Industrial communication networks - Fieldbus specifications - Part 4-28: Data-link layer protocol specification - Type 28 elements (IEC 61158-4-28:2023)
This document of IEC 61158 describes basic packet communication services and models in an automation control industrial field environment. The Type 28 data-link layer provides time critical and non-time-critical communication services. Time-critical refers to the requirement to complete specified functions between devices in a defined time window in an industrial field environment. Failure to complete specified functions within the time window may lead to failure or harm in industrial production.
This document defines in an abstract way the externally visible service provided by the Type 28 fieldbus data-link layer in terms of
a) function description;
b) primitive actions and events with primitive sequence diagram;
c) the form of externally service interface and related parameters.
The purpose of this document is to define the services provided to:
- the Type 28 fieldbus application layer at the boundary between the application and data link layers of the fieldbus reference model;
- systems management at the boundary between the data-link layer and systems management of the fieldbus reference model.
Type 28 DL-service provides both a connected and a connectionless subset of those services provided by OSI data-link protocols as specified in ISO/IEC 8886.

L’IEC 61158-4-28:2023 fournit un moyen de connexion des appareils par l’intermédiaire d’un réseau maillé partiel, de telle sorte que la plupart des défaillances d’une interconnexion entre deux appareils puissent être contournées. Dans la pratique courante, les appareils sont interconnectés d’une manière hiérarchique non redondante reflétant les besoins de l’application.
Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 4-28. del: Specifikacija protokola na ravni podatkovnih povezav - Elementi tipa 28 (IEC 61158-4-28:2023)
Ta dokument standarda IEC 61158 opisuje osnovna paketna komunikacijska opravila ter modele v industrijskem okolju za avtomatizacijo in nadzor. Raven podatkovne povezave tipa 28 zagotavlja časovno kritična in časovno nekritična komunikacijska opravila. Izraz »časovno kritično« se navezuje na zahtevo po dokončanju opredeljenih funkcij med napravami v določenem časovnem oknu v industrijskem okolju. Zaradi neuspešnega dokončanja opredeljenih funkcij v časovnem oknu lahko pride do odpovedi ali škode v industrijski proizvodnji.
Ta dokument na abstrakten način določa na zunaj vidno opravilo, ki ga zagotavlja podatkovna povezovalna raven procesnih vodil tipa 28 v smislu:
a) opisa funkcije;
b) primitivnih dejanj in dogodkov z diagramom primitivnega zaporedja;
c) oblike vmesnika za zunanja opravila in s tem povezane parametre.
Namen tega dokumenta je opredeliti opravila, ki se zagotavljajo za:
– aplikacijsko raven procesnih vodil tipa 28 na meji med aplikacijsko ravnjo in ravnjo podatkovnih povezav referenčnega modela procesnega vodila;
– upravljanje sistemov na meji med ravnjo podatkovnih povezav in upravljanjem sistemov referenčnega modela procesnega vodila.
Opravilo na ravni podatkovnih povezav tipa 28 zagotavlja podsklop opravil s povezavo in brez povezave, ki jih zagotavljajo protokoli podatkovnih povezav OSI, kot je navedeno v standardu ISO/IEC 8886.
