The 1756-EN2T is a ControlLogix module manufactured by Allen-Bradley/Rockwell Automation as part of the ControlLogix Communication Module series. This unit has an EtherNet/IP interface communication module and supports general messaging, information exchange, and real-time I/O messaging for applications such as synchronization of time, real-time control, and motion. The Allen-Bradley 1756-EN2T comes with a CIP safety standard and allows the simultaneous safety transfer as well as control data and diagnostics information. The module utilizes enhanced communication, physical media, and chips, and it also has EtherNet communication rates of 10 – 100 megabytes per second and uses copper. This ControlLogix module is also compatible with the 256 Logix and the 128 TCP and IP communication connections. This Allen-Bradley module supports an all-out of eight axes for the combined motion on the Ethernet/IP Network and draws a current of 1 amp at 5.1 volts DC. This module comes with a maximum power dissipation of 5.1 watts along with a thermal dissipation of 17.4 BTU per hour. It is flexible and can be used in any slot of the ControlLogix Chassis.
The Allen-Bradley 1756-EN2T ControlLogix module uses category 5, unshielded RJ45, twisted-pair cable connectors to the interface for wiring purposes. When operating the EtherNet/IP network using this module, factors like the IP address, Gateway, and Subnet masks should be defined. The Allen-Bradley 1756-EN2T module bridge features different functions, such as offering support for the tags, messaging, and distributed I/O. It also compresses messages in a standard TCP/IP protocol.

1756-EN2T connection module belongs to the ControlLogix family. Manufactured by Allen-Bradley, it is a 256-connection copper EtherNet/IP bridge. It can be fitted in any ControlLogix chassis slot and It has a 6.2 Watts power dissipation rating and a 21.28 BTU per hour heat dissipation rating. the device operates at speeds of 10 to 100 Mbps via an Ethernet/IP network. This module comes with a USB 1.1 port supporting a full speed of 12 megabits per second as well as an RJ45 Ethernet port for communication. The 1756-EN2T bridge can enable communication, distributed I/O, and tagging, among other things. It wraps messages within the TCP/IP standard protocol. It can share a common application layer thanks to the ControlNet and DeviceNet network protocols. To store information, it does not require any scheduling or routing tables. Other features include a secured mode, electronic keying, a device level ring network, and network compatibility for the parallel redundancy protocol. The module features a per second transfer rate of 10/100 megabits and an isolation voltage of 30 Volts. the isolation voltage is type-tested at 980 Volts AC for 60 seconds and has the fundamental insulation type, Ethernet to Backplane/USB to Backplane/USB to Ethernet connections. Moreover, the 1756-EN2T draws 1.0 amps at 5.1 volts DC and dissipates 6.2 watts. The heat dissipation of the 1756-EN2T is 17.4 BTU per hour. 1756-A4/A7/A10/A13 and –A17 chassis types are compatible with this module. Due to it being an open-type device, the module does not have a rated enclosure, some additional specifications are: 0 to 60 degrees celsius operational temperature range, -40 to 85 degrees celsius storage temperature, and endurance of 2 g vibration at 10 to 500 hertz and 30 g shock (while functioning). Additionally, the module works relative humidity settings of 5 to 95 percent. (non-condensing)
