prog modicon
Bonjour, je dois programmer plusieurs modicon avec principalement des entrées numériques que je dois ensuite aller lire sur un as-p pour une supervision. J'ai crée des lignes de prog pour chaque entrée avec en bout une bobine avec un %M0 %M1 etc mais sur l'asp je n'arrive pas à le lire.
J'ai bien créé le modbus tcp device ensuite j'ai essayé point par point ou alors des points d'entrée multi-bit sans succès je ne vois jamais cette valeur changer.
Du coup sur le modicon ai-je bien programmer ?
ps : J'ai bien trouver mon modicon sur la workstation

Good day Anthony,
Yes your programme is correct, however the data type for the %M would be Output Bits in the SCADA. I would rather recommend using holding Register bits. You can choose a %MW and map all the bits to it in the format %MW101:X0-X15 like in this example
