PCM600 takes care of these two possibilities. The two possible signal designations are
available per object in the Object Properties for all the 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, a short form should be used,
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, the 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.
