D101: Since " " is not a numerical value, the conversion data, 0, is stored.
D102: Since "Length" is not a numerical value, the conversion data, 0, is stored.
D103: Since no element exists, the conversion data, 0, is added.
D104: Since "Temperature" is not a numerical value, the conversion data, 0, is stored.
D105: Since "-21" is a numerical value, it is converted to a binary value.
