Industrial communication networks - Fieldbus specifications - Part 6-26: Application layer protocol specification - Type 26 elements

1.1 General The Fieldbus Application Layer (FAL) provides user programs with a means to access the fieldbus communication environment. In this respect, the FAL can be viewed as a "window between corresponding application programs." This part of IEC 61158 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 in terms of a) the formal abstract syntax defining the application layer protocol data units conveyed between communicating application entities; b) the transfer syntax defining encoding rules that are applied to the application layer protocol data units; c) the application context state machine defining the application service behavior visible between communicating application entities; d) the application relationship state machines defining the communication behavior visible between communicating application entities. The purpose of this document is to define the protocol provided to a) define the wire-representation of the service primitives defined in IEC 61158-5-2, 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). 1.2 Specifications The principal objective of this document is to specify the syntax and behavior of the application layer protocol that conveys the application layer services defined in IEC 61158-5-2. A secondary objective is to provide migration paths from previously-existing industrial communications protocols. 1.3 Conformance This document does not specify individual implementations or products, nor does it constrain the implementations of application layer entities within industrial automation systems. Conformance is achieved through implementation of this application layer protocol specification.

L'IEC 61158-6-26:2023 donne les éléments communs visant à assurer les communications de messagerie de base à temps critique et à temps non critique entre les programmes d’application d’un environnement d’automatisation et d’un matériel spécifique au bus de terrain de type 26. 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 - 6-26. del: Specifikacija protokola na aplikacijski ravni - Elementi tipa 26 (IEC 61158-6-26:2023)

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 mednarodni standard opredeljuje interakcije med oddaljenimi aplikacijami in določa na zunaj vidno vedenje, ki ga zagotavlja aplikacijska raven procesnih vodil tipa 2 v smislu:
a) formalne abstraktne sintakse, ki določa podatkovne enote protokola aplikacijske ravni, ki se prenašajo med aplikacijskimi osebki, ki komunicirajo;
b) prenosne sintakse, ki opredeljuje pravila kodiranja, ki se uporabljajo za podatkovne enote protokola aplikacijske ravni;
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 dokumenta je opredeliti protokol, ki se zagotavlja za:
a) določitev žične predstavitve primitivov opravil iz standarda IEC 61158-5-2, in
b) 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).
