Industrijska komunikacijska omrežja - Specifikacije za procesno vodilo - 5-20. del: Definicija opravil na aplikacijskem nivoju - Elementi tipa 20 (IEC 61158-5-20:2010)
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 del standarda IEC 61158 določa skupne elemente za osnovne časovno kritične in časovno nekritične sporočilne komunikacije med aplikacijami v avtomatizacijskem okolju in material, specifičen za procesna vodila tipa 20. 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 standard na abstrakten način določa zunanje vidno opravilo, ki ga zagotavljajo različni tipi aplikacijskih nivojev procesnih vodil v zvezi 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, in obliko, ki jo prevzamejo; ter d) medsebojno povezavo med temi dejanji in dogodki ter njihovimi veljavnimi zaporedji. Namen tega standarda je opredeliti opravila, ki se zagotavljajo za a) uporabnika aplikacijskega nivoja procesnih vodil na meji med uporabnikom in aplikacijskim nivojem referenčnega modela procesnih vodil ter b) upravljanje sistemov na meji med aplikacijskim nivojem in upravljanje 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 the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publication
