Conversion variable
■Processing procedure
C24 processes conversion variable according to the following procedure.
• When "Conversion" is 'HEX  ASCII hexadecimal' or 'ASCII hexadecimal  HEX'

Adding
a delimiter
"00001234,"
When "Delimiter" is ' , '

Comma,

When "Delimiter" is ' , '
"00001234,"→"00001234"
Blank-padded characters
When transmitting data, upper digits are filled with the data specified in "Blank-padded character" when the number of digits is
less than that specified in "Number of Send Digits of Data".
When receiving data, either '0' or '_(space)' is processed as a blank-padded character regardless of the specification in
"Blank-padded character".
Ex.
Setting of "Number of Send Digits of Data" is '6' ('_' indicates a space character in the table)
Received data Operation of C24
000120 Considers the first 3 digits as blank-padded characters.
_ _ 0120 Considers the first 3 digits as blank-padded characters.
0 _ 0120 Considers the first 3 digits as blank-padded characters.
_ _ _ 120 Considers the first 3 digits as blank-padded characters.
Considers it to be an ASCII  BIN conversion error (7F20H).
00012 _
Considers it to be an ASCII  BIN conversion error (7F20H).
_ _ _ 12 _
Considers it to be an ASCII  BIN conversion error (7F20H).
