The parameter export and import function can be used, for example, when the protection relay's parameters are set using the WHMI instead of PCM600. The protection relay's settings engineered with PCM600 can be exported to XRIO files and imported to the WHMI. The WHMI can be used to write the settings to the protection relays. The WHMI can also be used to read the protection relay's setting parameters and to export those to files, which can be used by PCM600. WHMI imports all parameters from the import file except lockable and read-only parameters.
Note: The XRIO file name supports only characters A-Z, a-z and 0-9.
Note: The exporting and importing of settings is sensitive to the protection relay content. Settings are exported and imported for one protection relay at a time. The export files of a specific protection relay can be exchanged between PCM600, WHMI and the actual physical protection relay. To avoid errors and to efficiently manage the exporting and importing of settings, for example, in a substation with several relays, ensure that the names of the export files identify the relay to which the file should be imported.
CAUTION: Ensure that the correct settings are imported to the correct relay. Wrong settings may cause the relay to malfunction.

Click Choose File and choose the file to be imported.
Figure 1. Selecting the settings to be imported
-
Click Import Settings. Wait until the file transfer is complete.

-
Click Store to commit the imported settings to the relay. Wait until the import is complete.
Tip: Click Cancel to cancel the import. Both the WHMI and the relay revert to the settings in use prior to the import.

Tip: Only editable parameters are written to the relay during the import. If part of the import fails, the faulty parameters are listed separately.
