DA et AD sont des termes que l'on entend souvent lorsqu'on utilise l'automate.
\nD fait r\u00e9f\u00e9rence \u00e0 la quantit\u00e9 num\u00e9rique<\/strong>c'est-\u00e0-dire Num\u00e9rique, et A se r\u00e9f\u00e8re \u00e0 la quantit\u00e9 analogique<\/strong>c'est-\u00e0-dire Analogique.
\nL'information num\u00e9rique est discontinue, alors que l'information analogique est continue.<\/strong><\/p>\n<\/div><\/div><\/div>

Les types de signaux num\u00e9riques les plus courants sont les suivants PNP, NPN, relais, compteur, impulsion, etc.<\/strong>.
\nLes types de signaux analogiques les plus courants sont les suivants courant, tension, temp\u00e9rature du thermocouple, temp\u00e9rature de la r\u00e9sistance thermique, pression, etc.<\/strong>
\nDA est num\u00e9rique vers analogique, AD est analogique vers num\u00e9rique.
\nPuisque la quantit\u00e9 analogique peut \u00eatre collect\u00e9e, la commande de sortie de l'API doit \u00eatre une quantit\u00e9 num\u00e9rique, de sorte que DA se r\u00e9f\u00e8re g\u00e9n\u00e9ralement au type d'entr\u00e9e IO, et AD se r\u00e9f\u00e8re au type de sortie IO.<\/p>\n<\/div><\/div><\/div>
