Abstract

L'invention concerne un contrôleur programmable (PLC) présentant une fonction de communication sans fil permettant de communiquer avec un dispositif périphérique d'un PLC par un module de communication dans lequel un module Bluetooth est inséré. Dans un PLC doté d'un module de puissance, d'une unité centrale (CPU) et d'un module de communication, (1) le module CPU communique avec le module de communication par l'insertion d'un module Bluetooth prenant en charge une communication sans fil de courte distance, dans le module de communication susmentionné; (2) un dispositif asservi du PLC doté d'un module Bluetooth peut communiquer avec un PLC. Ainsi, les coûts et les défauts sont réduits et la maintenance est facile. L'invention permet également de simplifier les composants d'un système et d'éliminer une restriction d'espace.
