Explanation
1. This instruction converts thee single-precision floating-point number in the register specified by S into the decimal
floating-point number, and stores the conversion result in the register specified by D.
2. The floating-point operation in the PLC is based on single-precision floating-point numbers. Use the FBCD
instruction to convert a single-precision floating-point number into a decimal floating-point number.
3. Instruction flags: SM600 (zero flag), SM601 (borrow flag), and SM602 (carry flag)
When the absolute value of the conversion result is larger than the value that can be represented by the maximum
floating-point number, SM602 is ON.
When the absolute value of the conversion result is less than the value that can be represented by the minimum
floating-point number, SM601 is ON.
When the conversion result is zero, SM600 is ON.
