<div class="markdown_content"><p>Hallo,</p> <p>ist in ST relativ einfach. Angenommen, Du packst das ganze in einen FB, dann braucht der einen Eingang für den Taster und je einen Eingang für die Sensoren. Dann braucht er noch einen Ausgang für das aktuell ausgewählte Sensorsignal.</p> <p>Vom Taster musst Du die Flanke auswerten und damit einen Zähler hochzählen. Der Zählerstand wählt den betreffenden Sensor aus.</p> <p>Beispiel:</p> <div class="codehilite"><pre><span></span><span class="nv">FUNCTION_BLOCK</span> <span class="nv">Sensor</span> <span

<div class="markdown_content"><p>Hallo,</p> <p>ich habe 4 Sensoren. Wenn die Taste 1 betätigt worden ist, bekomme ich Eingangsignal vom Sensor 1, wenn Taste 2 - vom Sensor 2 usw. Wie kann ich diese Aufgabe in FUP oder ST realisieren?</p> <p>Danke schön im Voraus!</p></div>
