value is used as reference to an object, it is contained in an attribute name
starting with a string denoting the reference target object type, and ending with
the string Name. The technical key is used within SCL for referencing other
objects. Observe that name is a relative identification within a hierarchy of
objects.
• A user oriented textual designation is contained in attribute desc. Attributes are
not allowed to contain carriage return, line feed or tab characters. The
semantics of desc shall also be relative within an object hierarchy.
PCM600 takes care for these two possibilities. The two possible signal
designations are available per object in the object properties for all hierarchical
levels beginning with the station as highest level.
The technical key is automatically generated based on the rules and type
specifications of IEC 61346 and the extended definitions done for substations by a
technical committee. The technical key is shown in the Object Properties under
SCL 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 be
AA1J1Q01A1.
For all practical engineering purposes (both towards the IED and towards the
61850 engineering process), the user should keep the default SCL technical key. It
is however possible, due to for example company naming policies, to rename the
SCL technical key for the station level, voltage level, bay level and IED level using
the Object properties window as shown in
• The station level has been renamed as "DMSTAT"
• The voltage level has been renamed as "C1"
• The bay level has been renamed as "Q1"
• The IED has been renamed as "SB1"
The renamed full path name of the technical key for the IED would be
DMSTATC1Q1SB1.
