## Protection de référence circulaire

La protection de référence de boucle empêche vos nœuds de ne pas répondre et inonde votre installation KNX en désactivant les deux nœuds en utilisant le même lien d'adresse de groupe.<br/>
Par exemple, si vous liez la sortie **d'un nœud avec l'adresse de groupe 0/1/1 à la** entrée d'un autre nœud avec la même adresse de groupe 0/1/1, la protection sera activée. <br/>
