    Hi all,

    I encountered a for me unexpected difference between the view of a textbox in the Codesys preview window and different Webbrowsers.

    When I am running the program on the PLC, Codesys shows the visualization as shown in the attachment. However, different webbrowsers (Chrome, Safari, Firefox) show the textbox in a different way, as shown in the other attachment.

    I tried to changing the scaling options and tried different fonts, but that doesn't fix the problem.

    Do you have any thoughts on this issue?

    Thanks in advance!

    Kind regards,

    Hello Joren,

    a difference between the CODESYS Online Visualization and the CODESYS Web-Visualization is that the webvisu uses the default scaling anisotropic and the codesys online visu shows the visualization in scaling fixed.
    You can change this setting in your "Web-Visualization" below the visu manager.

    Could you maybe attach a example project? I would like to take a quick look at this but I would need the following information:
    Used browser and version
    Used OS and version

    Best regards,
