Industrial networks - Wireless communication network and communication profiles - ISA 100.11a

IEC 62734:2014 provides specifications in accordance with the OSI Basic Reference Model, ISO/IEC 7498-1, (e.g., PhL, DL, etc.). It is intended to provide reliable and secure wireless operation for non-critical monitoring, alerting, supervisory control, open loop control, and closed loop control applications. It defines a protocol suite, including system management, gateway considerations, and security specifications, for low-data-rate wireless connectivity with fixed, portable, and slowly-moving devices, often operating under severe energy and power constraints. The application focus is the performance needs of process automation monitoring and control where end-to-end communication latencies on the order of at least 100 ms can be tolerated.

Réseaux industriels - Réseau de communication sans fil et profils de communication - ISA 100.11a

L'IEC 62734:2014 fournit des spécifications conformes au Modèle de référence de base OSI, ISO/IEC 7498-1, (par exemple: PhL, DL, etc.). Elle vise à assurer le fonctionnement fiable et sécurisé en mode sans fil pour les applications non critiques de contrôle, d'alerte, de commande de surveillance, de commande à boucle ouverte et de commande à boucle fermée. La présente norme définit une suite de protocoles, y compris la gestion de système, des considérations de passerelle et des spécifications de sécurité, pour une connectivité sans fil à bas débit avec des appareils fixes, portatifs et lentement mobiles, fonctionnant souvent sous des contraintes sévères d'énergie et de puissance. L'application est principalement axée sur les besoins de performance du contrôle et de la surveillance d'automation de processus où des latences de communication de bout en bout de l'ordre d'au moins 100 ms peuvent être tolérées.
