IEC TR 62453-51-90:2017

Overview

IEC TR 62453-51-90:2017 is a Technical Report from the International Electrotechnical Commission (IEC) that documents how HART® technology is integrated into the COM‑based implementation of the FDT (Field Device Tool) interface - the Common Object Model implementation (see IEC TR 62453‑41). Edition 1.0 (2017‑06) specifies the communication implementation and supporting services for the IEC 61784 CPF 9 profile (HART) based on IEC 62453‑309. This document provides informative guidance for developers and system integrators; it does not replace or modify the FDT specification itself.

Key topics and requirements

The report focuses on protocol-specific integration points and data models required to enable interoperable FDT/DTM solutions for HART devices. Key technical topics include:

• Communication schemas and data types for HART integration (e.g., FDTHARTCommunicationSchema).
• Channel parameter definitions for HART channels (FDTHARTChannelParameterSchema).
• Network management and addressing details, including HART device addressing and bus category mapping for IEC 61784 CPF 9.
• Device and instance data access requirements for DTM methods (IDtmParameter, IDtmSingleDeviceDataAccess, IDtmSingleInstanceDataAccess) to ensure access to parameters defined in IEC 62453‑309.
• Device identification and topology scan schemas, including FDTHARTIdentSchema, FDTHART_ExtendedIdentSchema, DTMHARTDeviceSchema, FDTHARTScanIdentSchema and related extended variants.
• XSLT transformation guidance for converting identification and device description data between formats.
• Conventions and normative references to ensure consistent implementation across vendors.

The document uses mandatory/recommended vocabulary (shall/should/can) to indicate requirement levels for FDT component behaviour inside a COM-based architecture.

Practical applications

• Enabling DTM (Device Type Manager) vendors to implement communication and device models for HART devices that work within COM‑based FDT hosts and engineering tools.
• Assisting system integrators and control system vendors to integrate HART field devices into heterogeneous process automation environments using FDT.
• Guiding engineering tool developers to support HART device scans, identification, channel parameters and data access in accordance with IEC 62453 series interoperability expectations.

Who should use this standard

• DTM and FDT component developers
• Field device manufacturers using HART
• Control system and engineering tool vendors
• System integrators in process industries seeking standardized HART integration
