<div class="markdown_content"><p>Hallo maddi67,</p> <p>ich gehe mal davon aus, dass in diesem Forum niemand über eine Frage (oder den Fragenden) lacht </p> <p>Nun zu deinem Anliegen:</p> <ol> <li> <p>Um die Systemzeit zu lesen, benötigst du die Bibliothek SysLibRtc.lib. Diese musst du in dein Projekt einbinden.</p> </li> <li> <p>Mit dem Befehl </p> <div class="codehilite"><pre><span></span> <span class="n">Echtzeit</span> <span class="p">:</span><span class="o">=</span> <span class="n">SysRtcGetTime</span><span class="p">(</span><span class="n">dummy</span><span class="p">);</span> <span class="p">(</span><span class="o">*</span> <span class="n">Echtzeit</span> <span class="n">lesen</span> <span class="o">*</span><span class="p">)</span> </pre></div> <p>wird die komplette Datum/Zeit-Information der CPU übernommen. Das bedeutet, die Variable "Echtzeit" muss vom Typ DT sein, also:</p> <div class="codehilite"><pre><span></span> <span class="nt">VAR</span> <span class="nt">Echtzeit</span><span class="o">:</span> <span class="nt">DT</span><span class="o">;</span> <span class="o">(*</span> <span class="nt">Systemzeit</span> <span class="nt">komplett</span> <span class="o">(</span><span class="nt">z</span><span class="p">.</span><span class="nc">B</span><span class="o">.</span> <span class="nt">DT</span><span class="p">#</span><span class="nn">2006-11-21-18</span><span class="p">:</span><span class="nd">42</span><span class="p">:</span><span class="nd">31</span><span class="o">)</span> <span class="nt">im</span> <span class="nt">Format</span> <span class="nt">DT</span> <span class="o">*)</span> </pre></div> </li> <li> <p>Diese DT-Info muss gewandelt werden in einen String</p> <div class="codehilite"><pre><span></span> <span class="nt">Echtzeit_String</span><span class="o">:=</span><span class="nt">DT_TO_STRING</span><span class="o">(</span><span class="nt">Echtzeit</span><span class="o">);</span> <span class="o">(*</span> <span class="nt">Echtzeit</span> <span class="nt">umwandeln</span> <span class="nt">in</span> <span class="nt">String</span> <span class="o">*)</span> </pre></div> </li> <li> <p>Je nach Bedarf werden die einzelnen Informationen vereinzelt und nach Int gewandelt. </p> <div class="codehilite"><pre><span></span> <span class="nt">Jahr</span><span class="o">:=</span><span class="nt">STRING_TO_INT</span><span class="o">(</span><span class="nt">MID</span><span class="o">(</span><span class="nt">Echtzeit_String</span><span class="o">,</span> <span class="nt">4</span><span class="o">,</span> <span class="nt">4</span><span class="o">));</span> <span class="nt">Monat</span><span class="o">:=</span><span class="nt">STRING_TO_INT</span><span class="o">(</span><span class="nt">MID</span><span class="o">(</span><span class="nt">Echtzeit_String</span><span class="o">,</span> <span class="nt">2</span><span class="o">,</span> <span class="nt">9</span><span class="o">));</span> <span class="nt">Tag</span><span class="o">:=</span><span class="nt">STRING_TO_INT</span><span class="o">(</span><span class="nt">MID</span><span class="o">(</span><span class="nt">Echtzeit_String</span><span class="o">,</span> <span class="nt">2</span><span class="o">,</span> <span class="nt">12</span><span class="o">));</span> <span class="nt">Stunde</span><span class="o">:=</span><span class="nt">STRING_TO_INT</span><span class="o">(</span><span class="nt">MID</span><span class="o">(</span><span class="nt">Echtzeit_String</span><span class="o">,</span> <span class="nt">2</span><span class="o">,</span> <span class="nt">15</span><span class="o">));</span> <span class="nt">Minute</span><span class="o">:=</span><span class="nt">STRING_TO_INT</span><span class="o">(</span><span class="nt">MID</span><span class="o">(</span><span class="nt">Echtzeit_String</span><span class="o">,</span> <span class="nt">2</span><span class="o">,</span> <span class="nt">18</span> <span class="o">));</span> <span class="nt">Sekunde</span><span class="o">:=</span><span class="nt">STRING_TO_INT</span><span class="o">(</span><span class="nt">MID</span><span class="o">(</span><span class="nt">Echtzeit_String</span><span class="o">,</span> <span class="nt">2</span><span class="o">,</span> <span class="nt">21</span><span class="o">));</span> </pre></div> </li> </ol> <p>Alle Variablen müssen natürlich vereinbart werden.

<div class="markdown_content"><p>Hallo,</p> <p>bitte nicht lachen, bin noch Anfänger in Codesys.</p> <p>Ich möchte einer Variablen die Systemzeit zuweisen.</p> <p>Wenn dann die Variable einer vogegebenen Zeit (hh.mm.ss) entspricht,</p> <p>soll eine weitere Variable auf TRUE bzw. False gesetzt werden.</p> <p>Kann mir jemand sagen wie´s geht ?</p> <p>Danke</p> <p>Martin</p></div>
