1756-EWEB 一款以太网 I/P 增强型 Web 服务器模块

1756-EWEB 一款以太网 I/P 增强型 Web 服务器模块

Allen-Bradley 1756-EWEB，即增强型 Web 服务器，是一个模块，可通过 Web 浏览器访问控制系统中的信息。这还允许使用XML网页对同一机箱内的控制系统数据进行远程监控和修改。1756-EWEB 模块允许您路由消息、闪存升级模块以及上传或下载程序。因此，1756-EWEB模块充当访问目标设备的桥梁。也可以通过此模块创建适合您的应用程序的自定义网页。使用 ASP 函数，您可以使用实时控制器数据填充网页。此功能受到限制，因为 1756-EWEB 模块最多只能存储 5 MB 的网页和数据视图。您还可以通过 1756-EWEB 模块的嵌入式电子邮件编辑器创建电子邮件，以及使用 MSG 指令发送由 Logix 控制器发起的电子邮件。请注意，当您使用界面发送电子邮件时，每次都需要输入所有电子邮件信息。TCP或UDP通信链路也可以通过模块打开到其他标准以太网设备。1756-EWEB 模块可以支持多达 128 个连接的 CIP 连接消息，用于桥接消息、ASP 函数调用、数据调用和 32 个终端节点连接的任意组合。此外，它可以支持多达 256 条未连接的 CIP 消息，其中一半可以从以太网端口到模块上的对象或背板，另一半可以从背板到模块上的对象或以太网端口。模块连接到的每个 IP 地址都使用一个 TCP 连接，模块最多可以支持 64 个 TCP 连接来处理 CIP 连接。安装1756-EWEB模块非常简单;您只需将模块对齐到 1756 ControlLogix 控制器机箱中的插槽，将其滑入直至卡入到位，然后将其连接到网络。

Allen-Bradley 1756-EWEB 是一款 ControlLogix 通信模块。该模块专门用于以太网 I/P 通信桥接模块，允许远程访问 ControlLogix 控制器组件，包括用户程序和硬件配置。

1756-EWEB 带有一个 RJ-45 以太网接口，支持 10/100 Mbps 的传输速度。当提供适当的 IP 地址时，可以使用标准 Web 浏览器访问模块的 Web 服务器功能。

1756-EWEB 是直接安装在 ControlLogix 机箱上的单插槽模块。它可以安装在中央 ControlLogix 机箱所在的本地机箱或分布式 I/O 站上。它与任何 ControlLogix 机箱（如 1756-A4、1756-A7、1756-A10、1756-A13 和 1756-A17）兼容安装。

1756-EWEB 支持使用具有 XML 支持的 Internet Explorer .5 或 6 访问模块生成的网页、创建、编辑数据和查看模块托管的网页时，支持使用任何标准 Web 浏览器。对于简单的代码查看，Internet Explorer 5.5 或 6 是兼容的。

1756-EWEB的网页可以使用默认登录凭据访问。默认用户名是 Administrator，未提供密码。成功登录后，请务必更改默认登录名并提供可提供更高安全性的用户名和密码。

Allen-Bradley 1756-EWEB, the Enhanced Web Server, is a module that allows access to information in a control system through a Web browser. This also allows for remote monitoring and modification of control system data within the same chassis using XML web pages. The 1756-EWEB module allows you to route messages, flash upgrade modules, and upload or download programs. Therefore, the 1756-EWEB module acts as a bridge to the target device. You can also use this module to create custom web pages suitable for your application. Using ASP functions, you can populate web pages with real-time controller data. This functionality is limited because the 1756-EWEB module can only store a maximum of 5 MB of web pages and data views. You can also create emails through the embedded email editor of the 1756-EWEB module, as well as send emails initiated by the Logix controller using the MSG command. Note that when you use the interface to send email, you need to enter all email information each time. TCP or UDP communication links can also be opened to other standard Ethernet devices via modules. The 1756-EWEB module can support up to 128 connected CIP connection messages for any combination of bridging messages, ASP function calls, data calls, and 32 end node connections. In addition, it can support up to 256 unconnected CIP messages, half of which can go from the Ethernet port to an object or backplane on the module, and the other half can go from the backplane to an object or Ethernet port on the module. Each IP address the module connects to uses one TCP connection, and the module can support up to 64 TCP connections to handle CIP connections. Installing the 1756-EWEB module is simple; You simply align the module into the slot in the 1756 ControlLogix controller case, slide it in until it snaps into place, and then connect it to the network.

Allen-Bradley 1756-EWEB is a ControlLogix communication module. This module is specifically designed for Ethernet I/P communication bridge modules that allow remote access to ControlLogix controller components, including user programs and hardware configurations.

The 1756-EWEB comes with an RJ-45 Ethernet interface that supports 10/100 Mbps transfer speeds. The Web server functionality of the module can be accessed using a standard Web browser when the appropriate IP address is provided.

The 1756-EWEB is a single-slot module installed directly into the ControlLogix chassis. It can be installed on the local chassis where the central ControlLogix chassis is located or on a distributed I/O station. It is compatible with any ControlLogix chassis such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17.

1756-EWEB support Any standard Web browser is supported when using Internet Explorer.5 or 6 with XML support to access Web pages generated by the module, create, edit data, and view Web pages hosted by the module. For simple code viewing, Internet Explorer 5.5 or 6 is compatible.

Pages of 1756-EWEB can be accessed with default login credentials. The default user name is Administrator. No password is provided. Upon successful login, be sure to change the default login name and provide a user name and password that provide greater security.
