The parameter export and import function can be utilized, for example, when the merging unit parameters are set using the WHMI instead of PCM600. The merging unit 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 merging units. The WHMI can also be used to read the merging unit 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 exporting and importing of settings is sensitive to the merging unit contents. Settings are exported and imported for one merging unit at a time. The export files of a specific merging unit can be exchanged between PCM600, WHMI and the actual physical merging unit. To avoid errors and to efficiently manage the exporting and importing of settings, for example, in a substation with several devices, ensure that the names of the export files identify the merging unit to which the file should be imported.
CAUTION: Ensure that the correct settings are imported to the correct merging unit. Wrong settings may cause the merging unit to malfunction.
Tip: Only editable parameters are written to the protection relay during the import. If part of the import fails, the faulty parameters are listed separately.
