Operands:
S
1
: Augend S
2
: Addend D: Addition result
Explanations:
1. S
1
+ S
2
= D. The floating point value in S
1
and S
2
are added and the result is stored in D.
2. If the source operand S
1
or S
2
is specified as constant K or H, the constant will automatically be
converted to binary floating point value for the addition operation.
3. S
1
and S
2
can designate the same register. In this case, if the instruction is specified as
“continuous execution instruction” (generally DEADDP instruction) and the drive contact is ON,
the register will be added once in every scan.
4. Flags: M1020 (Zero flag), M1021 (Borrow flag) and M1022 (Carry flag)
If absolute value of the result exceeds max. floating point value, carry flag M1022 = ON.
If absolute value of the result is less than min. floating point value, borrow flag M1021 = ON.
If the conversion result is 0, zero flag M1020 = ON.
Program Example 1:
When X0 = ON, add the binary floating point value (D1, D0) with binary floating point value (D3, D2)
and store the result in (D11, D10).

Program Example 2:
When X2 = ON, add the binary floating point value of (D11, D10) with K1234 (automatically
converted to binary floating point value) and store the result in (D21, D20).
