[Introduction]：La série M31-U-PN est un module hôte d'E/S distribuées à distance compatible avec le protocole Profinet, utilisé pour mapper les données d'E/S vers Profinet. Son intégration s'effectue via des fichiers GSD, permettant aux automates programmables de lire et d'écrire sur les ports d'E/S sans programmation. Ce module est compatible avec différents modèles d'automates Siemens, notamment les S7-200smart, S7-300, S7-200, S7-1500 et S7-1500. Il dispose de deux ports réseau, prend en charge les fonctions de commutation et intègre une passerelle Profinet vers Modbus RTU. Le produit est recouvert d'un revêtement de protection contre les moisissures, l'humidité et les embruns salins.
