Subtracts the content of the register designated by S
register designated by S
by D; subtraction is performed entirely using binary floating point numbers.
If the source operand S
converts 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 performs subtraction once during each scan. You generally use
pulse execution type commands (DESUBP) under ordinary circumstances.
When X0 = ON, subtracts a binary floating point number (D1, D0) from a binary
floating point number (D3, D2), and stores the results in (D11, D10).
When X2 = ON, subtracts the binary floating point number (D1, D0) from K1234
(which is automatically converted to a binary floating point number), and stores
the results in (D11, D10).
