Industrial communication networks - Fieldbus specifications - Part 5-21: Application layer service definition - Type 21 elements

IEC 61158-5-21:2010 specifies the structure and services of the type 21 IEC fieldbus Application Layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498) and the OSI Application Layer Structure (ISO/IEC 9545). This standard cancels and replaces IEC/PAS 62573 published in 2008. This bilingual version published in 2012-01 corresponds to the English version published in 2010-08.

La CEI 61158-5-21:2010 spécifie la structure et les services de la couche application des bus de terrain de Type 21, en conformité avec le Modèle de référence de base de l'OSI (ISO/CEI 7498-1) et la structure de la couche application de l'OSI (ISO/CEI 9545). La présente norme annule et remplace IEC/PAS 62573 publiée en 2008 et constitue une révision technique. La présente version bilingue publiée en 2012-01 correspond à la version anglaise monolingue publiée en 2010-08.

Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 5-21. del: Definicija opravil na aplikacijskem nivoju - Elementi tipa 21 (IEC 61158-5-21:2010)

Aplikacijski nivo procesnih vodil (FAL) omogoča uporabniškim programom dostop do komunikacijskega okolja procesnih vodil. Glede na to je mogoče aplikacijski nivo procesnih vodil šteti za »okno med ustreznimi aplikacijami«. Ta standard določa skupne elemente za osnovne časovno kritične in časovno nekritične sporočilne komunikacije med aplikacijami v avtomatizacijskem okolju in material, specifičen za protokol tipa 21. 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.
