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.

R900B %MX0.900.11 for an instant the calculated result is 0.
R9009 %MX0.900.9 for an instant the result exceeds the range of 32-bit
data (overflow).
Description
Adds "1" to the 32-bit data specified by d if the trigger EN is in the ON-state. The result is stored in
d.
