IEC TR 62453-51-31:2017

Overview

IEC TR 62453-51-31:2017 is a Technical Report from the IEC that provides guidance for integrating the PROFIBUS protocol into the COM-based implementation of the Field Device Tool (FDT) interface (the Common Object Model described in IEC TR 62453‑41). It specifies the communication implementation for IEC 61784 profiles CP 3/1 and CP 3/2, mapping PROFIBUS protocol behaviour and services into the FDT COM object model. This document complements-rather than replaces-the FDT specification and is intended for developers implementing FDT components that must interoperate across heterogeneous automation systems.

Key Topics and Technical Requirements

• Scope and relationship: Aligns with IEC 62453-303-1 and the IEC 62453 series; focuses on COM-based FDT integration for PROFIBUS CP 3/1 and CP 3/2.
• DTM models: Guidance for different Device Type Manager (DTM) architectures including monolithic DTMs, composite device DTMs, gateway DTMs, and modular gateway DTMs.
• Bus master configuration (BMCP): Interfaces and information related to bus master configuration and handling of configuration changes and error cases (for example, when a DTM refuses a new BMCP).
• Protocol-specific behaviour: Rules for representing device modularity, configuration change handling, and expected error behaviour for PROFIBUS devices within the FDT object model.
• Data types and schemas: Definitions and usage for network management, communication data types (including DPV0 and DPV1 communication schemas), channel parameters, and device identification schemas.
• Topology and scanning: Data structures for topology scan results, scan identification, and device type identification; includes guidance on XSLT transformations and example DTM documents.
• Normative references: Relies on standards such as IEC 61158, IEC 61784-1, IEC 62453-1/-2, IEC TR 62453-41, and IEC 62453-303-1.

Practical Applications and Who Uses It

This TR is practical for:

• DTM developers and software vendors implementing FDT COM components for PROFIBUS devices.
• Device manufacturers creating device-specific DTMs to ensure consistent integration with engineering tools.
• Control system integrators and engineering tool vendors that must support heterogeneous fieldbuses and PROFIBUS networks within FDT-enabled environments.
• Automation engineers who need reliable mappings of PROFIBUS communication and network management into higher-level engineering tools.

Benefits include improved interoperability, standardized device representation, and clearer rules for bus configuration and error handling when integrating PROFIBUS into FDT-based toolchains.
