Overview
EN IEC 61158-1:2023 - titled Industrial communication networks - Fieldbus specifications - Part 1: Overview and guidance for the IEC 61158 and IEC 61784 series - specifies the generic concept of fieldbuses and provides high‑level guidance for using the IEC 61158 and IEC 61784 families. The document explains the structure and content of the IEC 61158 series, maps that structure to the ISO/IEC 7498-1 OSI Basic Reference Model, and clarifies how to combine IEC 61158 parts with IEC 61784 profiles. It also summarizes common concepts such as application layer service descriptions and generic fieldbus data types.
Key topics
- Fieldbus concept and structure: Generic architecture and the logical layering used across fieldbus types.
- OSI mapping: Relationship of IEC 61158 components to the OSI Basic Reference Model (physical, data‑link, application layers).
- Physical, data‑link and application layer guidance: Overviews of services, protocols and media characteristics for many fieldbus types.
- Application layer service description concepts: Naming, addressing, application processes, objects and service elements.
- Profiles and interoperability: How to use IEC 61158 parts together with IEC 61784 fieldbus, safety and installation profiles.
- Guidance for implementers: Supported options, benefits of a common formal style, and practical implementation advice.
- Summaries and comparisons: Characteristic summaries for physical, data‑link and application layers by fieldbus type.
Applications and who uses it
EN IEC 61158-1:2023 is essential for:
- Automation and control engineers designing or integrating fieldbus‑based industrial networks.
- System integrators and OEMs implementing compliant communication stacks and ensuring interoperability.
- Network architects choosing media, protocols and fieldbus types mapped to OSI layers.
- Safety and certification specialists using IEC 61784 functional safety and installation profiles alongside IEC 61158.
- Software developers implementing application layer services and service description models.
Practical uses include selecting appropriate fieldbus technology, aligning implementations with IEC profiles (IEC 61784), documenting application layer services, and ensuring consistent naming/addressing and data‑type definitions across devices.
