Industrial communication networks - Fieldbus specifications - Part 4-21: Data-link layer protocol specification - Type 21 elements
IEC 61158-4-21:2023 describes: procedures for the timely transfer of data and control information from one data link user entity to a peer user entity, and among the data link entities forming the distributed data link service provider; procedures for giving communication opportunities based on ISO/IEC/IEEE 8802‑3 MAC, with provisions for nodes to be added or removed during normal operation; structure of the fieldbus data link protocol data units (DLPDUs) used for the transfer of data and control information by the protocol of this document, and their representation as physical interface data units.

Standard IEC 61158-4-21:2023 opisuje:
• postopke za pravočasen prenos podatkov in informacij o nadzoru od ene entitete s podatkovno povezavo do entitete vrstnikov ter med entitetami s podatkovno povezavo, ki tvorijo ponudnika porazdeljenih opravil podatkovne povezave;
• postopke za omogočanje komunikacijskih priložnosti na podlagi nadzora dostopa do medija (MAC) iz standarda ISO/IEC/IEEE 8802‑3 z možnostjo dodajanja ali odstranjevanja vozlišč med običajnim delovanjem;
• strukturo podatkovnih enot protokola podatkovnih povezav (DLPDU) za procesna vodila, ki se uporabljajo za prenos podatkov in informacij o nadzoru s protokolom tega standarda, in njihovo zastopanost v obliki podatkovnih enot fizičnega vmesnika.
