Field Device Integration (FDI)
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.
Understand and support the OPC UA for FDI Information Model (IEC62769-5).
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.
FDI Communication Server
Understand and support the OPC UA for FDI Information Model for Communication Server (IEC62769-7).
Integrate devices with protocols that are not natively known to the FDI Host.
Client (FDI Host / Server) is able to use FDI Communication Server
Support the FDI Communication Server information model to represent a specific device protocol
