Symbol: d07e263dbf795f4bc0a8640e0183af63_d27931f04cfc19a7c0a8640e00c2ab5a

Function: This object is used for configuring the web-based display variant for remote display of the visualization of the controller in a web browser. This allows for remote access, remote monitoring, as well as service and diagnostics of an application over the Internet.

Requirement: The object is inserted below the visualization manager, and the target system has a web server with CODESYS Web Visualization support. The web server allows for the communication between the target system and the web browser.

Start visualization

Name of the visualization where the start is displayed as CODESYS Web Visualization.

Tip: Use input assistance for selecting another visualization.
Name of HTML file

Base URL of the web page. The URL is also specified as the address in the web browser.

Example: http://localhost:8080/webvisu.htm

Note: If you use a BeagleBone Black as a visualization device, then you must note that a BeagleBone Black uses port 9090 for its web server. A valid IP address is as follows: http://192.168.7.2:9090/webvisu.htm
Use as default page

d07e263dbf795f4bc0a8640e0183af63_9a3f06830c0506c5c0a8640e012f0ace : The page specified in Name of HTML file is preset as the default page. Now this page will always open when a user specified in the web browser the IP address and port of the web server that is running on the controller: http://<IP address web server>:<port web server>.

Example: http://localhost:8080

Notice: Even if you have created multiple web visualizations, you can activate this option for exactly one web page only and therefore preset only one page as the default page.
Refresh rate (ms) Refresh rate (in milliseconds) in the web browser
Default size for communication buffer

Default size for communication buffer (in bytes). Defines the maximum available memory for data transfer between the web client and the web server.

Example: 50000

Fixed d07e263dbf795f4bc0a8640e0183af63_331ba40060e030ffc0a8640e014c3b3b : Fixed size of the visualization. The values used are Client height and Client width.
Isotropic d07e263dbf795f4bc0a8640e0183af63_331ba40060e030ffc0a8640e014c3b3b : The size of the visualization is adapted to the dimensions of the web browser, retaining the proportions of the visualization.

This is an advantage when a dialog was created to match the visualization because then they are scaled together.
Client height Height of the visualization (in pixels).
Client width Width of the visualization (in pixels).
