Industrial communication networks - Fieldbus specifications - Part 3-20: Data-link layer service definition - Type 20 elements
IEC 61158-3-20:2014 defines the services provided to the Type 20 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. Type 20 DL-service provides both a connected and a connectionless subset of those services specified in ISO/IEC 8886.

Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 3-20. del: Specifikacija protokola na ravni podatkovnih povezav - Elementi tipa 20 (IEC 61158-3-20:2014)
Ta mednarodni standard 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 standard na abstrakten način določa na zunaj vidno opravilo, ki ga zagotavlja podatkovna povezovalna raven procesnih vodil tipa 20 v smislu
a) preprostih dejanj in dogodkov opravila;
b) parametrov, povezanih z vsakim preprostim dejanjem in dogodkom, ter obliko, ki jo prevzamejo; in
c) medsebojnih povezav med temi dejanji in dogodki ter njihovimi veljavnimi zaporedji.
Namen tega standarda je opredeliti opravila, ki se zagotavljajo za:
• aplikacijsko raven procesnih vodil tipa 20 na meji med aplikacijo in podatkovno povezovalno ravnjo referenčnega modela procesnega vodila;
• upravljanje sistemov na meji med podatkovno povezovalno ravnjo in upravljanjem sistemov referenčnega modela procesnega vodila.
Protokol na ravni podatkovnih povezav tipa 20 zagotavlja podsklop povezljivih storitev in storitev brez povezave, ki so opisane v standardu ISO/IEC 8886.
1.2 Specifikacija
Glavni cilj tega standarda je določiti značilnosti konceptualnih opravil nivoja podatkovnih povezav, primernih za časovno kritične komunikacije, ter tako dopolniti osnovni referenčni model OSI pri usmerjanju razvoja protokolov časovnih povezav za časovno kritične komunikacije. Drugotni cilj je zagotoviti načrte prehoda iz predhodno obstoječih industrijskih komunikacijskih protokolov. Ta specifikacija se lahko uporablja kot podlaga za formalne programske vmesnike podatkovne povezave. Vseeno ne gre za formalni programski vmesnik, pri čemer mora vsak tak vmesnik obravnavati izvedbena vprašanja, ki jih ta specifikacija ne zajema, vključno z:
a) velikostmi in oktetnim naročanjem različnih večoktetnih parametrov opravil;
b) korelacijo parnih primitivov za zahtevo in potrjevanje ali navedbo in odziv.
1.3 Skladnost
Ta standard ne določa posameznih implementacij ali izdelkov ter ne omejuje implementacije entitet podatkovnih povezav v okviru sistemov za industrijsko avtomatizacijo. Ta oprema ni skladna s standardom za specifikacijo protokola na ravni podatkovnih povezav. Skladnost se doseže prek implementacije ustreznega protokola podatkovnih povezav, ki izpolnjuje storitve ravni podatkovnih povezav tipa 20, ki je določen v tem standardu.

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 Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
Attention is drawn to the fact that the use of the associated protocol type is restricted by its
