Notes on operand usage:
Refer to the function specifications table for each device in series
for the scope of device usage.
 S
1
: addend. S
2
: augend. D: sum.
 Adds the content of the register designated by S
2
to the content of the register
designated by S
1
, and stores the result 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
converts 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 performs addition once during each scan. You generally use Pulse
execution type commands (DEADDP) under ordinary circumstances.
 When X0 = ON, adds a binary floating point number (D1, D0) to a binary
floating point number (D3, D2), and stores the results in (D11, D10).
X0
DEADD D0 D2 D10
 When X2 = ON, adds a binary floating point number (D11, D10) to K1234
(which is automatically converted to a binary floating point number), and stores
the results in (D21, D20).
