Notes on operand usage:
Please refer to the function specifications table for each device in
series for the scope of device usage
 S
1
: augend. S
2
: addend. D : sum.
 When the content of the register designated by S
2
is added to the content of the
register designated by S
1
, and the result is stored in the register designated by D .
Addition is performed entirely using binary floating-point numbers.
 If the source operand S
1
or S
2
designates a constant K or H, the command will
transform that constant into a binary floating point number for use in addition.

In the situation when S
1
and S
2
designate identical register numbers, if a
"continuous execution" command is employed, when conditional contact is On,
the register will perform addition once during each scan. Pulse execution type
commands (DEADDP) are generally used under ordinary circumstances.
 When X0=On, a binary floating point number (D1, D0) will be added to a binary
floating point number (D3, D2), and the results stored in (D11, D10).

DEADD D0 D2 D10
 When X2 =On, a binary floating point number (D11, D10) will be added to K1234
(which has been automatically converted to a binary floating-point number), and
the results stored in (D21, D20).
