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
