Engineering concept in IEC 61850-6
•
Top-down approach means that the system engineering tool has ICD files available
for each IED to be included in the system configuration. The ICD files may be of the
template type and represent a pre-configured IED.
•
Bottom-up approach means that the configurations are produced by the IED tool, and
that are exported as CID files (or SCD file) to be imported into the system tools.

Relation between system and IED tools
Regardless of the engineering approach, the idea is that the IED tool provides the CID or
ICD file for each IED. These ICD/CID files are then imported into the system tool and
merged into a SCD file, representing the complete substation or a part of the substation,
like one for each voltage level.
