1756-ENET 接口通信模块 支持常规消息传递

【产品详情】

Allen-Bradley 1756-ENET 是一款 ControlLogix 通信模块。它是一种EtherNet/IP（以太网工业协议）接口通信模块。该公司已停产，取而代之的是具有相同规格的新型号 1756-ENBT。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-ENET 还允许同时传输安全和控制数据以及诊断信息，从而满足 CIP 安全标准。它使用先进的通信芯片和物理介质。1756-ENET 模块具有 100 Mbps 的 EtherNet/IP 通信速率，并使用铜线。它支持 128 个 Logix 和 64 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。它在 5.1V DC 时消耗 700 mA 电流，在 24V DC 时消耗 3 mA 电流。它的最大功耗为 3.7 W，散热为 12.6 BTU/小时。它可以安装在 ControlLogix 机箱的任何插槽中。在接线方面，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 EtherNet/IP 网络，必须定义 IP 地址、子网掩码、网关等参数。1756-ENET 网桥具有多种功能，例如为消息传递、分布式 I/O 和标记提供支持。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通用的应用层。它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、设备级环形网络和并行冗余协议网络支持。

1756-ENET 是 Allen-Bradley 的以太网通信接口。该模块是 ControlLogix 平台的一部分。它是制造商于 2020 年 12 月宣布停产的第一代 ControlLogix 模块之一。该模块带有一 （1） 个支持以太网协议的 RJ-45 接口和一 （1） 个用于模块维护和本地化配置的 AUI 端口。

1756-ENET 是一个单插槽模块，因此它占用机箱的单个插槽。它兼容安装在 A 系列和 B 系列 ControlLogix 机箱中，特别是 1756-A4、-A7、-A10、-A13 以及 A 系列和 B 系列电源，例如 1756-PA72 和 1756-PB72 电源。

1756-ENET 可配置为用作扫描器或适配器模块。它可以用于基于以太网的分布式 I/O 配置，允许对 I/O 数据进行实时控制。它还支持优化的机架配置以及执行 I/O 消息传递。它还与通用工业协议 （CIP） 系统协议兼容。

它还具有前面板 LED 指示灯，例如 RXD 和 TXD LED，用于监控接收和发送的数据，以及用于监控模块整体状态的模块 OK LED。模块的 MAC 地址印在模块的前面板上，可以通过翻转模块平开门来查看。

【英文介绍】

The Allen-Bradley 1756-ENET is a ControlLogix communication module. It is an EtherNet/IP (Ethernet Industrial Protocol) interface communication module. The company has been discontinued and replaced with a new model 1756-ENBT with the same specifications. 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-ENET also allows the simultaneous transmission of security and control data as well as diagnostic information, thus meeting CIP safety standards. It uses advanced communication chips and physical media. The 1756-ENET module has an EtherNet/IP communication rate of 100 Mbps and uses copper wires. It supports 128 Logix and 64 TCP/IP communication connections. It can support up to 8 axes for integrated motion over Ethernet /IP networks. It consumes 700 mA of current at 5.1V DC and 3 mA of current at 24V DC. It has a maximum power consumption of 3.7W and a heat dissipation of 12.6 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-ENET 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 explicit protection modes, electronic keys, device-level ring networking, and parallel redundancy protocol networking support.

The 1756-ENET is an Ethernet communication interface for Allen-Bradley. This module is part of the ControlLogix platform. It is one of the first-generation ControlLogix modules that the manufacturer announced it was discontinuing in December 2020. The module comes with one (1) RJ-45 interface for Ethernet protocol support and one (1) AUI port for module maintenance and localization configuration.

The 1756-ENET is a single slot module, so it occupies a single slot in the chassis. It is compatible to be installed in A Series A and B Series ControlLogix enclosures, especially 1756-A4, -A7, -A10, -A13, and A and B Series power supplies, such as 1756-PA72 and 1756-PB72 power supplies.

The 1756-ENET can be configured to be used as a scanner or adapter module. It can be used for Ethernet-based distributed I/O configurations, allowing real-time control of I/O data. It also supports optimized rack configurations and performs I/O messaging. It is also compatible with the Common Industrial Protocol (CIP) system protocol.

It also has front panel LED indicators, such as RXD and TXD leds, for monitoring data received and sent, and a module OK LED for monitoring the overall status of the module. The MAC address of the module is printed on the front panel of the module and can be viewed by flipping the module flat door.
