◆
Function
The BIN instruction requires contact driving and has two operands. It converts the BCD value in S to a
BIN number. The result is stored in D. The instruction is generally used to convert the data (for example,
encoder disk setting) read by external ports to BIN data that can be directly used in operation.
The BCD value in S must be in the range 0 to 9999 in 16-bit operation or 0 to 99,999,999 in 32-bit
operation.
When the data in S is not in BCD format (Hex indicates any digit beyond the range 0 to 9), an operation
error will occur, and M8067 and M8068 are set to identify this error.
Example:
M8
ǒBIN K1Y0 D200Ǔ
When M8 is set, the BCD value in K1Y0 is converted
to a BIN equivalent. The result is stored in D200.

Function
The integer in S is converted to a oating-point number. The result is stored in D and D+1.
The constants K and H are automatically converted in all oating point operation instructions and therefore
cannot be used in the FLT instruction.
The INT instruction is the inverse function of FLT.
