Features:

  • Ethernet Communication Module
  • 30 Volts Continuous
  • 32 to 140 degrees Fahrenheit (0 to 60 degrees Celsius)
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 Allen-Bradley Communication module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
Allen-Bradley 1756-EN2T Communication module Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
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. To operate an EtherNet/IP network, parameters such as an IP address, Subnet masks, Gateway, etc. must be defined. 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.
  • Distributed Process Racks:Hazardous field I/O to safe central rack
  • Flow Meter and Custody Transfer Bridging:TCP/Modbus data from meters/gauges
  • Emergency Shutdown System (ESD) Pipelines:SIL2 safety signals for pipeline valves
  • Batch and Recipe Control:Connects ControlLogix to FactoryTalk Batch servers
  • High-Speed Packaging Lines:Fast comms for sensors & pneumatic gates

Align the module: Position the circuit board with the top and bottom guide rails inside the chosen chassis slot.
Slide and seat: Slide the module firmly into the chassis until the top and bottom retaining tabs click, locking the module flush against adjacent cards.
Removal/Insertion Under Power (RIUP): The 1756 architecture supports RIUP, meaning you can install or remove this communication module while chassis backplane power is actively applied without destroying the hardware.

Technical notes

Equipped with a 10/100 Mbps RJ45 Ethernet port, the 1756-EN2T supports EtherNet/IP communications based on the Common Industrial Protocol (CIP). The module facilitates real-time data exchange between controllers, operator interfaces, drives, remote I/O systems, and supervisory applications. Support for produced and consumed tags allows efficient controller-to-controller communications, while explicit messaging capabilities enable data exchange with a wide range of industrial devices.
