<div class="markdown_content"><p>Hi All.</p> <p>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.</p> <p>The console of Java is returning me this output.</p> <p>What catches my attention is the penultimate line of the console where he talks: <span style="color: #FF0000;">General Error: PLC not available</span>. </p> <p>The Webvisu may be losing communication with the PLC?</p> <p>Suggestions are very welcome.</p> <div class="codehilite"><pre><span></span><span class="n">Applet</span> <span class="n">initialised</span> <span
