PCM600 takes care of 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 the
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
• 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.
