IEC 62769-109-1:2020

Overview

IEC 62769-109-1:2020 is the IEC Field Device Integration (FDI) profile for HART® (IEC 61784‑1 CP 9/1) and WirelessHART® (IEC 61784‑1 CP 9/2). Edition 2.0 (2020) is a technical revision that cancels and replaces the 2015 edition. The standard defines how HART and WirelessHART devices are represented, discovered and managed within FDI packages and tools, enabling consistent device integration, configuration and diagnostics across control and asset-management systems.

Key Topics and Technical Requirements

• FDI profile for HART / WirelessHART: Standardizes the catalog, communication profile and device profile representations for CP 9/1 and CP 9/2 devices.
• Information model mapping: Defines ProtocolType, DeviceType and FunctionalGroup mappings so tools can interpret device functionality consistently.
• Topology elements: Specifies ConnectionPoint types (TP, IP, TDMA), Communication Device, Communication Service Provider and Network representations used for device discovery and addressing.
• Methods and services: Includes method definitions for Communication Servers and Gateways such as Connect, Disconnect, Transfer, GetPublishedData and SetAddress - enabling standardized runtime interactions.
• Annexes for implementers:
  • Topology scan schema (Annex A) for structured device/network discovery.
  • Transfer service parameters (Annex B) for data exchange semantics.
• Practical developer support: Adds support for a generic protocol extension to speed adoption of new technologies and enables Package Developers to create EDD-targeted packages under a unified toolchain.
• Edition and IP notes: The document is a redline Edition 2.0 (2020) and includes patent declarations for certain methods; implementers should review licensing statements in the standard.

Applications and Who Uses It

• Device manufacturers: Create FDI packages and EDDs that expose HART/WirelessHART device parameters and diagnostics to host systems.
• System integrators & control engineers: Integrate smart field devices into DCS/SCADA and asset-management systems with standardized discovery and configuration workflows.
• Software/tool vendors: Build FDI-compliant engineering tools, EDD authoring environments, communication servers and gateways that support HART/WirelessHART profiles.
• Plant owners & asset managers: Streamline device lifecycle management, commissioning and diagnostics across heterogeneous field networks.
