Abstract

Le problème décrit par l'invention est de pourvoir à un système de machines industrielles dans lequel un opérateur peut faire fonctionner en toute sécurité chaque machine d'une pluralité de machines industrielles à l'aide d'un terminal de fonctionnement. La solution selon l'invention porte sur un système de machines industrielles (SYS) qui comprend un terminal de fonctionnement (100) et une pluralité de machines industrielles (201 à 203). Chacune des machines industrielles (201 à 203) possède une première unité de commande (224), et le terminal de fonctionnement (100) présente une seconde unité de commande (50). La première unité de commande (224) et la seconde unité de commande (50) permettent un échange sans fil de signaux entre l'une des machines industrielles (201 à 203) et ledit terminal de fonctionnement (100), à condition qu'une première unité de fonctionnement (221) dans l'une des machines industrielles (201 à 203) ait été actionnée, et qu'une seconde unité de fonctionnement (20) dans ce terminal de fonctionnement (100) ait été actionnée.
