Introduction
This chapter describes the Web server functions in the Web server CPU module.
Web Server Overview
The Web server enables you to access the Web server CPU module using web browser on your PC in order to monitor the
status or change the device data. You can create your own web pages and download them to the Web server CPU
module. The web pages can be customized for each Web server CPU module.
When the user’s web page is downloaded to the Web server CPU module, the system web page is downloaded at the
same time. On the system web page, the PLC status can be monitored and data register values can be changed. The Web
server CPU module provides CGI so that you can access data register values of the Web server CPU module from a web
browser using JavaScript. The system library is also provided so that you can show data register values on your web page
using system library parts, such as numerical input, bar graph, or trend graph, without special knowledge of JavaScript.
The Web server is protected with basic authentication. Access from people who do not have user name and password
can be prevented.
Folder Structure
The tree structure of the web server functions in the Web server CPU module is shown below:
The imported files or folders in the Project Window of WindLDR are added under the root folder of the user web page. If
the IP address of the Web server CPU module is 192.168.1.5, enter the following URL on the web browser to access the
top page of the system web page.
http://192.168.1.5/system/index.html
When a folder is specified as URL, index.html in the folder is displayed. For example, the following URL opens the same
page with the above URL.
http://192.168.1.5/system/
/index.html:
