Industrial communication networks - Fieldbus specifications - Part 3-25: Data-link layer service definition - Type 25 elements

IEC 61158-3-25:2019 defines the services provided to the Type 25 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model and systems management at the boundary between the data-link layer and systems management of the fieldbus reference model. It provides common elements for basic time-critical messaging communications between devices in an automation environment.

L'IEC 61158-3-25:2019 fournit les éléments communs des communications de messagerie prioritaires de base entre dispositifs dans un environnement automatisé. On utilise le terme "prioritaire" pour traduire la présence d’une fenêtre temporelle, à l’intérieur de laquelle une ou plusieurs actions spécifiées doivent être 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 - 3-25 del: Definicija opravil na ravni podatkovne povezave - Elementi tipa 25 (IEC 61158-3-25:2019)

Ta dokument določa skupne elemente za osnovne časovno kritične sporočilne komunikacije med napravami v avtomatizacijskem okolju. 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 nivo podatkovnih povezav procesnih vodil tipa 25 v zvezi s/z: a) primitivnimi dejanji in dogodki opravila; b) parametri, povezanimi z vsakim primitivnim dejanjem in dogodkom, ter obliko, ki jo prevzamejo; in c) medsebojno povezavo med temi dejanji in dogodki ter njihovimi veljavnimi zaporedji. Namen tega dokumenta je opredeliti opravila, ki se zagotavljajo za: – aplikacijski nivo procesnih vodil tipa 25 na meji med aplikacijskim nivojem in nivojem podatkovnih povezav referenčnega modela procesnih vodil; – vodenje sistemov na meji med nivojem podatkovnih povezav in vodenje sistemov referenčnega modela procesnih vodil.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that t
