Overview - IEC TR 61804-6:2012 (EDDL integration guidance)
IEC TR 61804-6:2012 is a Technical Report that evaluates and assesses the Electronic Device Description Language (EDDL) technology for integrating fieldbus devices into engineering tools. It explains how EDDL (and EDD files) can meet user requirements such as those in the NAMUR NE 105 recommendation and provides guidance for device manufacturers, system integrators and end‑user practitioners. The report focuses on investment protection, long‑term viability, ease of device management and minimizing the need to install third‑party software on core systems (DCS servers, operator consoles).
Key topics and technical requirements
The TR analyzes EDDL capability against a set of practical requirements and contains sections that cover:
- Requirement analysis mapped to NAMUR NE 105 topics (investment safety, version conflicts, certification, etc.)
- Integration of devices (installation, removal, and configuration in engineering tools)
- User guidance and display (consistent, intuitive presentation of device data)
- Standard profiles and device descriptions (content, structure and completeness of EDD files)
- Licensing and cross‑platform compatibility (deployment and reuse of EDD files)
- Full support of device functionality and standardized data filing for device management and diagnostics
- Certification and audit trail expectations for device descriptions and tools
Technical building blocks discussed include the EDDL interpreter, development toolkits, compressed text EDD files (not executable software), and interoperability concepts such as backwards/forward compatibility.
Practical applications and target users
Who should use this standard and how:
- Device manufacturers: to create compliant EDD files that enable seamless integration with DCS and asset management tools.
- Control system and DCS vendors: to support EDDL in engineering and operator software without adding proprietary drivers.
- System integrators and engineering tool developers: to implement interpreters, tokenizers and toolchains that handle EDD content and meet NAMUR NE 105 expectations.
- Maintenance, instrumentation and plant asset management teams: to leverage standardized device descriptions for configuration, calibration, diagnostics and audit trails.
Typical use cases include handheld field communicators, DCS engineering stations, operator displays, device management modules in plant asset management solutions, and standalone laptop/tablet tools.
