-port interface communication module,which is mainly used to connect the controller to the Ethernet to achieve high-speed data transmission and remote monitoring.It supports conventional messaging,real-time I/O messaging,and information exchange for applications such as real-time control,time synchronization,and motion.The module can also transmit safety and control data and diagnostic information at the same time,in compliance with CIP safety standards.

II.Technical features

High-speed communication:The 1756-EN2TR module supports Ethernet/IP communication rates of 10~100Mbps,which can meet the high-speed data transmission requirements in industrial environments.

Flexible configuration:Users can set the module’s IP address,subnet mask and other network parameters through software,and easily integrate it into various network environments.

Multi-connection support:The module supports up to 256 Logix and 128 TCP/IP communication connections,and can exchange data with multiple devices at the same time.

Integrated motion control:The 1756-EN2TR module can support up to 8 axes for integrated motion control on Ethernet/IP networks,which improves the flexibility and control accuracy of the system.

Fault diagnosis and recovery:The module has built-in fault diagnosis and recovery mechanisms,which can effectively deal with network failures and ensure the stable operation of the system.

3.Installation and compatibility

The 1756-EN2TR module can be installed in any slot of the ControlLogix chassis and is compatible with various Allen-Bradley ControlLogix controllers.In addition,it also supports a variety of programming languages​​and programming tools,such as RSLogix 5000 or Studio 5000,etc.,which is convenient for users to configure and maintain.

4.Application scenarios
