3.3 Conventions
For the purposes of this document, the conventions given in IEC 62769-1 apply.
4 FDI Package Model
4.1 Overview
The FDI Package Model (see Figure 2) provides all the elements necessary to integrate devices, network components and FDI Communication Servers into a system.
Figure 3 shows the mapping of the FDI Package functional elements, as specified in IEC 62769-1 , to the physical elements in an actual FDI Package, as specified in this document.
The Electronic Device Description (EDD) corresponds to the Device Definition, the User Interface Description, and the Business Logic functional elements. A set of physical User Interface Plug-ins corresponds to the User Interface Plug-in functional element.
The other physical elements in the FDI Package, the Package Catalog and Attachments, provide support for basic mechanisms such as identification, versioning and deployment, and distribution of manufacturer and/or protocol-specific information about the device and/or the User Interface Plug-ins.
4.2FDl Package Elements4.2.1 Package Catalog
The Package Catalog is a required element that provides information about the contents ofthe FDI Package including, but not limited to，identification and version information,devicetype information，hardware and input/output device requirements，FDl Technology Version,and protocol-specific characteristics.
The Package Catalog is used by an FDI Server to create a catalog of device types and tocreate DeviceType Nodes in the information Model.
4.2.2Electronic Device Description
The EDD is an element that provides Device Definition，User Interface Descriptions,andBusiness Logic to an FDI Server.
Subclause 4.3 specifies for which FDl Package types an EDD is required.
To maximize interoperability, the initial setup of a device shall be achievable solely with theUser Interface Descriptions, Device Definition and Business Logic that are part of the EDD inthe FDl Device Package. The use of User Interface Plug-ins is optional and targeted inparticular for the complete setup of complex devices.
4.2.3User Interface Plug-in
A User Interface Plug-in (UIP) is an element that enables an FDI Client to present aprogrammed user interface.The FDI Server only stores the UlP from a consumed package; itdoes not execute or interpret the UIP.
A UIP is referenced from a User Interface Description. Those references are reflected in theInformation Model through functional groups (see lEC 62769-5).References to UIPs in theInformation Model are logical through a unique reference.The physical structure of the UlP isnot at the Information Model level.Physically, a single uIP may consist of one or more uIPVariants, each targeted at a specific platform and run-time environment.
Figure 4 illustrates the logical reference to a UlP in the EDD and the physical structure of thatuiP.The EDD of the FDl Package references a globally unique identifier of the UIP. Inaddition, the Package Catalog also lists the UlPs required by the device type along with theversions of the UIP supported by the package.
A UIP can be designed to meet different platform requirements since not all platforms support the same screen sizes and input devices. When an FDI Client requests a UIP specifying the platform type, the deployment mechanism in the FDI Server looks for a UIP Variant that meets the platform type specified and returns it to the FDI Client. The target platform defines specific screen resolutions and input devices that shall be supported by the UIP Variant. Available target platforms are described in Table 1 .IEC 62769-4 pdf download.
