4.2.1 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，FDI 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.
4.2.2 Electronic 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 FDI 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 FDI Device Package. The use of User Interface Plug-ins is optional and targeted inparticular for the complete setup of complex devices.
4.2.3 User Interface Plug-in
A User Interface Plug-in (UIP) is an element that enables an FDl 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 UP isnot at the Information Model level.Physically, a single UlP 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 UIP 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 UIPs required by the device type along with theversions of the UIP supported by the package.
4.3.2 FDI Communication Package
The FDI Communication Package is intended to provide information about a single FDICommunication Device.The group of FDI Communication Devices splits into two sub-groups.FDI Communication Packages for Gateways
– Contain everything required to describe alldevice functions and logic required to bridge between different communication protocolnetworks, including the bridging algorithms (details are described in lEC 62769-7).
– FDI Communication Packages for FDI Communication Servers – Contain basic informationto describe the communication device and to integrate it into the FDl Host but also tocreate a valid reference to the external FDI Communication Server application. Thisapplication shall not be delivered as part of the FDI Communication Package.The FDICommunication Server provides access to single field devices or field device networks(details are described in lEC 62769-7).
Requirements to the FDI Communication Package content that are specific for FDICommunication Servers are defined in Annex J.
However，representatives of both groups are integrated into FDl Hosts by using FDICommunication Packages.Their physical structure is shown in Figure 7. Binary componentsnecessary to communicate to the communication hardware shall be provided outside thescope of this FDI Communication Package.
4.3.3 FDI UIP Package
The FDI UIP Package delivers User Interface Plug-ins to an FDl Server. It is used to distributeone or more UIPs that are intended to be shared by several device types. lts physicalstructure is illustrated in Figure 8.
