Abstract

Lorsqu'une panne se produit dans l'une quelconque des unités de commande numérique (20, 30 et 40), un ordinateur hôte (11) charge dans l'unité de commande numérique un programme de diagnostic de la panne, et effectue ledit diagnostic. Les données requises sont ensuite transférées depuis l'unité de commande numérique vers l'ordinateur hôte (11). Par conséquent, un technicien de maintenance peut déterminer la panne survenue dans l'unité de commande numérique grâce à l'analyse des données visualisées à l'écran de l'ordinateur hôte (11).
