Industrial communication networks - Fieldbus specifications - Part 6-21: Application layer protocol specification - Type 21 elements

IEC 61158-6-21:2019 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 2 fieldbus. The term “time-critical” is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life. This International Standard specifies interactions between remote applications and defines the externally visible behavior provided by the Type 2 fieldbus application layer. The purpose of this document is to define the protocol provided to a) define the wire-representation of the service primitives defined in this document, and b) define the externally visible behavior associated with their transfer. This document specifies the protocol of the Type 2 fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application layer structure (ISO/IEC 9545). This second edition includes the following significant technical changes with respect to the previous edition: - added WriteAndRead service; - miscellaneous editorial corrections.

L’IEC 61158-6-21:2019 appartient à une série élaborée pour faciliter l’interconnexion des composants des systèmes d’automatisation. Elle est liée à d'autres normes de la série telle que définie par le modèle de référence des bus de terrain "à trois couches" décrit dans l’IEC 61158‑1. La présente Norme internationale contient des éléments spécifiques au protocole de communication de Type 21.

Ta dokument spada v skupino standardov, namenjenih za lažje medsebojno povezovanje sestavnih delov avtomatizacijskega sistema. Povezan je z drugimi standardi v sklopu, kakor je opredeljeno s trinivojskim referenčnim modelom procesnih vodil iz standarda IEC 61158-1. Ta mednarodni standard vsebuje material, specifičen za komunikacijski protokol tipa 21.
