Overview
IEC 62769-103-1:2020 is the International Electrotechnical Commission (IEC) profile specification for Field Device Integration (FDI) targeted at PROFIBUS networks. It defines an FDI profile that maps IEC 61784 communication profiles CP 3/1 (PROFIBUS DP) and CP 3/2 (PROFIBUS PA) into the FDI framework. This second edition (2020) replaces the 2015 edition and introduces technical revisions to accelerate technology adoption and streamline device package development.
Keywords: IEC 62769-103-1, FDI, PROFIBUS, PROFIBUS DP, PROFIBUS PA, IEC 61784, EDD, device package.
Key Topics and Technical Requirements
- Profile scope and purpose: Specifies how PROFIBUS devices and communication profiles are represented within the FDI information model to enable standardized device integration.
- Protocol support files & CommunicationProfile: Defines the structure for ProtocolSupportFile entries and CommunicationProfile definitions that describe supported protocols for device and communication packages.
- Device and protocol mapping: Rules for associating FDI Packages with devices (device type identification, revision mapping) and mapping EDDL/XML device descriptions to the FDI information model.
- Topology elements: Definitions for connection points, communication devices, service providers and network types (PROFIBUS DP and PA) used for topology discovery and device addressing.
- Methods and services: Standardized methods for FDI Communication Servers and Gateways (e.g., Connect, Disconnect, Transfer, SetAddress) and their arguments to control communication sessions.
- Transfer service parameters and schemas: Annexes provide normative schemas for topology scan results and transfer-service parameter definitions to ensure consistent data exchange.
- Developer support features: This edition adds support for generic protocol extensions and enables Package Developers to create EDDs (Electronic Device Descriptions) with a single development tool targeting current EDD-based systems.
- Standards compliance & patent notes: The document references normative IEC/PROFIBUS standards and contains patent declarations relevant to implementation.
Practical Applications and Users
Who uses IEC 62769-103-1:
- Device manufacturers creating PROFIBUS DP/PA devices and associated FDI device packages.
- Package Developers building EDDs and FDI Packages for integration tools.
- System integrators and automation engineers implementing PROFIBUS networks and FDI-based configuration/asset management.
- Software vendors of asset management, engineering, and control systems requiring standardized device integration.
Benefits:
- Improved interoperability between PROFIBUS field devices and FDI-enabled host systems.
- Faster adoption of new protocol variants via generic protocol extension support.
- Streamlined EDD/package development workflow for consistent device representation.
Related Standards
- IEC 62769 series (Field Device Integration)
- IEC 61784 (PROFIBUS communication profiles)
- EDDL / EDD and XML device description technologies
For device vendors and integrators working with PROFIBUS and FDI, IEC 62769-103-1:2020 is essential to ensure standardized, interoperable device integration and streamlined packaging of device descriptions.
