NEXTO XF #85 - Accessing the web server through the browser

The objective of this tutorial is to explain how to access the web server of the XF325-W CPU through the browser.

Components

Equipment: 1 computer/notebook.

                            1 325-W

Software:  MasterTool X

Tutorial Sections

1. ARCHITECTURE
2. DEVELOPMENT

1. ARCHITECTURE

A computer/notebook will be required to use MasterTool X.

2. DEVELOPMENT

After creating the visualization in the project, the user can access it through a browser using the PLC Web Server, allowing monitoring and control directly through the web page.

Important note

For this procedure:

• It is necessary to use a physical PLC (XF325-W)
• It does not work in simulation only
• The PLC must have the Web Server active (via project download)

This occurs because the controller will open a web port to make the visualization available.

Prerequisites

• Computer connected to the PLC (directly or through a network)
• Project with Visualization configured
• Download completed successfully
• CPU in RUN mode

Step-by-step

1. Connect the computer to the PLC
2. Perform the project download normally
3. After the download, set the CPU to RUN

Access through the browser

With the PLC running:

1. Open any browser, such as:
   • Google Chrome
   • Microsoft Edge
   • Opera
2. In the address bar, enter:

PLC_IP:8080/webvisu.htm

Example:

192.168.15.1:8080/webvisu.htm

Operation

After accessing it:

• The browser will load the graphical interface created in MasterTool
• The PLC Web Server instance will be opened

Available features

On the web page, the user will be able to:

• Supervise the process
• View variable states
• Interact with the application
• Send commands

Example:

• Activate a Boolean variable
• Turn outputs on/off
• Change values
