determined by (d1)+7.)
• FFFFFFFFH: Cannot be specified.
■
When "Reading data after converted to CSV format" is specified by (d1)+0
• 00000000H: From the beginning of the file
• 00000001H to FFFFFFFEH: From the specified row
• FFFFFFFFH: From the position where the previous reading ends
00000000H to
FFFFFFFFH
