IEC 62769-7-2021 Field device integration (FDI) – Part 7: Communication devices.
5 FDI Communication Package
5.1 General The FDI Server imports the FDI Communication Package like any other FDI Device Package. Clause 5 specifies the FDI Communication Package details. 5.2 EDD 5.2.1 General rules The FDI Communication Package contained EDD is not restricted, but bound to a protocol- specific annex (IEC 62769-4:2020, Annex F). The EDD elements as specified in IEC 62769-4:2020, Annex F, and provided with an FDI Communication Package shall describe:
a) Parameter and parameter structures. Mandatory protocol-specific parameter definitions are found in IEC 62769-4:2020, Annex F. The parameters shall contain any parameter that requires adjustment for proper communication service operation.
b) Physical Layer identification. Protocol-specific definitions are found in IEC 62769-4:2020, Annex F. Communication devices’ modularity: The modularity information shall be based on using the EDDL constructs COMPONENT (see IEC 61 804-3). FDI envisions communication device modularity to cope with communication hardware providing multiple physical or logical communication channels to access multiple logical or physical communication networks. Each module element of the whole communication device shall be described by a separate EDD element.
c) The COMPONENT definition shall be used to support the system implemented topology configuration. Protocol-specific definitions are found in IEC 62769-4:2020, Annex F. The related COMPONENT definitions are described in 5.2.2, 5.2.3, 5.2.4, and 5.2.7. d) The Business Logic shall contain a method enabled to validate the network (see 5.2.8). The validation function considers the elements only directly connected to the network. The validation function shall be referred by the EDDL specified CHECK_CONFIGURATION attribute.
e) The Business Logic can contain a method enabled to validate the module configuration (see 5.2.9) or the network configuration (see 5.2.8). The validation function considers the elements only directly connected to the related parent element in the topology. The validation function shall be referred by the EDDL specified CHECK_CONFIGURATION attribute.
f) Connection Point data: The Connection Point (see 5.2.4 and 5.2.6) shall be described through EDDL constructs COMPONENT, COLLECTION and VARIABLE. The COMPONENT definition associates the Connection Point element to the Communication Device. The VARIABLE definitions represent the properties of a specific Connection Point.
The COLLECTION represents the Connection Point structure as such. Protocol-specific definitions are found in IEC 62769-4:2020 Annex F.
The Menu structure shall follow the Menu conventions for PC-based applications in accordance with IEC 61 804-4, which enables access to:
1 ) FDI Communication Device Type (Bus) parameters: These parameters shall be made accessible by means of “offline_root_menu”.
2) Topology Configuration Dialogs shall be made available by means of the menu entry point “topology_configuration”.
