Abstract

Dans un dispositif de surveillance, des unités de traitement (11, 121...12n; 21, 222...22n) constituent une unité principale et des unités asservies qui échangent des informations par l'intermédiaire d'un bus de données (10, 20). Afin de pouvoir envoyer des télégrammes télémétriques par une seule sortie des unités de traitement, l'unité principale et les unités asservies sont raccordées de manière différente à un bus de réception (101, 201) et à un bus d'émission (102, 202) du bus de données (10, 20). En outre, l'unité principale envoie les télégrammes reçus en provenance du bus d'émission (101, 201) au bus de réception (102, 202). Ce dispositif de surveillance est notamment utile pour surveiller des dispositifs de transmission de systèmes de transmission de messages électriques et/ou optiques.
