Part III FP Instructions
F52_BDIV
4-digit BCD division, destination can be specified
The quotient is stored in the area specified by d and the remainder is stored in special data register
DT9015 (DT90015 for FP2/2SH and FP10/10S/10SH).

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.

Description
The 4-digit BCD equivalent constant or the 16-bit area for 4-digit BCD data specified by s1 is
divided by the 4-digit BCD equivalent constant or the 16-bit area for 4-digit BCD data specified by
s2 if the trigger EN is in the ON-state.
