<div class="markdown_content"><p>Hallo,</p> <p>wie kann ich die Länge eines Impulses messen der über einen Dig.Eingang kommt? Ich möchte lediglich eine Ausgabe in Sekunden die ein Signal/Impuls an einem Eingang ansteht.</p> <p>Mein System besteht aus einer WAGO 750-841 + 1x750-430.</p> <p>Gruß hwesbe</p></div>
