Industrial communication networks - Fieldbus specifications - Part 5-23: Application layer service definition - Type 23 elements

IEC 61158-5-25:2023 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 23 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.

L'IEC 61158-5-25:2023 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 23. 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 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 61158-5-23:2023)

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 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 dokument na abstrakten način določa na zunaj vidno opravilo, ki ga zagotavlja aplikacijska raven procesnih vodil različnih tipov 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 IEC 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 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.
