Summary:A communications system for use in a well includes a communications link and a plurality of nodes coupled to the communications link. The plurality of nodes include a transmitting node and responding nodes. The transmitting node adapted to transmit a predefined command (e.g., a special read command), and the responding nodes each includes a control device adapted to respond to the predefined command by transmitting a data block. L'invention concerne un système de communications destiné à être utilisé dans un forage, qui comprend une liaison de transmission de données et une pluralité de noeuds couplée à la liaison de transmission de données. La pluralité de noeuds inclut un noeud de transmission et des noeuds de réponse. Le noeud de transmission, qui est adapté pour transmettre une commande prédéfinie (p. ex. une instruction de lecture spéciale), et les noeuds de réponse incluent chacun un dispositif de commande conçu pour exécuter la commande prédéfinie en transmettant un bloc de données.
