Overview
IEC 62453-1:2009 - Field Device Tool (FDT) interface specification, Part 1: Overview and guidance - is the introductory part of the IEC 62453 series. It presents an overview of the FDT approach for integrating field devices and engineering tools in industrial automation. This part explains the structure and content of the series, clarifies concepts common to many parts, and describes relationships to related standards. IEC 62453-1 frames the FDT model used to enable vendor-supplied device components to interoperate with system-level engineering and lifecycle tools.
Key topics and technical requirements
- FDT conceptual model: explanation of the FDT architecture including Frame Applications, Device Type Manager (DTM), communication channel concept and presentation objects.
- Client/server interface: guidance on the common application interface that supports function control and data access in a client/server architecture (enabling interoperability between engineering tools and device DTMs).
- Device Type Manager (DTM): manufacturer-supplied software component model tied to specific field devices or modules; how DTMs integrate into engineering tools.
- Communication profile integration: references to parts that integrate FDT with specific fieldbus/profiles (see Parts 3xy and 5xy in the series).
- Object model and styleguides: provisions for object model integration profiles (Parts 4x) and DTM styleguides (Parts 6x) to ensure consistent DTM implementations.
- Guidance and implementation material: migration guidance to DTM, UML notation annex, implementation policy and a bibliography for further study.
- Interoperability focus: emphasis on open interfaces to support multiple manufacturers, heterogeneous fieldbuses and plant-wide tool integration.
Practical applications and users
Who uses IEC 62453-1 and the wider FDT framework:
- Device and module manufacturers: develop DTMs to expose device configuration, diagnostics and parameter access.
- System integrators and OEMs: integrate heterogeneous devices into a common engineering environment.
- Tool vendors: build Frame Applications and engineering tools that host DTMs and use the FDT client/server interfaces.
- Plant operators and lifecycle managers: gain unified access for configuration, commissioning, maintenance and asset management across different fieldbusses.
Benefits include simplified device integration, reduced engineering and maintenance costs, improved plant lifecycle management, and vendor-neutral interoperability.
