Close the window ifit does not close automatically.4.6.1 IEC 61850 naming conventions to identify an IEDThis section is only valid when the IEC 61850 standard is used for station buscommunication. According to the IEC 61850–6 clause 8.4, the SCL model allowstwo kinds of project designation in the object properties.• A technical key is used on engineering drawings and for signal identifications.This is contained in the attribute name as identification of each object. If thisvalue is used as reference to an object, it is contained in an attribute namestarting with a string denoting the reference target object type, and ending withthe string Name. The technical key is used within SCL for referencing otherobjects. Observe that name is a relative identification within a hierarchy ofobjects.• A user oriented textual designation is contained in attribute desc. Attributes arenot allowed to contain carriage return, line feed or tab characters. Thesemantics of desc shall also be relative within an object hierarchy.PCM600 takes care of these two possibilities. The two possible signal designationsare available per object in the object properties for all hierarchical levels beginningwith the station as the highest level.The technical key is automatically generated based on the rules and typespecifications of IEC 61346 and the extended definitions done for substations by atechnical committee. The technical key is shown in the Object Properties underSCL Technical Key or Technical Key.• The station level is predefined by "AA1", where 1 is the index.• The voltage level is predefined by "J1", where 1 is the index.• The bay level is predefined by "Q01", where 01 is the index.• The IED is predefined by "A1", where 1 is the index.The predefined full path name of the technical key for the IED would beAA1J1Q01A1.For all practical engineering purposes (both towards the IED and towards the61850 engineering process), the user should keep the default SCL technical key. Itis however possible, due to for example company naming policies, to rename theSCL technical key for the station level, voltage level, bay level and IED level usingthe Object properties window as shown in Figure 16.Section 4 1MRK 511 261-UEN -Setting up a project34 650 seriesEngineering Manual
