Overview
IEC 62769-1:2015, titled Field Device Integration (FDI) - Part 1: Overview, is an international standard published by the International Electrotechnical Commission (IEC). This standard provides a comprehensive introduction and conceptual framework for the Field Device Integration (FDI) technology. It explains the motivation, architecture, and deployment concepts that support the seamless integration of field devices into automation and control systems.
FDI aims to unify and simplify the interaction with field instrumentation by combining established technologies like Electronic Device Description Language (EDDL), Field Device Tool (FDT), and OPC Unified Architecture (OPC UA). IEC 62769-1 serves as the foundation for the entire multi-part FDI standard series and guides users in understanding the scope and practical applications of the FDI specifications.
Key Topics
-
FDI Concepts and Motivation
The standard explains the need for a unified integration approach to address challenges in configuring, operating, and maintaining field devices from diverse vendors.
-
Core Technologies
- Electronic Device Description Language (EDDL): Enables standardized device descriptions for configuration and diagnostics.
- Field Device Tool (FDT): Provides a generic framework for device integration using device-specific plug-ins.
- OPC Unified Architecture (OPC UA): Delivers secure, platform-independent communication and information modeling.
-
FDI Architecture
- Integration of FDI Packages which encapsulate device-specific information and user interfaces.
- Definition of FDI Clients, Servers, and Communication Servers for deployment flexibility.
- Support for user interface tiering to optimize device management workflows.
-
Security and Redundancy
Guidance on safeguarding data exchange and ensuring system reliability through redundancy features.
-
Life-cycle Model
Covers versioning, identification mechanisms, and forward compatibility ensuring seamless evolution and update management for FDI components.
Applications
IEC 62769-1:2015 is essential for professionals involved in:
-
Industrial Automation
Facilitating interoperability among field devices from multiple manufacturers within process control, manufacturing, and enterprise systems.
-
Device Configuration and Management
Allowing engineering, operator, and maintenance stations to effectively interact with intelligent field devices using standardized interfaces.
-
Integration of Device Tools
Supporting the deployment of third-party, handheld, and generic OPC UA-based device management tools.
-
System Security and Reliability
Enabling implementers to design secure, robust communication between devices and management systems while maintaining system uptime through redundancy.
This overview standard educates system architects, engineers, and software developers on the practical benefits of adopting FDI technology - simplifying device integration, reducing engineering efforts, and promoting vendor-neutral solutions.
