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.

Wago 750-841 Web Visualisation - monitoring problem

2020-02-27T19:14:05.940000Z

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...

Murat
