Overview
IEC 62769-2:2015, titled Field Device Integration (FDI) - Part 2: FDI Client, is an international standard published by the International Electrotechnical Commission (IEC). This standard specifies the architecture and detailed requirements for the FDI Client component within the broader FDI architecture. The FDI initiative aims to harmonize the integration of field devices with control and asset management systems, improving interoperability, simplifying device lifecycle management, and ensuring seamless communication and data exchange.
The standard defines the device access services, hosting services, User Interface Presentation (UIP) capabilities, actions, and User Interface Description (UID) necessary for an FDI Client to interact efficiently with field devices and FDI Servers.
Key Topics
-
Device Access Services
IEC 62769-2 outlines crucial device access services, including:
- Device and Node models for data representation
- Service definitions for property access and manipulation
- Locking mechanisms to coordinate device access
- Direct access provisions for enhanced control
- Data types specific to field device integration
-
Hosting Services
The standard covers hosting service functionalities that enable the FDI Client to manage and interact with hosted device integrations effectively. Parameter type definitions support consistent handling of device-related data.
-
User Interface Presentation (UIP)
UIP enables standardized presentation and interaction with device data on client systems:
- Services dedicated to UI rendering and dynamics
- Rules for UIP instantiation and life cycle management
- State machine definitions and permissions model
- Download mechanisms from FDI Servers for UIP components
-
Actions and User Interface Description (UID)
The FDI Client supports executing actions triggered by the user or system events:
- Action request and response schemas
- Sequence diagrams illustrating action handling flow
- UID specifications for consistent UI execution and rendering tailored to device functionalities
-
XML Schema Definitions
IEC 62769-2 includes an extensive set of XML schema definitions for data exchange and service invocation, ensuring interoperability and extensibility in device integration.
Applications
The IEC 62769-2:2015 standard is essential for industries relying on smart field devices within automation, instrumentation, and control frameworks. Applications include:
-
Process Automation
Streamlining device integration for process plants to enable real-time monitoring, diagnostics, and control.
-
Asset Management Systems
Enhancing asset life cycle management by ensuring device data is accessible and manageable via standardized clients.
-
Industrial IoT (IIoT)
Facilitating seamless connectivity of field devices to digital enterprise systems, improving analytics and predictive maintenance.
-
Device Configuration and Maintenance
Providing uniform client functionality to configure, operate, and maintain a wide variety of field devices regardless of vendor.
-
Control Systems Integration
Enabling controllers and host systems to incorporate diverse device types with reduced integration complexity and lower total cost of ownership.
