<p>danke für Deine schnelle Hilfe, hat gut funktioniert.</p>
<p>Die Subnet Mask kann man dann noch mit der Funktion:</p>
<p>SysSockGetSubnetMask(szIPAddress:=sIPAdress , szSubnetMask:=sMask , diMaxSugnetMask:=SIZEOF(sMask) );</p>
<p>ermitteln. Die Funktion liefert durch eingabe der ermittelten IP - Adresse die Netmask zurück.</p>
<p>Für die Ermittlung des Standard Gateway habe ich leider noch nichts gefunden, ist mir aber ersteinmal auch nicht <br/>
so wichtig, mal sehen vielleicht find ich da irgendwann mal was.</p>

<p>Ob Gateway usw auch geht musst du mal schauen... ist mal ein Anfang.<br/>

<p>hat jemand eine Ahnung, ob es eine Möglichkeit gibt Systeminformationen des Raspberry in CoDeSys zu integrieren?</p>
<p>In meinem Fall würde ich gerne die aktuelle IP - Adresse sowie die Netzmaske und das Standardgateway auslesen und <br/>
in der Visu sowie auf einem LCD Display anzeigen.</p>
<p>Danke schon im Voraus für Eure Antworten.</p></div>
