【英文介绍】
The Allen-Bradley 1756-EN2T is part of the ControlLogix family of communication modules. It is an EtherNet/IP (Ethernet Industrial Protocol) 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-EN2T also features the CIP security standard, which allows for the simultaneous transmission of security and control data as well as diagnostic information. It uses advanced communication chips and physical media.
The 1756-EN2T supports EtherNet/IP communication rates from 10 to 100 Mbps and uses twisted-pair copper media. 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 5.1 volts DC. It has a maximum power consumption of 5.1 watts 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-EN2T 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. It does not require any scheduling or routing tables to store information. Additional features include protected mode, electronic keying, device-level ring networking, and parallel redundancy protocol networking support.
