File position Designate the file position to start reading when binary
data reading is designated by (D0).
00000000H: Starting at the beginning of the file
00000001H to FFFFFFFEH: From the designated
position (The unit for the value is determined by word/
byte unit designation.)
FFFFFFFFH: Setting disabled
When CSV format read is specified at (D0)
• For the High Performance model QCPU of which
the first five digits of the serial number are "01111"
or lower, always set the beginning (0H) of the file.
• For the High Performance model QCPU/Process
CPU/Redundant CPU/Universal model QCPU/
LCPU of which the first five digits of the serial
number are "01112" or higher, set the file position
(Row).
00000000H: Read starts at the beginning of the file.
00000001H to FFFFFFFEH: Read starts at the
specified row.
FFFFFFFFH: Read continues, starting at the previous
read position.

When binary read is specified at (D0), always set 0.
When read data after CSV format conversion is
specified at (D0), set the number of columns from
where data will be read.

File name
character string
Designate the character string of a file name.
• When omitting an extension, also omit the "."
(Period).
• Limit the file name within 8 characters + period + 3
characters.
• When 9 or more characters are used, the extension
is ignored regardless of its presence, and "BIN" or
"CSV" is regarded as an extension.
