F43_DBADD2
The 8-digit BCD equivalent constant or 32-bit area for 8-digit BCD data specified by s1 and s2 are
Description
added together if the trigger EN is in the ON-state. The result is stored in d.
Example value 16#12345678 (BCD)
Bit
31 . . 28 27 . . 24 23 . . 20 19 . . 16
s1
16# BCD
Example value 16#87654321 (BCD)
Bit
31 . . 28 27 . . 24 23 . . 20 19 . . 16
s2
16# BCD
Result value 16#99999999 (BCD) if trigger is ON
Bit

d
16# BCD
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.
