Industrial communication networks - Fieldbus specifications - Part 5-23: Application layer service definition - Type 23 elements (IEC 61158-5-23:2019)
This document provides common elements for basic time-critical and non-time-critical messaging communications between in an automation environment and material specific to Type 12 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 defines in an abstract way the externally visible service provided by the different Types of the fieldbus Application Layer in terms of a) an abstract model for defining application resources (objects) capable of being manipulated by users via the use of the FAL service, b) the primitive actions and events of the service; c) the parameters associated with each primitive action and event, and the form which they take; and d) the interrelationship between these actions and events, and their valid sequences. The purpose of this document is to define the services provided to a) the FAL user at the boundary between the user and the Application Layer of the Fieldbus Reference Model, and b) Systems Management at the boundary between the Application Layer and Systems Management of the Fieldbus Reference Model. This document specifies the structure and services of the IEC Fieldbus Application Layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI Application Layer Structure (ISO/IEC 9545). FAL services and protocols are provided by FAL application-entities (AE) contained within the application processes. The FAL AE is composed of a set of object-oriented Application Service Elements (ASEs) and a Layer Management Entity (LME) that manages the AE. The ASEs provide communication services that operate on a set of related application process object (APO) classes. One of the FAL ASEs is a management ASE that provides a common set of services for the management of the instances of FAL classes. Although these services specify, from the perspective of applications, how request and responses are issued and delivered, they do not include a specification of what the requesting and responding applications are to do with them. That is, the behavioral aspects of the applications are not specified; only a definition of what requests and responses they can send/receive is specified. This permits greater flexibility to the FAL users in standardizing such object behavior. In addition to these services, some supporting services are also defined in this document to provide access to the FAL to control certain aspects of its operation.

L’IEC 61158-5-23:2019 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 12. 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.
Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 5-23. del: Definicija opravil na aplikacijski ravni - Elementi tipa 23 (IEC 61158-5-23:2019)
Ta dokument določa skupne elemente za osnovne časovno kritične in časovno nekritične sporočilne komunikacije v avtomatizacijskem okolju ter materialu, specifičnem za procesna vodila tipa 12. 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 opravilo, ki ga zagotavljajo različni tipi aplikacijskih nivojev procesnih vodil v zvezi s/z: a) abstraktnim modelom za določanje aplikacijskih virov (objektov), ki jih uporabniki lahko spreminjajo prek opravila aplikacijskega nivoja procesnih vodil; b) primitivnimi dejanji in dogodki opravila; c) parametri, povezanimi z vsakim primitivnim dejanjem in dogodkom, kot tudi obliko, ki jo prevzamejo; ter d) medsebojno povezavo med temi dejanji in dogodki ter njihovimi veljavnimi zaporedji. Namen tega dokumenta je opredeliti opravila, ki se zagotavljajo za: a) uporabnika aplikacijskega nivoja procesnih vodil na meji med uporabnikom in aplikacijskim nivojem referenčnega modela procesnih vodil ter b) upravljanje sistemov na meji med aplikacijskim nivojem in upravljanje sistemov referenčnega modela procesnih vodil. Ta dokument določa strukturo in opravila aplikacijskega nivoja procesnih vodil IEC v skladu z osnovnim referenčnim modelom OSI (ISO/IEC 7498-1) ter 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.
