Figure 122: SCL Import Options
• Don't import protects the existing IEDs if the SCD file does not match the
original configuration in PCM600.
• Replace unknown can be used when the file includes additional IEDs that
are needed. The IED of type "Generic IEC 61850 IED" is used to integrate
this kind of IEDs into, for example, the plant structure.
• Ignore PCM Object Type updates the IED objects in PCM600 from the
IED types in the SCD file, whether or not the IED types in the SCD file
match the IED objects in PM600.
• Ignore Substation Section does not import the SSD file part of the SCD
file.

Writing communication configuration to IED

IEC 61850 communication depends on the proper communication configuration in all
IEDs that communicate via IEC 61850.
It is possible to make a configuration change in one IED, without affecting the
horizontal communication (GOOSE or IEC 61850-9-2 LE) engineering between
IEDs. For example, when the Application Configuration tool configuration is
changed, but no changes are done to the instantiation or deletion of functions that
represent a logical node.
When a changed configuration is written to the IED, the horizontal communication
configuration needs to be updated.
