The Allen-Bradley 1756-EN2TR is part of the ControlLogix family of communication modules. 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 complies with the CIP safety standard, allowing the simultaneous transmission of security and control data as well as diagnostic information. It uses advanced communication chips and physical media.

The 1756-EN2TR module has an Ethernet /IP communication rate of 10-100 Mbps and uses double copper cables. It supports 256 Logix and 128 TCP/IP communication connections. It can support up to eight axes for integrated motion over Ethernet /IP networks and consumes 1 A current at 1.5V DC. It has a maximum power consumption of 5.1W and a heat dissipation of 17.4 BTU/ hour. It can be installed in any slot in the ControlLogix chassis. In terms of wiring, it uses an unshielded RJ45 Class 5 twisted pair cable connector to connect to the controller. To run an Ethernet /IP network, you must define parameters such as IP address, subnet mask, gateway, and so on.

The 1756-EN2TR bridge has a variety of functions, such as support for messaging, distributed I/O, and markup. It encapsulates the message in the standard TCP/IP protocol. The ControlNet and DeviceNet network protocols allow it to share a common application layer. The 1756-EN2TR does not require any scheduling or routing tables to store information. Additional features include explicit protection modes, electronic keys, device-level ring networking, and parallel redundancy protocol networking support.

The 1756-EN2TR is a ControlLogix Ethernet communication module designed for redundant Ethernet networks. The module improves the availability of Ethernet networks with support for Ethernet protocols and an embedded dual RJ100 port with a 545/10 Mbps transfer speed with auto-negotiation.

The module supports ring and star topologies, as well as qualified partner devices such as Flex IO, POINT IO, redundant Ethernet adapters, CompactLogix, and ControlLogix. The module also supports sending messages to other Allen-Bradley controllers such as SLC 500, PLC-5, and MicroLogix controllers. It is also compatible to communicate with the Human machine interface (HMI), monitoring and data acquisition (SCADA) of the same Allen-Bradley and even third-party products. It can also work with partner modules and third-party gateways, converters and devices.

The module also supports embedded Ethernet communication for computers and programming workstations, so there is no need to purchase an expensive communication adapter to establish a connection to the controller. In addition, the cables required for this module are Class 3 or Class 3 cables, which can be manufactured into communication cables.

The module can establish up to five TCP connections at the same time, and for the Common Industrial Protocol (CIP), up to six connections can be established.
