8.5.3.6 Task Configuration of the WAGO Controller
The response time of the e!RUNTIME Web visualization largely depends on the
control program, which is processed on the WAGO controller since user input is
processed on the WAGO controller. Therefore, as long as the control application
allows it, the priority of the “VISU_TASK” should be placed in the priority range 4
... 14. The cycle time of the “VISU_TASK” should be as short as possible,
typically in the range of 25 ms ... 100 ms.
8.5.4 HTML5 Web Visualizations
When creating a Web visualization based purely on HTML5 and not on
CODESYS, it is important to know the HTML5 capabilities of the integrated Web
browser to ensure that the visualization can be displayed properly.
The panels use the “QT 4.8.6” or “QtWebkit 2.2” Web browser.
You can obtain detailed information at
https://html5test.com/s/2abdf228f6dd0bc7.html
about which elements, forms,
graphics, etc. are available to you when planning your HTML5 Web visualization.
Use only these elements to ensure the visualization is properly displayed.
In the Web browser, not all elements of the ECMA5 standard are available. E.g.
the function bind() is missing. If possible, you can add this function in your
website by a polyfill:

8.5.5 Graphic Elements
8.5.5.1 Antialiasing
The “Antialiasing” functionality (smooth edges of graphical elements) in the
e!COCKPIT causes an increase in the computing effort in the e!DISPLAY and
should therefore be disabled if you do not have to use this function.
You find the setting in the program structure in the sub-item “Web Visualization”
under “Display Options”.
