ISO 15745-3:2003

Overview

ISO 15745-3:2003 - part of the ISO 15745 family - defines technology-specific elements and rules for describing device and communication network profiles for IEC 61158-based control systems. Used together with ISO 15745-1:2003 (generic reference), this part provides profile templates and syntax to represent communication-related aspects of resource profiles for fieldbus technologies such as ControlNet, PROFIBUS, P‑NET, WorldFIP, and INTERBUS. The standard focuses on profile templates (XML/GSD/EDS encodings), header and syntax rules, and mapping into the broader Application Integration Framework (AIF).

Key topics and technical requirements

• Technology-specific profile templates: Device profile and communication network profile templates for IEC 61158-based systems, with rules for content and syntax.
• Profile file formats and encodings: XML schemas and encapsulation approaches; support for Electronic Data Sheets (EDS) and Generic Station Description (GSD) where applicable.
• Device and network profile elements: Definitions for device identity, device manager objects, network parameters and transport/application layer descriptions as required by each fieldbus technology.
• Integration model alignment: Rules to include device/network profile instances in resource profiles using the ProfileHandle_DataType defined in ISO 15745-1.
• Normative annexes: Detailed templates and schemas per technology (e.g., ControlNet EDS requirements, PROFIBUS GSD semantics, INTERBUS device templates).
• Scope boundaries: Excludes ISO/IEC 8802-3 (Ethernet) based control systems - covered by other parts of ISO 15745.

Applications and who uses it

Practical uses of ISO 15745-3:2003:

• Enabling systematic application interoperability profiles (AIPs) and resource selection for industrial automation projects.
• Creating vendor and device-neutral device profiles and communication network profiles for design, configuration, and documentation.
