1756-EN2TR 以太网通信模块
【产品详情】
Allen-Bradley 1756-EN2TR是ControlLogix通信模块系列的一部分。它是一种以太网/IP（以太网工业协议）双端口接口通信模块。它支持常规消息传递、实时 I/O 消息传递以及实时控制、时间同步和运动等应用程序的信息交换。1756-EN2TR 还允许同时传输安全和控制数据以及诊断信息，从而符合 CIP 安全标准。它使用先进的通信芯片和物理介质。
1756-EN2TR 模块具有 10 - 100 Mbps 以太网/IP 通信速率，并使用双铜缆。它支持 256 个 Logix 和 128 个 TCP/IP 通信连接。它最多可以支持 8 个轴，用于以太网/IP 网络上的集成运动，并在 1.5V DC 时消耗 1 A 电流。它的最大功耗为 5.1 W，热耗散为 17.4 BTU/小时。它可以安装在 ControlLogix 机箱的任何插槽中。对于接线，它使用非屏蔽 RJ45、5 类双绞线电缆连接器与控制器连接。要运行以太网/IP 网络，必须定义 IP 地址、子网掩码、网关等参数。
1756-EN2TR 桥接器具有多种功能，例如为消息传递、分布式 I/O 和标签提供支持。它将消息封装在标准 TCP/IP 协议中。ControlNet 和 DeviceNet 网络协议允许它共享一个公共应用层。1756-EN2TR 不需要任何调度或路由表来存储信息。其他功能包括显式保护模式、电子密钥、设备级环网和并行冗余协议网络支持。
1756-EN2TR 是一款 ControlLogix 以太网通信模块，专为冗余以太网网络而设计。通过支持以太网协议的嵌入式双RJ545端口和具有自动协商功能的10/100 Mbps传输速度，该模块提高了以太网网络的可用性。
该模块支持环形和星形拓扑，以及合格的合作伙伴设备，如 Flex IO、POINT IO 冗余以太网适配器、CompactLogix 和 ControlLogix。该模块还支持向其他 Allen-Bradley 控制器（如 SLC 500、PLC-5 和 MicroLogix 控制器）实现消息。它还兼容与相同的Allen-Bradley甚至第三方产品的人机界面（HMI），监督控制和数据采集（SCADA）进行通信。它也可以与包含合作伙伴模块和第三方网关、转换器和设备合作。
该模块还支持计算机和编程工作站的嵌入式以太网通信，因此，无需购买昂贵的通信适配器即可建立与控制器的连接。此外，该模块所需的电缆是 3 类或 3 类电缆，可以制造成通信电缆。
使用此模块最多可同时建立 5 个 TCP 连接，而对于通用工业协议 （CIP），最多可以进行 6 个连接。
IP地址的初始配置或设置可以使用Allen-Bradley BOOTP-DHCP工具进行。BOOTP-DHCP工具不仅用于此模块，还用于Allen-Bradley制造的各种以太网设备。

【英文介绍】
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 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. For 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 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. 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. With embedded dual RJ545 ports that support Ethernet protocols and 10/100 Mbps transfer speeds with auto-negotiation, the module improves Ethernet network availability.
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 implementing messages to other Allen-Bradley controllers such as SLC 500, PLC-5, and MicroLogix controllers. It is also compatible with the Human machine interface (HMI), supervised control and Data acquisition (SCADA) of the same Allen-Bradley and even third-party products for communication. 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.
With this module, up to 5 TCP connections can be established simultaneously, and for the Common Industrial Protocol (CIP), up to 6 connections can be made.
The initial configuration or setting of an IP address can be done using the Allen-Bradley BOOTP-DHCP tool. The BOOTP-DHCP tool is not only used for this module, but also for various Ethernet devices manufactured by Allen-Bradley.
