Overview
IEC TS 62453-43:2024 - Field device tool (FDT) interface specification, Part 43: Object model integration profile – CLI and HTML - specifies how FDT principles are implemented using CLI technology and web technologies for graphical user interfaces. It defines object behaviour and object interaction via .NET Standard interfaces and JavaScript APIs, and is specified for FDT version 3.0. Emphasis is placed on support for distributed Frame Application (FA) architectures, enabling modern, multi-platform device integration and web-based DTMs (Device Type Managers).
Key topics and technical requirements
The specification covers a broad set of technical topics and implementation rules, including:
- Implementation concept: mapping of the abstract FDT object model to concrete CLI and HTML implementations, and rules for Frame Applications (FA) and DTMs.
- Object interaction and behaviour: .NET Standard interfaces, JavaScript APIs, synchronous/asynchronous methods, events, exception handling and datatype rules.
- User interfaces: support for HTML versions, JavaScript versions, and Web UI patterns for DTM presentation and user interaction.
- Distributed FA architectures: system communication, data exchange between FAs, nested and point-to-point communication, and dynamic network changes.
- DTM business logic and categories: device DTMs, communication DTMs, gateway DTMs, composite and module DTMs, and related function access control.
- Data persistence & synchronization: DTMDataSet structures, persistence types and rules for synchronizing device and DTM data.
- Topology, addressing & scanning: topology management, address management, scanning and DTM assignment.
- Concurrency & threading: threading rules, deadlock avoidance, locks and race conditions for reliable multi-threaded implementations.
- Localization & user management: culture handling, UI language switching, multi-user access and user levels.
- Lifecycle, audit trail & identification: DTM instance identification, lifecycle concepts, and audit event definitions.
Practical applications
IEC TS 62453-43:2024 is intended for:
- Developers building DTMs and Frame Applications using .NET and web technologies (JavaScript/HTML).
- System integrators and control system vendors implementing multi-vendor device integration, distributed FDT architectures, and web-based engineering tools.
- Automation engineers who require standardized device configuration, diagnostics, and lifecycle management across fieldbus and industrial networks.
- Tooling vendors creating PLC/SCADA interfaces or asset management solutions that consume FDT-compliant objects and web UIs.
Related standards
- This Technical Specification is part of the IEC 62453 (FDT) family of standards. Implementers should consult other parts of the IEC 62453 series for interoperability, packaging and additional profiles.
