Industrial communication networks - Fieldbus specifications - Part 6-2: Application layer protocol specification - Type 2 elements
IEC 61158-6-2:2023 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.

L'IEC 61158-6-2:2023 fournit des éléments communs pour les communications prioritaires ou non entre des programmes d’application dans un environnement et avec un matériel d’automatisation spécifiques aux bus de terrain de type 2. Le terme "à temps critique" est utilisé pour indiquer la présence d’une fenêtre temporelle, dans laquelle il est exigé de réaliser une ou plusieurs actions spécifiées selon un niveau défini de certitude. Tout manquement à réaliser ces actions dans la fenêtre de temps prévue risque de provoquer la défaillance des applications qui les demandent, avec le risque de mettre en danger l’équipement, l’usine, voire les personnes.
Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 6-2. del: Specifikacija protokola na aplikacijski ravni - Elementi tipa 2 (IEC 61158-6-2:2023)
Aplikacijska raven procesnih vodil (FAL) uporabniškim programom omogoča dostop do komunikacijskega okolja procesnih vodil. Glede na to je mogoče aplikacijsko raven procesnih vodil šteti za »okno med ustreznimi aplikacijami«.
Ta del standarda IEC 61158 določa skupne elemente za osnovne časovno kritične in časovno nekritične sporočilne komunikacije med aplikacijami v avtomatizacijskem okolju ter material, specifičen 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 dokument opredeljuje interakcije med oddaljenimi aplikacijami in določa na zunaj vidno vedenje, ki ga zagotavlja aplikacijska raven procesnih vodil tipa 2 v smislu:
– formalne abstraktne sintakse, ki določa podatkovne enote protokola aplikacijske ravni, ki se prenašajo med aplikacijskimi osebki, ki komunicirajo;
– prenosne sintakse, ki opredeljuje pravila kodiranja, ki se uporabljajo za podatkovne enote protokola aplikacijske ravni;
– stroja stanja aplikacijskega konteksta, ki opredeljuje vedenje aplikacijskega opravila, vidnega med aplikacijskimi osebki, ki komunicirajo;
– strojev stanja aplikacijskega razmerja, ki opredeljujejo komunikacijsko vedenje med aplikacijskimi osebki, ki komunicirajo.
Namen tega dokumenta je opredeliti protokol, ki se zagotavlja za:
– določitev žične predstavitve primitivov opravil iz standarda IEC 61158-5-2, in
– določitev na zunaj vidnega vedenja, povezanega z njihovim prenosom.
Ta dokument določa protokol aplikacijske ravni procesnih vodil tipa 2 v skladu z osnovnim referenčnim modelom OSI (ISO/IEC 7498-1) in strukturo aplikacijske ravni OSI (ISO/IEC 9545).
