IEC 61158-1:2010(E) presents an overview and guidance for the IEC 61158 series by: - explaining the structure and content of the IEC 61158 series; - relating the structure of the IEC 61158 series to the ISO/IEC 7498 OSI Basic Reference Model; - showing the logical structure of the IEC 61784 series; - showing how to use parts of the IEC 61158 series in combination with the IEC 61784 series; - providing explanations of some aspects of the IEC 61158 series that are common to the parts of the IEC 61158-5 series. This third edition cancels and replaces the second edition published in 2007 and constitutes a technical revision. It includes the following significant changes with respect to the previous edition: - Updates of the references to the IEC 61158 series, IEC 61784-1, IEC 61784-3, IEC 61784-5 series and IEC 61918 throughout the document; - new Type 21 and the related profile family CPF 17; - new Type 22 and the related profile family CPF 18.

presents an overview and guidance for the IEC 61158 series. It explains the structure and content of the IEC 61158 series; relates the structure of the IEC 61158 series to the ISO/IEC 7498 OSI Basic Reference Model; shows the logical structure of the IEC 61784 series; shows how to use parts of the IEC 61158 series in combination with IEC 61784 series; provides explanations of some aspects of the IEC 61158 series that are common to the parts of the IEC 61158 5 series. It includes the following significant changes from the previous edition: deletion of the former Type 6 fieldbus, a placeholder for a Type 5 fieldbus data-link layer, and the Type 1 application layer for lack of market relevance; addition of new types of fieldbuses: types 11 to 20; generalization of the Type 1 radio, which is seldom used, to a more useful form; additional descriptions explaining the relation of IEC 61158 to the IEC 61784 family of companion profiles and the structure of these profile documents; division of parts 3 through 6 of the third edition into multiple parts numbered 3 1, 3 2, , 3 19; 4 1, 4 2, , 4 19; 5 2, 5 3, , 5 20; 6 2, 6 3, , 6 20; presentation of the service description concepts used in the many application layer service definitions: parts 5 2, 5 3, , 5 20.

IEC 61158-1:2019 specifies the generic concept of fieldbuses. This document presents an overview and guidance for the IEC 61158 series explaining the structure and content of the IEC 61158 series, relating the structure of the IEC 61158 series to the ISO/IEC 7498-1 OSI Basic Reference Model and showing how to use parts of the IEC 61158 series in combination with the IEC 61784 series. It also provides explanations of some aspects of the IEC 61158 series that are common to the type specific parts of the IEC 61158 5 including the application layer service description concepts and the generic fieldbus data types.
