Industrial communication networks - Fieldbus specifications - Part 6-3: Application layer protocol specification - Type 3 elements

IEC 61158-6-3:2019 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 2 fieldbus. The term “time-critical” is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life.
This International Standard specifies interactions between remote applications and defines the externally visible behavior provided by the Type 2 fieldbus application layer. The purpose of this document is to define the protocol provided to
a) define the wire-representation of the service primitives defined in this document, and
b) define the externally visible behavior associated with their transfer. This document specifies the protocol of the Type 2 fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application layer structure (ISO/IEC 9545).
This fourth edition includes the following significant technical changes with respect to the previous edition:
- corrected substitutions in Table 4;
- corrections in 5.3.14;
- corrections in 5.5.6;
- corrections in 5.17.15;
- corrections in 5.17.16.2;
- spelling and grammar.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 6-3: Spécification du protocole de la couche application - Éléments de type 3

L’IEC 61158-6-3:2019 fournit des éléments communs pour les communications de messagerie prioritaires et non prioritaires élémentaires entre les programmes d’application des environnements d’automatisation et le matériel spécifique au bus de terrain de type 3. Le terme “prioritaire” sert à représenter la présence d’une fenêtre temporelle, dans les limites de laquelle une ou plusieurs actions spécifiées sont tenues d’être parachevées avec un certain niveau défini de certitude. Le manquement à parachever les actions spécifiées dans les limites de la fenêtre temporelle risque d’entraîner la défaillance des applications qui demandent ces actions, avec le risque concomitant pour l’équipement, l’installation et éventuellement pour la vie humaine.
La présente Norme internationale définit de manière abstraite le comportement visible de l’extérieur fourni par la couche application de bus de terrain Type 3 en termes:
a) de syntaxe abstraite définissant les unités de données de protocole de la couche Application, transmises entre les entités d’application en communication;
b) de syntaxe de transfert définissant les unités de données de protocole de la couche Application, transmises entre les entités d’application en communication;
c) de diagramme d’états de contexte d’application définissant le comportement de service d’application observable entre les entités d’application en communication; et
d) de diagrammes d’états de relations d’applications définissant le comportement de communication visible entre les entités d’application en communication.
Le but du présent document est de définir le protocole fourni pour:
a) définir la représentation filaire des primitives de service spécifiées dans l’IEC 61158-5-3, et
b) définir le comportement visible de l’extérieur associé à leur transfert.
Le présent document spécifie le protocole de la couche application des réseaux de terrain de type 3, en conformité avec le Modèle de référence de base de l’OSI (ISO/IEC 7498-1) et la Structure de la couche application de l’OSI (ISO/IEC 9545).
