    I have Wago 750-841 PLC but I've some problems with web visualisation.
    I downladed program and visulalisation files.I can enter into the "Web Management System" everything is ok until this section.
    But when I try to open web visualisation page,Java is loading but only a white page is appearing and it gives the error " lost monitoring connection ".

    I checked these;

    -My Java is the latest version.
    -I stopped the windows firewall.
    -My web visu name is PLC_VISU

    I don't know what is preventing to seeing visualisation page at web browser...
    If anyone help me about my problem,I'll be pleased..
    Thank you,in advance...

    Cyril,
    Thank you for helping.
    I solved the problem.
    I was because of the wrong selection of windows regional language.
    I changed it to English and it is solved.
