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.

Variable Data type Function
d WORD 16-bit area for 4-digit BCD data to be increased by 1
For Relay T/C Register Constant
d - WY WR WL SV EV DT LD FL -
No. IEC address Set If
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 4-digit
BCD data (overflow).
Description
Adds "1" to the 4-digit BCD data specified by d if the trigger EN is in the ON-state. The result is
stored in d.
