Introduction

FDI is a standard device integration technology. One of its core elements is the Electronic Device Description Language (EDDL) which is used to completely specify a (field) device with its parameters and behaviour. The FDI Information Model (IEC62769-5) specifies how each individual device together with the communication topology is exposed using OPC UA. The Information Model is driven largely by the Device Definitions and is based on OPC UA for Devices (DI). A secondary OPC UA model has been specified for the so-called FDI Communication Servers (IEC62769-7). Each FDI Communication Server represents a specific Fieldbus Protocol. The OPC UA Interface makes the protocol-specifics transparent to the FDI Server.

FDI Capabilities

FDI Host

URN:          https://opcfoundation.org/wiki/index.php/Field_Device_Integration_(FDI)#FDI_Host

Discovery ID: FDI


Description
Understand and support the OPC UA for FDI Information Model (IEC62769-5).

Usage Considerations
Support third-party Tools that contain an FDI Client and communicate with the automation system’s FDI Server. Third-party tools may also be applications running on handheld devices.
Allow interoperation with OPC UA Clients that are not FDI-aware. Examples are HMI Clients, MES or ERP Clients.

Conformance Testing

Client Server
  • Interpret and execute FDI user interface descriptions (UID)
  • Load, host, and run FDI user interface Plug-Ins (UIP)
  • Expose the information of an FDI package following the FDI information model
  • Allow access to elements of the device via the FDI information model

FDI Communication Server

URN:          https://opcfoundation.org/wiki/index.php/Field_Device_Integration_(FDI)#FDI_Communication_Server

Discovery ID: FDIC


Description
Understand and support the OPC UA for FDI Information Model for Communication Server (IEC62769-7).

Usage Considerations
Integrate devices with protocols that are not natively known to the FDI Host.

Conformance Testing

Client Server

Client (FDI Host / Server) is able to use FDI Communication Server

Support the FDI Communication Server information model to represent a specific device protocol
