Editing the Excel template
The Excel file has two register sections that you can choose from depending on how host system queries
are specified.
The register section that you will use must be placed at the beginning of the spread sheet, and there
must be at least five empty rows after the register section. Information after the five empty rows will be
ignored by the script that creates the new *.ini file.
Once the Excel file is ready, press the Export to map file... button. Then a new register map *.ini file is
created which can be uploaded vi the system hub’s web graphical interface (see “Upload and download
register map file” on page 199).
Make sure that there are at least five empty rows after Section End.
Register number section
One of the register sections is based on a list of separate register numbers as illustrated in Figure F-2. This
will be suitable in case the host system requests data for one tank at a time.
The page lets you edit existing registers and add new registers.
Once editing is done, you will have to verify that Section Size is correct. Section Size is automatically
calculated and refers to the number of registers based on the first and last register in the list. In the
example shown in Figure F-3, Section Size is equal to 22.
Enter number of tanks in the Section Range field (16 in the example shown Figure F-3).
