This fourth edition cancels and replaces the third edition published in 2020. This edition constitutes a technical revision. IEC 62541-5:2026 definit le Modele dinformation. Le Modele dinformation decrit des Nouds normalises de lAddressSpace dun Serveur.

LAnnexe C normative definit le Systeme de description de Type OPC Binary. LAnnexe B fait reference aux informations dencodage pour les DataTypes personnalises dans les versions precedentes du present document.
