7.3.3.2 Importing ICD or CID files1. Select an existing IED to import IEC 61850 files.2. From the Files of type list, select the file type of IEC 61850 to be imported (ICDor CID).The SCL Import Option dialog box opens.3. In the SCL Import Option dialog box, select how the file is to be handled duringthe import.IEC09000631-1-en.vsdIEC09000631 V1 ENFigure 69: IEC 61850: SCL import options• Don't import protects the existing IEDs in case the SCD file does notmatch the original configuration in PCM600.• Replace unknown can be used when it is known that the file includesadditional IEDs that are needed. The IED of type “Generic IEC 61850 IED”is used to integrate these kinds of IEDs into, for example, the plant structure.• Ignore PCM Object Type updates the IED object(s) in PCM600 from theIED type(s) in the SCD file, discarding whether or not the IED type(s) inthe SCD file matches the IED object(s) in PM600.• Ignore Substation Section does not import the SSD file part of the SCD file.4. Click Import when the definition has been completed.A progress view displays the importing procedure.7.3.4 Writing communication configuration to the IEDIEC 61850 communication depends on the proper communication configuration in allIEDs that communicate via IEC 61850.It is possible to make a configuration change in one IED, without affecting thecommunication engineering.
