## Protección de referencia circular

La protección de referencia del bucle evita que sus nodos se vuelvan sin responder e inundan su instalación de KNX deshabilitando ambos nodos utilizando el mismo enlace de dirección de grupo.<br/>
Por ejemplo, si vincula la salida ** de un nodo con la dirección de grupo 0/1/1 a la entrada** de otro nodo con la misma dirección de grupo 0/1/1, se activará la protección. <br/>
