1756-EN2TR 工业以太网通信模块

Allen-Bradley 1756-EN2TRXT 是一款采用双铜嵌入式开关技术的高性能桥接器。作为 ControlLogix-XT 型号，它增强了对腐蚀性、盐分、湿度、水分/冷凝和真菌生长的保护。它支持信息交换、实时 I/O 消息传递和常规消息传递。通过通用工业协议 （CIP） 安全，它允许通过通用网络同时传输诊断信息和控制数据。它是 ControlLogix EtherNet/IP 网络通信模块的一部分。

ControlLogix-XT 1756-EN2TRXT 桥接器具有坚固的结构，符合 ANSI/ISA2、IEC 和 EMC 标准，是腐蚀性或极端环境的理想选择。它可用于温度范围为 -25-70 °C （-13-158 °F） 的控制应用。在保证产品使用寿命的情况下，将其安装到系统中将有助于降低集成和安装成本。

基于机箱的 1756-EN2TRXT 通信模块可以安装在任何插槽中。它总共有 128 个 TCP 连接、256 个 CIP 连接和 128 + 128 个 CIP 未连接消息（背板 + 以太网）。其在 5.1V DC 时的电流消耗额定值为 1 A。它具有 10-100 Mbps 的通信速率，最多可支持 8 个 CIP 运动轴。它的数据包速率容量为每秒 2000 个 HMI/MSG 数据包。当与 1756-L7x ControlLogix 控制器一起使用时，它的容量为每秒 25，000 个 I/O 数据包。

Allen Bradley 1756-EN2TRXT is a high-performance bridge that utilizes dual copper embedded switch technology. As a ControlLogix-XT model, it enhances protection against corrosion, salinity, humidity, moisture/condensation, and fungal growth. It supports information exchange, real-time I/O messaging, and regular messaging. Through the Common Industrial Protocol (CIP) security, it allows for the simultaneous transmission of diagnostic information and control data through a universal network. It is part of the ControlLogix EtherNet/IP network communication module.

The ControlLogix-XT 1756-EN2TRXT bridge has a sturdy structure that complies with ANSI/ISA2, IEC, and EMC standards, making it an ideal choice for corrosive or extreme environments. It can be used for control applications with a temperature range of -25-70 ° C (-13-158 ° F). Installing the product into the system while ensuring its lifespan will help reduce integration and installation costs.

The 1756-EN2TRXT communication module based on the chassis can be installed in any slot. It has a total of 128 TCP connections, 256 CIP connections, and 128+128 CIP unconnected messages (backplane+Ethernet). Its current consumption rating at 5.1V DC is 1 A. It has a communication rate of 10-100 Mbps and can support up to 8 CIP motion axes. Its packet rate capacity is 2000 HMI/MSG packets per second. When used with the 1756-L7x ControlLogix controller, its capacity is 25000 I/O packets per second.
