Overview
IEC 62769-1:2021 is the Part 1 overview of the Field Device Integration (FDI) international standard. It describes the concepts, motivation and high-level architecture of the FDI specifications and explains the intent and structure of the multi-part IEC 62769 series. Reading this document helps stakeholders understand how FDI enables consistent field device integration, lifecycle management and interoperability across multiple device protocols and vendor tools.
Key topics
- FDI architecture and components: conceptual roles such as FDI Client, FDI Server, FDI Communication Server, and FDI Packages.
- FDI Packages: distribution mechanism for device-specific resources and tools.
- Information and technology mapping: references to the FDI Information Model and Technology Mapping parts that define how device data is modeled and exposed.
- Protocol extensibility: support for a generic protocol extension to accelerate adoption of new or different communication technologies.
- Security and integrity: digital signatures for FDI Packages and trusted timestamping to support long-term validation.
- Deployment and lifecycle: guidelines for deployment (engineering, operator and maintenance stations, handhelds), versioning, identification mechanisms, forward compatibility and lifecycle management.
- Terminology and references: alignment with OPC UA (IEC 62541 series), EDDL and FDT concepts and common definitions.
- Redundancy and security considerations for resilient and secure operation.
(These topics are described at a conceptual level in Part 1; technical details are in subsequent parts of IEC 62769.)
Applications and users
IEC 62769-1 is intended for professionals involved in industrial automation and device integration, including:
- Control system architects and system integrators planning device interoperability strategies.
- Device vendors packaging device integration assets (device packages, digital signatures).
- Automation software developers building FDI Clients, Servers or Communication Servers or integrating OPC UA clients.
- Maintenance and asset engineers implementing lifecycle and versioning strategies for field instrumentation.
- Certification bodies and IT/security teams assessing package integrity and trusted timestamping.
Practical use cases include multi-vendor device integration, centralized device management, secure deployment of device tools, and enabling protocol-agnostic device access.
