DINT
(1) Converts 32-bit floating decimal point type real number designated by to BIN 32-bit data, and stores the result at the
device number designated by .
(2) The range of 32-bit floating decimal point type real numbers that can be designated at +1 or is from -2147483648 to
2147483647.
(3) The integer value stored at +1 and is stored as BIN 32 bits.
(4) After conversion, the first digit after the decimal point of the real number is rounded off.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into
SD0.
Program Example
(1) The following program converts the 32-bit floating decimal point type real number at D20 and D21 to BIN 16-bit data, and
stores the result at D0.
