Arithmetic instructions
F23_DADD2
The 32-bit data or 32-bit equivalent constant specified by s1 and s2 are added together if the
Description
trigger EN is in the ON-state. The added result is stored in d. All 32-bit values are treated as double
integer values.
Example value 1312896

This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which
is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the
"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears
under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming
area to open the list of recently used elements.
Instead of using this FP instruction, we recommend using the related IEC instruction ADD (see
page 61). Please refer also to Advantages of the IEC instructions in the online help.
