Selon la solution technique de l'invention, lorsqu'une grappe de transmission nouvellement ajoutée fournit un service de transmission de données en continu, un code de configuration de communication correspondant est directement téléchargé pour ajouter une fonction de programmation de la grappe de transmission nouvellement ajoutée à un client sans qu'il soit nécessaire d'exécuter une mise à jour d'application. De la sorte, une mise à jour à chaud de la fonction de programmation de la grappe de transmission nouvellement ajoutée est exécutée, et le manque de praticité et le retard de mise à jour d'une application sont évités.
