Type: Communication module
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 allows the simultaneous transmission of security and control data as well as diagnostic information, thus complying with CIP security standards. It uses advanced communication chips and physical media.
The 1756-EN2TR module has a 10-100 Mbps Ethernet /IP communication rate 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 5.1V DC. It has a maximum power consumption of 5.1W and a heat dissipation of 17.4 BTU/hr. 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 providing support for messaging, distributed I/O, and labeling. It encapsulates the message in the standard TCP/IP protocol. The ControlNet and DeviceNet network protocols allow it to share a common application layer. 1756-EN2TR does not require any scheduling or routing tables to store information. Additional features include explicit protection mode, electronic keying, device-level ring networking, and parallel redundancy protocol networking support.
The 1756-EN2TR is a ControlLogix Ethernet communication module designed for redundant Ethernet networks. With embedded dual RJ545 ports, support for Ethernet protocols and 10/100 Mbps transfer speeds with auto-negotiation, the module improves the availability of Ethernet networks.
