<div class="markdown_content"><p>Hi,</p> <p>1) hier in der FAQ Section dieses Beispiel abändern und einen 'shutdown -h now' aufrufen:<br/> <a class="" href="http://forum.codesys.com/viewtopic.php?f=23&amp;t=6247&amp;x=12699&amp;p=12711&amp;lan=en" rel="nofollow">http://forum.codesys.com/viewtopic.php? ... 699#p12711</a><br/> 2) ja das würde auch unter Windows gehen.<br/> Grüße<br/> Edwin</p></div>
