    Hi All.

    I'm having some problems accessing my software webvisu PLC. I'm accessing via external access, but so I can load the initial screen of my system and when you click a bitmap screen to change the system does not respond.

    The console of Java is returning me this output.

    What catches my attention is the penultimate line of the console where he talks: General Error: PLC not available.

    The Webvisu may be losing communication with the PLC?

    Suggestions are very welcome.

    Applet initialised
Version = V2.3.9.24
STARTVISU = PLC_VISU

    startup ethernet settings
    have your PC the same ip addres except the last digits.
    then it should work, otherwise tell us the settings in ethernet settings.
