Lookup table

For some data there is no appropriate scaling formula that can be applied so there needs to be a way to specify the conversion value for every possible raw byte value. This can be achieved by creating a conversion table.

The conversion table data can be imported and exported to make data entry a little easier. The import/export file must contain one table entry per line with the raw byte value (the values from 0 to 255) listed first on the line followed by either a comma or a space then the converted value listed last on the line.

If any raw byte values are missing from the imported file then they are automatically added and the converted value is set to equal the raw byte value. EFILive may not function correctly if ALL 256 values are not present.

Text
When the attribute is displayed as a "dashboard light" one of these three text descriptions will be displayed when the value:

  1. is below the alarm minimum.
  2. is between the alarm minimum and the alarm maximum inclusive
  3. is above the alarm maximum.

If at least one of these three values contains any text then the text will be displayed on the virtual dashboard in preference to the actual data value.

If ALL three of these values are blank then the actual data value will be displayed on the virtual dashboard .

Import
Use import to import a lookup table from an external file.

Export
Use export to export a lookup table to an external file.

Clear
Use clear to clear the conversion table.
