The instruction converts the binary floating point value in S to decimal floating point value andstores the results in the register specified by D.2. PLC floating point is operated by the binary floating point format. DEBCD instruction is thespecific instruction used to convert binary floating point to decimal floating point.3. Flag: M1020 Zero flag, M1021 Borrow flag, M1022 Carry flagIf absolute value of the result exceeds the max. floating point value, carry flag M1022 = ON.If absolute value of the result is less than the min. floating point value, borrow flag M1021 = ON.If the conversion result is 0, zero flag M1020 = ON.Program Example:When X0 = ON, the binary floating point value in D1, D0 will be converted to decimal floating pointand the conversion result is stored in D3, D2.D0DEBCDX0D2D0D1D2D3BinaryFloating Point23 bits for real number, 8 bits for exponent1 bit for sign bit[D2] * 10 [D3]DecimalFloating PointExponent Real number Real number Exponent
