艾伦-布拉德利1756-EWEB或增强型网络服务器是一个模块，通过网络浏览器提供对控制系统信息的访问。这也允许使用XML网页远程监控和修改同一机架内的控制系统数据。1756-EWEB模块可让您发送消息、闪存升级模块以及上传或下载程序。因此，1756-EWEB模块充当了访问目标设备的桥梁。还可以通过该模块创建适合您的应用程序的自定义网页。使用ASP功能，您可以用实时控制器数据填充您的网页。此功能是有限的，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信息，以及使用MSG指令发送由Logix控制器发起的电子邮件。注意，使用界面发送邮件时，每次都需要输入所有的邮件信息。还可以通过该模块打开与其他标准以太网设备的TCP或UDP通信链接。一个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功能调用和数据调用以及32个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发送到模块上的对象或背板，另一半可以从背板发送到模块或以太网端口上的对象。一个TCP连接用于模块连接到的每个IP地址，并且模块可以支持多达64个TCP连接来处理CIP连接。安装1756-EWEB模块很简单；您只需将模块对准1756 ControlLogix控制器机箱中的插槽，将其滑入，直到其卡入到位，然后将其连接到网络。
艾伦-布拉德利1756-EWEB是一个ControlLogix通信模块。该模块是一个以太网I/P通信桥模块，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配有一个支持10/100 Mbps传输速度的RJ-45以太网接口。当提供有适当的IP地址时，可以使用标准网络浏览器来访问模块的网络服务器功能。
1756-EWEB是一个单槽模块，可直接安装到ControlLogix机箱上。它可以安装在中央ControlLogix机箱所在的本地机箱上，也可以安装在分布式I/O工作站上。它可与任何ControlLogix机箱兼容安装，如1756-A4、1756-A7、1756-A10、1756-A13和1756-A17。
1756-EWEB支持使用任何标准网络浏览器访问模块生成的网页，创建、编辑数据，并使用支持XML的Internet Explorer .5或6查看模块托管的网页。对于简单的代码查看，兼容internet explorer 5.5或6。
可以使用默认登录凭证访问1756-EWEB的网页。默认用户名是Administrator，没有提供密码。成功登录后，更改默认登录并提供更安全的用户名和密码非常重要。
The Allen-Bradley 1756-EWEB, or Enhanced Web Server, is a module that provides access to information from the control system via a web browser. This also allows for the remote monitoring and modification of control system data, which is within the same chassis, using XML web pages. The 1756-EWEB module lets you route messages, flash upgrade modules, and upload or download programs. Thus, the 1756-EWEB module acts as a bridge to access the target device. Custom web pages that are fitting for your application can also be created through this module. With the ASP function, you can populate your web page with live controller data. This feature is limited because the 1756-EWEB module can only store up to 5 MB worth of web pages and data views. You can also create email messages through the 1756-EWEB module’s embedded email composer, as well as send an email initiated by a Logix controller using an MSG instruction. Note that when you use the interface to send an email, you need to enter all the email information every time. TCP or UDP communication links to other standard Ethernet devices can also be opened through the module. A 1756-EWEB module can support CIP connected messages of up to 128 connections for any combination of bridged messages, ASP function calls, and data calls and 32 end-node connections. Additionally, it can support up to 256 unconnected CIP messages, half of which can be from the Ethernet port to an object on the module or to the backplane and the other half can be from the backplane to an object on the module or the Ethernet port. One TCP connection is used for every IP address that the module is connected to and the module can support up to 64 TCP connections that will handle the CIP connections. Installing the1756-EWEB module is straightforward; you just need to align the module to a slot in the 1756 ControlLogix controller’s chassis, slide it in until it snaps into place, and then connect it to a network.
The Allen-Bradley 1756-EWEB is a ControlLogix communication module. This module is specifically an Ethernet I/P communication bridge module which permit remote access to the ControlLogix controller assembly including the user programs and hardware configuration.
The 1756-EWEB comes with a single RJ-45 Ethernet interface that supports a 10/100 Mbps transmission speed. When provided with an appropriate IP address, the module’s web server functionality may be accessed using a standard web browser.
The 1756-EWEB is a single slot module that install directly to a ControlLogix chassis. It may be installed to a local chassis, where the central ControlLogix chassis resides or to a distributed I/O station. It is compatible for installation with any ControlLogix chassis such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17.
The 1756-EWEB supports use of any standard web browser when used for accessing of web pages generated by the module, create, edit data, and view web pages hosted by the module using Internet Explorer .5 or 6 with XML support. For simple code viewing, internet explorer 5.5 or 6 is compatible.
The 1756-EWEB’s web pages can be accessed using the default login credentials. The default username is Administrator without a password provided. When successfully logged-in, it is important to change the default log-in and provide a username and password that offers greater security.
