Importing Data and Mapping for SKM

The tables below describe the information that is derived from the SKM Format file. There are three sources of data that are used to create the imported data in EasyPower:

  • Imported: Information that comes directly from the import file.
  • Calculated: Information that is calculated based on data in the import file or on the resulting item data.
  • Mapped: Information that is derived from mapping files that are compared with the imported data.

Please note the following:

  • For some items, the data may come from either the import or the mapping files.
  • The item ID is always imported.
  • The "To" and "From Bus" information may come from the import file or may be constructed based on how the graphic representation is built on the one-line.
