Industrial communication networks - Fieldbus specifications - Part 6-18: Application layer protocol specification - Type 18 elements

IEC 61158-6-18:2010(E) specifies the protocol of the Type 18 fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application layer structure (ISO/IEC 9545). It defines the protocol provided to define the wire-representation of the service primitives defined in IEC 61158-5-18:2010, and the externally visible behavior associated with their transfer. This second edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. The main changes with respect to the previous edition are: - editorial corrections; - addition of cyclic data segmenting.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 6-18: Spécification des protocoles des couches d'application - Eléments de type 18

L'IEC 61158-6-18:2010 fournit des éléments communs pour les communications en temps critique ou non entre des programmes d'application dans un environnement et avec un matériel d'automatisation propres aux bus de terrain de type 18. Le terme "en temps critique" signale l'existence d'une fenêtre temporelle dans laquelle est exigée la réalisation d'une ou de plusieurs actions spécifiées, avec un niveau de certitude défini. La non-réalisation des actions spécifiées dans la fenêtre temporelle induit un risque de défaillance des applications qui exigent ces actions, avec les risques afférents pour l'équipement, les installations et éventuellement la vie humaine. La présente norme définit les interactions entre les applications distantes ainsi que le comportement, visible par un observateur externe, assuré par la couche Application de bus de terrain de type 18, en termes a) de syntaxe abstraite formelle définissant les unités de données de protocole de couche application, acheminées entre les entités d'application en communication; b) de syntaxe de transfert définissant les règles de codage qui s'appliquent aux unités de données de protocole de couche application; c) de la machine à état de contexte application définissant le comportement de service application visible entre des entités d'application engagées dans une communication; d) de machines à état de relations d'applications définissant le comportement de communication visible entre les entités d'application en communication.

Industrijska komunikacijska omrežja - Specifikacije za procesno vodilo - 6-18. del: Specifikacija protokola na aplikacijskem nivoju - Elementi tipa 18 (IEC 61158-6-18:2010)

Aplikacijski nivo procesnih vodil (FAL) omogoča uporabniškim programom dostop do komunikacijskega okolja procesnih vodil. Glede na to je mogoče aplikacijski nivo procesnih vodil šteti za »okno med ustreznimi aplikacijami«. Ta standard določa skupne elemente za osnovne časovno kritične in časovno nekritične sporočilne komunikacije med aplikacijami v avtomatizacijskem okolju in material, specifičen za procesna vodila tipa 18. 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 18 v zvezi z a) formalno abstraktno sintakso, ki opredeljuje podatkovne enote protokola aplikacijskega nivoja, ki se prenašajo med aplikacijskimi osebki, ki komunicirajo, b) prenosno sintakso, ki opredeljuje pravila kodiranja, ki se uporabljajo za podatkovne enote protokola aplikacijskega nivoja, c) strojem stanj aplikacijskega konteksta, ki opredeljuje vedenje aplikacijskega opravila, vidnega med aplikacijskimi osebki, ki komunicirajo, in d) stroji stanj aplikacijskega razmerja, ki opredeljujejo komunikacijsko vedenje med aplikacijskimi osebki, ki komunicirajo. Namen tega standarda je opredeliti protokol za a) določitev žične predstavitve primitivov opravil iz standarda IEC 61158-5-18 in b) določitev zunanje vidnega vedenja, povezanega z njihovim prenosom. Ta standard določa protokol aplikacijskega nivoja procesnih vodil tipa 18 v skladu z osnovnim referenčnim modelom OSI (ISO/IEC 7498-1) in strukturo aplikacijskega nivoja OSI (ISO/IEC 9545).
