Industrial communication networks - Fieldbus specifications - Part 4-21: Data-link layer protocol specification - Type 21 elements
IEC 61158-4-21:2010 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 and procedures for giving communication opportunities based on standard ISO/IEC 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 standard, and their representation as physical interface data units. 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 61158-4-21:2010 décrit des procédures de transfert en temps opportun de données et d'informations de commande d'une entité utilisateur de liaison de données à une entité utilisateur homologue ainsi qu'entre entités de liaison de données qui constituent le fournisseur de services distribués de la liaison; des procédures offrant des moyens de communication fondées sur le MAC de l'ISO/CEI 8802-3, ainsi que des dispositions permettant d'ajouter et de retirer des noeuds au cours du fonctionnement normal; la structure des unités de données de protocole de liaison de données (DLPDU) de bus de terrain utilisées pour le transfert des données et les informations de commande par le protocole objet de la présente norme, ainsi que leur représentation en tant qu'unité de données d'interface de couche physique. La présente norme annule et remplace la CEI/PAS 62573 publiée en 2008. 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 - 4-21. del: Specifikacija protokola na nivoju podatkovnih povezav - Elementi tipa 21 (IEC 61158-4-21:2010)
Nivo podatkovnih povezav omogoča osnovne časovno kritične podatkovne komunikacije med napravami v avtomatiziranem okolju. Tip 21 omogoča prioritetno ciklično in aciklično podatkovno komunikacijo z notranjo tehnologijo preklopa Ethernet brez kolizije, z dvojnimi vrati za popolno dupleksiranje. Za široko uporabo na različnih področjih avtomatizacije tip 21 ne omejuje politike cikličnega/acikličnega razporejanja na nivoju podatkovnih povezav.
