Overview
IEC 62769-4:2021 - Field Device Integration (FDI) Part 4: FDI Packages defines the model, contents and lifecycle rules for FDI Packages used to deliver device descriptions, communication profiles and user interface plug‑ins for automation devices. The standard specifies which architectural components of the overall FDI architecture are in scope and how packages are structured, versioned, signed and deployed to FDI Hosts.
Key topics and technical requirements
- FDI Package Model: Defines package elements such as the Package Catalog, Electronic Device Description (EDD), User Interface Plug‑in (UIP) and attachments (images, protocol files, documentation).
- Package Types: Differentiates Device Packages, Communication Packages, UIP Packages and Profile Packages for flexible delivery of device and protocol support.
- Packaging technology & Open Packaging Conventions (OPC): Recommends packaging approaches and handling of unknown/invalid parts, relationships, thumbnails and core properties.
- Package parts & schema: Normative XML schema elements and content types (catalog entries, device types, communication profiles, localized strings, etc.) are specified for interoperability.
- Versioning and compatibility: Version scheme, version hierarchy and UIP compatibility rules ensure safe updates and backward compatibility between device descriptions and host software.
- Security & provenance: Requirements for digital signatures, registration certificates and signing mechanisms to verify package origin and integrity.
- Lifecycle and deployment: Use cases and policies for creation, installation, update, upgrade, replacement and uninstallation of FDI Packages; file name conventions and handling recommendations are included.
- Special topics: Normative annexes cover health status methods, modular device handling, communication‑server packages and protocol‑specific profiles.
Practical applications and who uses it
- Device manufacturers: package and distribute EDDs, UIPs and protocol support for field devices (sensors, actuators, transmitters).
- System integrators and control system vendors: integrate validated FDI Packages into FDI Hosts (asset management systems, control platforms) for standardized device commissioning, diagnostics and configuration.
- Software developers: build FDI Host implementations that parse catalogs, enforce versioning, validate digital signatures and present UIPs.
- Plant engineers and maintenance teams: benefit indirectly through reliable device integration, consistent device lifecycle management and secure package provenance.
