■ CSV Format
The CSV format is a data format (using comma delimiters) that is specified by
ladder instructions, READ DATA FILE (FREAD(700)) and WRITE DATA FILE
(FWRIT(701)), in the CPU Unit. The CSV format is configured according to
the specified FREAD(700) and FWRIT(701) parameters, as follows:
If word data from the I/O memory (1234 hexadecimal, 5678 hexadecimal, up
to DEF0 hexadecimal) is contained in an attached file in CSV format, the word
data will be converted into ASCII format in word or double-word units. The
words are delimited by inserting comma delimiters (',':2C), and CRs after
specified fields ([CR][LF]: 0D0A).
Example: Data format using words delimited by commas with CRs after every
10 fields.
