Overview
IEC TR 62453-51-32:2017 is a Technical Report by the IEC that explains how to integrate PROFINET® technology into the COM-based implementation of the Field Device Tool (FDT) interface using the Common Object Model. It specifies the communication implementation and related services for IEC 61784 CP 3/4, CP 3/5 and CP 3/6 devices based on IEC 62453‑303‑2. This document provides implementation guidance (schemas, data types and method usage) for DTM and FDT component developers-it does not contain nor modify the FDT specification itself.
Key technical topics and requirements
- Scope and mapping: Defines how PROFINET (PNIO) concepts map into the COM-based FDT common object model; aligns with IEC 62453-303-2 and IEC TR 62453-41.
- Communication and service schemas: Provides XML/schema artifacts referenced by implementers, including:
- FDTProfinetIOParameterSchema
- FDTProfinetIOCommunicationSchema
- FDTProfinetIOChannelParameterSchema
- Identification and scan schemas (e.g., FDTProfinetIOIdentSchema, DTMProfinetIODeviceSchema, FDTProfinetIOScanIdentSchema, FDTProfinetIODeviceIdentSchema)
- XSLT transformation guidance for data conversion
- Data types and protocol usage: Specifies protocol-specific use of general FDT datatypes (e.g., fdt:address, fdt:protocolId, fdt:deviceTypeId, manufacturer and semantic IDs).
- Network management and addressing: Describes PNIO device address handling (stored under ) and network management data types used by parameter access methods.
- Required method support: Indicates which COM/FDT methods should provide access to the defined parameters, for example:
- IDtmParameter:GetParameters / SetParameters
- IDtmSingleDeviceDataAccess, IDtmSingleInstanceDataAccess
- Conformance note: Uses the IEC vocabulary for requirement levels (“shall”, “should”, “can”). The report corrects and updates mappings from earlier editions.
Practical applications and who uses it
- Device manufacturers and DTM developers: implement PROFINET communication services inside DTMs to ensure consistent behavior with FDT hosts.
- FDT host/frame vendors and system integrators: enable consistent discovery, parameter access, and engineering workflows for PROFINET devices within heterogeneous automation systems.
- Automation and instrument engineers in the process industry: benefit from interoperable device integration in engineering tools and reduced integration effort.
- Useful for projects requiring PROFINET – FDT interoperability, device topology scans, PNIO addressing, and standardized parameter exchange.
