User-oriented textual designation is contained in the desc attribute. Attributes are not
allowed to contain carriage return, line feed or tab characters. The semantics of desc
must also be relative within an object hierarchy.
PCM600 takes care of the two possibilities. The two possible signal designations are
available per object in the object properties for all hierarchical levels beginning with
the station as the highest level.
The technical key is automatically generated based on the rules and type specifications
of IEC 61346 and the extended definitions assigned for substations by a technical
committee. The technical key is shown in the Object Properties dialog box under
SCL Technical Key or Technical Key.
The station is predefined by "AA1" where 1 is the index. To get the real station
name that is used, it is possible to rename the SCL Technical Key for the station
as the name used by the project. To minimize the word length, take a short form
because this name is used also in the transmitted messages to identify the events,
for example.
The voltage level. In the example it is 20 kV and J1 is selected from the list below
SCL Technical Key in the Object Properties dialog box.
The bay and the IED are appended with the coding defined in the IEC 61346
standard and the substation definition lists. In the example, Bay SCL Technical
Key part is Q01 and IED is A1.
The user-oriented textual designation is visible in the Plant structure view for each
object. It is the name given by default or changed by using the Rename function.
