EN 61158-6-2:2014

Industrial communication networks - Fieldbus specifications - Part 6-2: Application layer protocol specification - Type 2 elements

IEC 61158-6-2:2014 defines the protocol provided to define the wire-representation of the service primitives defined in IEC 61158-5-2, and define the externally visible behavior associated with their transfer. This standard 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 third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. The main changes are: - Updates of definition used by the Time Sync object; - Addition of "member" and object specific services in 4.1.2.1, 4.1.8, 4.1.10, 8.2; - Removal of obsolete transport classes 4 to 6 in 4.1.4.6, and 9.3.9 to 9.3.12; - Clarification of transport header formats in 4.1.4; - Update of CM and MR PDUs in 4.1.5 to 4.1.7; - Updates of Identity object PDUs in 4.1.8.2; - Updates of Assembly object PDUs in 4.1.8.4; - Updates of Time sync object PDUs in 4.1.8.6; - Updates of Parameter object PDUs in 4.1.8.7; - Updates of Connection Manager object PDUs in 4.1.8.8; - Updates of message and connection paths in 4.1.9; - Updates of object class codes in 4.1.10 and error codes in 4.1.11; - Updates of data types in 4.2.4 and 5.2.3; - Updates of the encapsulation abstract syntax in 4.3; - Updates to the DLL mapping protocol machine 2 in Clause 11.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 6-2: Spécification du protocole de la couche application - Éléments de type 2

L'IEC 61158-6-2:2014 décrit le protocole mis en place pour définir la représentation filaire des primitives de service définies dans la CEI 61158-5-2 et définir le comportement visible de l'extérieur associé à leur transfert. La présente norme spécifie le protocole de la couche application de bus de terrain de Type 2, en conformité avec le modèle de référence de base OSI (ISO/CEI 7498-1) et la structure de la couche application OSI (ISO/CEI 9545). Cette troisième édition annule et remplace la deuxième édition parue en 2010. Elle constitue une révision technique. Les principales modifications par rapport à l'édition précédente sont les suivantes: - mise à jour des définitions utilisées par l'objet Time Sync; - ajout de "membre" et des services spécifiques à un objet en 4.1.2.1, 4.1.8, 4.1.10, 8.2; - suppression des classes de transport obsolètes 4 à 6 en 4.1.4.6 et de 9.3.9 à 9.3.12; - clarification des formats d'en-tête de transport en 4.1.4; - mise à jour du CM et des PDU de MR de 4.1.5 à 4.1.7; - mise à jour des PDU de l'objet Identity en 4.1.8.2; - mise à jour des PDU de l'objet Assembly en 4.1.8.4; - mise à jour des PDU de l'objet Time Sync en 4.1.8.6; - mise à jour des PDU de l'objet Parameter en 4.1.8.7; - mise à jour des PDU de l'objet Connection Manager en 4.1.8.8; - mise à jour des chemins de message et de connexion en 4.1.9; - mise à jour des codes de classe d'objet en 4.1.10 et des codes d'erreur en 4.1.11; - mise à jour des types de données en 4.2.4 et 5.2.3; - mise à jour de la syntaxe abstraite d'encapsulation en 4.3; - mise à jour du diagramme protocolaire de mapping DLL 2 à l'Article 11.

Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 6-2. del: Specifikacija protokola na aplikacijski ravni - Elementi tipa 2 (IEC 61158-6-2:2014)

1.1 General
Aplikacijski nivo procesnih vodil (FAL) omogoča uporabniškim programom dostop do komunikacijskega okolja procesnih vodil. Glede na to je mogoče aplikacijski nivo procesnih vodil obravnavati kot »okno med ustreznimi aplikacijami«.
Ta standard določa skupne elemente za osnovne časovno kritične in časovno nekritične sporočilne komunikacije med aplikacijami v avtomatizacijskem okolju in materialu, specifičnem za procesna vodila tipa 2. Izraz »časovno kritičen« se uporablja za predstavitev prisotnosti časovnega okna, v okviru katerega se zahteva dokončanje enega ali več opredeljenih dejanj z določeno stopnjo gotovosti. Zaradi neuspešnega dokončanja opredeljenih dejanj v časovnem oknu je možna odpoved aplikacij, ki zahtevajo dejanja, pri čemer so ogroženi oprema, obrat in morda človeška življenja.
Ta standard opredeljuje interakcije med oddaljenimi aplikacijami in določa zunanje vidno vedenje, ki ga zagotavlja aplikacijski nivo procesnih vodil tipa 2 v smislu
a) formalne abstraktne sintakse, ki določa podatkovne enote protokola aplikacijskega nivoja, ki se prenašajo med aplikacijskimi osebki, ki komunicirajo;
b) prenosne sintakse, ki opredeljuje pravila kodiranja, ki se uporabljajo za podatkovne enote protokola aplikacijskega nivoja;
c) stroja stanja aplikacijskega konteksta, ki opredeljuje vedenje aplikacijskega opravila, vidnega med aplikacijskimi osebki, ki komunicirajo;
d) strojev stanja aplikacijskega razmerja, ki opredeljujejo komunikacijsko vedenje med aplikacijskimi osebki, ki komunicirajo.
Namen tega standarda je opredeliti protokol, ki se zagotavlja za
a) določitev žične predstavitve primitivov opravil iz standarda IEC 61158-5-2, in
b) določitev zunanje vidnega vedenja, povezanega z njihovim prenosom.
Ta standard določa protokol aplikacijskega nivoja procesnih vodil tipa 2 v skladu z osnovnim referenčnim modelom OSI (ISO/IEC 7498-1) in strukturo aplikacijskega nivoja OSI (ISO/IEC 9545).
