designated by D; subtraction is performed entirely using binary floating-point
numbers.
 If the source operand S
transform that constant into a binary floating point number for use in subtraction.
 In the situation when S
"continuous execution" command is employed, when conditional contact is On,
the register will perform addition once during each scan. Pulse execution type
commands (DESUBP) are generally used under ordinary circumstances.
When X0=On, a binary floating point number (D1, D0) will be subtracted to a

binary floating point number (D3, D2), and the results stored in (D11, D10).

When X2 =On, the binary floating point number (D1, D0) will be subtracted from

K1234 (which has been automatically converted to a binary floating-point
number), and the results stored in (D11, D10).
