F42_BADD2
The 4-digit BCD equivalent constant or 16-bit area for 4-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#4321 (BCD)
Bit

s1
16# (BCD)
Example value 16#1234 (BCD)
Bit
15 . . 12 10 . . 8 7 . . 4 3 . . 0
s2
16# (BCD)
Result value 16#5555 (BCD) if trigger is ON
Bit
15 . . 12 10 . . 8 7 . . 4 3 . . 0
d

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.
