Please refer to the specifications of each model for the

range of operands.

S1: Multiplicand S2: Multiplier D: Multiplication result

S1 xS2 D. The floating point value in S1 is multiplied with the floating point

value in S2 and the result is D. The multiplication is conducted in binary floating

point format

If S1 or S2 is designated as constant K or H, the instruction will convert the

constant into a binary floating point value before the operation

S1 and S2 can designate the same register. In this case, if the instruction is

specified as "continuous execution instruction" (generally DEMULP instruction)

and the drive contact is ON, the register will be multiplied once in every scan

When X1 = ON, binary floating point (D1, D0) multiplies binary floating point

(D11, D10) and the result is stored in (D21, D20).

When X2 = ON, K1234 (automatically converted into binary floating point value)

multiplies binary floating point (D1, D0) and the result is stored in (D11, D10).
