Industrial communication networks - Fieldbus specifications - Part 6-23: Application layer protocol specification - Type 23 elements

IEC 61158-6-23:2019 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 second edition includes the following significant technical changes with respect to the previous edition: - addition of the transmission extended mode and related attribute (Clauses 3.2.28, 4.1.9, 4.4, 5.2.9.2, and 5.3); - update of Table 4, Table 5, Table 16 and Table 48.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 6-23: Spécification du protocole de la couche application - Eléments de type 23

L’IEC 61158-6-23:2019 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 23. On utilise le terme "prioritaire" pour traduire la présence d’une fenêtre temporelle, à l’intérieur de laquelle il est exigé qu’une ou plusieurs actions spécifiées soient terminées avec un niveau de certitude défini. Si les actions spécifiées ne sont pas réalisées dans la fenêtre temporelle, les applications demandant les actions risquent de connaître une défaillance, avec les risques que cela comporte pour les équipements, les installations et éventuellement la vie humaine. Le présent document vise à définir le protocole mis en place pour: a) définir la représentation câblée des primitives de service définies dans l’IEC 61158 5 23, et b) définir le comportement visible de l’extérieur associé à leur transfert.

Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 6-23. del: Specifikacija protokola na aplikacijski ravni - Elementi tipa 23 (IEC 61158-6-23:2019)

Ta dokument določa skupne elemente za osnovne časovno kritične in časovno nekritične sporočilne komunikacije med aplikacijami v avtomatizacijskem okolju ter materialu, specifičnem za procesna vodila tipa 23. 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 na abstrakten način določa zunanje vidno vedenje, ki ga zagotavljajo različni tipi aplikacijskega nivoja procesnih vodil v zvezi s/z: a) abstraktno sintakso, ki opredeljuje podatkovne enote protokola aplikacijskega nivoja, ki se prenašajo med aplikacijskimi osebki, ki komunicirajo, b) prenosno sintakso, ki opredeljuje podatkovne enote protokola aplikacijskega nivoja, ki se prenašajo med aplikacijskimi osebki, ki komunicirajo, 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 61158-5-23 in b) določitev zunanje vidnega vedenja, povezanega z njihovim prenosom. Ta dokument določa protokol aplikacijskega nivoja procesnih vodil IEC v skladu z osnovnim referenčnim modelom OSI (ISO/IEC 7498) in strukturo aplikacijskega nivoja OSI (ISO/IEC 9545). Opravila in protokole aplikacijskega nivoja procesnih vodil zagotavljajo aplikacijski osebki (AE) aplikacijskega nivoja procesnih vodil znotraj aplikacijskih procesov. Aplikacijski osebek aplikacijskega nivoja procesnih vodil sestavljata sklop objektno usmerjenih aplikacijskih opravilnih elementov (ASE) in osebek za upravljanje nivojev (LME), ki upravlja aplikacijski osebek. Aplikacijski opravilni elementi zagotavljajo komunikacijska opravila, ki delujejo na sklopu povezanih razredov objektov aplikacijskega procesa (APO). Med aplikacijske opravilne elemente aplikacijskega nivoja procesnih vodil spada aplikacijski opravilni element za upravljanje, ki zagotavlja skupen sklop opravil za upravljanje primerkov razredov aplikacijskega nivoja procesnih vodil. Čeprav ta opravila določajo način izdajanja ter dostavljanja zahtev in odzivov z vidika aplikacij, ne zajemajo specifikacije v zvezi s tem, kako naj se nanje odzovejo aplikacije, ki te zahteve in odzive oddajajo. To pomeni, da vedenjski vidiki aplikacij niso opredeljeni; opredeljena je le definicija zahtev in odzivov, ki jih lahko pošiljajo/prejemajo. Tako se uporabnikom aplikacijskega nivoja procesnih vodil omogoči večja prilagodljivost pri standardizaciji takega vedenja objektov. Poleg teh opravil so v tem dokumentu opredeljena tudi nekatera podporna opravila, da se omogoči dostop do aplikacijskega nivoja procesnih vodil za nadzorovanje nekaterih vidikov njegovega delovanja.
