Industrial communication networks - Fieldbus specifications - Part 5-26: Application layer service definition - 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 defines in an abstract way the externally visible service provided by the Type 2 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 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). 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 318 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. 1.2 Specifications [...] 1.3 Conformance [...]

L'IEC 61158-5-26:2023 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 26. Le terme "prioritaire" signale l’existence d’une fenêtre temporelle dans laquelle une ou plusieurs actions spécifiées doivent être réalisées, avec un niveau de certitude défini. Si les actions spécifiées ne sont pas réalisées dans la fenêtre temporelle, les demandes d’action risquent d’être rejetées, avec les risques que cela comporte pour les équipements, les installations et éventuellement la vie humaine. Le présent document définit de manière abstraite le service, visible par un observateur extérieur, assuré par la couche application de bus de terrain de type 26, en matière: de modèle abstrait visant à la définition des ressources d’application (objets) qui peuvent être manipulées par des utilisateurs utilisant un service FAL; d’événements et d’actions liés aux primitives du service; de paramètres associés à chaque événement et action de primitive, ainsi que de forme prise par ces paramètres; et d’interaction entre ces événements et ces actions, ainsi que de séquences valides desdits événements et actions.
Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 5-26. del: Definicija opravil na aplikacijski ravni - Elementi tipa 26 (IEC 61158-5-26:2023)
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 na abstrakten način določa na zunaj vidno opravilo, ki ga zagotavlja aplikacijska raven procesnih vodil tipa 2 v smislu:
a) abstraktnega modela za določanje aplikacijskih virov (objektov), ki ga lahko upravljajo uporabniki prek opravila aplikacijske ravni procesnih vodil,
b) primitivnih dejanj in dogodkov opravila;
c) parametrov, povezanih z vsakim primitivnim dejanjem in dogodkom, ter obliko, ki jo prevzamejo; in
d) medsebojne povezave med temi dejanji in dogodki ter njihovimi veljavnimi zaporedji.
Namen tega dokumenta je opredeliti opravila, ki se zagotavljajo za:
a) uporabnika aplikacijske ravni procesnih vodil na meji med uporabniško in aplikacijsko ravnjo referenčnega modela procesnega vodila, in
b) upravljanje sistemov na meji med aplikacijsko ravnjo in upravljanjem sistemov za referenčni model procesnega vodila.
Ta dokument določa strukturo in opravila aplikacijske ravni procesnih vodil tipa 2 v skladu z osnovnim referenčnim modelom OSI (ISO/IEC 7498-1) ter strukturo aplikacijske ravni OSI (ISO/IEC 9545).
Opravila in protokole aplikacijske ravni procesnih vodil zagotavljajo aplikacijski osebki (AE) aplikacijske ravni procesnih vodil znotraj aplikacijskih procesov. Aplikacijski osebek aplikacijske ravni procesnih vodil sestavljata sklop objektno usmerjenih aplikacijskih opravilnih elementov (ASE) in osebek za upravljanje ravni (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 aplikacijske ravni procesnih vodil spada aplikacijski opravilni element za upravljanje, ki zagotavlja skupen sklop opravil za upravljanje primerkov razredov aplikacijske ravni 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 318 uporabnikom aplikacijske ravni 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 aplikacijske ravni procesnih vodil za nadzorovanje nekaterih vidikov njenega delovanja.
