Please refer to the specifications of each model for the

range of operands.

S1: Minuend S2: Subtrahend D: Subtraction result

S1 S2 D. The floating point value in S2 is subtracted from the floating point value

in S1 and the result is stored in D. The subtraction is conducted in binary floating point

constant into a

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

and the drive contact is ON,

When X0 = ON, binary floating point value (D1, D0) minuses binary floating point

value (D3, D2) and

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

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