Industrial communication networks - Fieldbus specifications - Part 5-4: Application layer service definition - Type 4 elements

IEC 61158-5-4:2019 (E) defines the services provided to the FAL user at the boundary between the user and the application layer of the fieldbus reference model, and Systems Management at the boundary between the application layer and Systems Management of the fieldbus reference model. This standard 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). This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) additional user parameters to services; b) additional services to support distributed objects; c) additional secure services.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 5-4 : Définition des services de la couche application - Éléments de type 4

L’IEC 61158-5-4:2019 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 4. 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. La présente norme définit de manière abstraite le service visible de l'extérieur fourni par la couche application de bus de terrain de type 4 en termes a) d’un modèle abstrait pour la définition des ressources d’application (objets) qui peuvent être manipulées par les utilisateurs par l'intermédiaire de l’utilisation du service FAL, b) des actions primitives et des événements du service; c) des paramètres associés à chaque action et événement primitif, et de la forme qu’ils peuvent prendre; et d) des interrelations entre ces actions et événements, et de leurs séquences valides.

Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 5-4. del: Definicija opravil na aplikacijski ravni - Elementi tipa 4 (IEC 61158-5-4:2019)

Aplikacijski nivo procesnih vodil (FAL) uporabniškim programom omogoča dostop do komunikacijskega okolja procesnih vodil. Glede na to je mogoče aplikacijski nivo 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 4. 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 zagotavlja aplikacijski nivo procesnih vodil tipa 4 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: 1) uporabnika aplikacijskega nivoja procesnih vodil na meji med uporabnikom in aplikacijskim nivojem referenčnega modela procesnih vodil ter 2) upravljanje sistemov na meji med aplikacijskim nivojem in upravljanje sistemov referenčnega modela procesnih vodil. Ta dokument določa strukturo in opravila aplikacijskega nivoja procesnih vodil tipa 4 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.
