Abstract

L'invention concerne un procédé et une unité puce (30) servant à faire réagir ou à activer au moins un participant (40) affecté à au moins un bus de données série (10), notamment à au moins un bus CAN (Controller Area Network), et prévu pour exécuter au moins une application. L'invention vise à améliorer ce procédé et cette unité puce de sorte que des participants individuels (40) du réseau, c'est-à-dire des participants individuels (40) au bus de données (10), peuvent être réveillés de manière sélective et ciblée afin de former de cette manière, en cas de besoin, des sous-réseaux individuels sans devoir réveiller tout le réseau. A cet effet, on ne met d'abord sous tension qu'au moins une unité contrôleur de protocole (42) affectée au participant (40) si au moins un message entrant est en attente sur le bus de données (10).
