The IED engineering tool must be able to receive an SCD file or an ICD file as an import to receive the engineered communication extensions, for example, for the different IEDs.
To be able to import an SCD file at station level, the option IED 61850 configuration engineering mode enabled has to be cleared in PCM600.
If the IED 61850 configuration engineering mode is enabled, SCD files cannot be imported and an error message is shown.
