When one hexadecimal digit (4 bits) is shifted to the right,
hexadecimal digit position 0 (bit position 0 to 3) of the data specified by d is
shifted out and is transferred to the lower digit (bit position 0 to 3) of special data
register DT9014 (DT90014 for FP2/2SH and FP10/10S/10SH).
hexadecimal digit position 3 (bit position 12 to 15) of the 16-bit area specified by
d becomes 0.
This instruction is useful when the hexadecimal or BCD data is handled.
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
Shifts one hexadecimal digit (4 bits) of the 16-bit area specified by d to the right (to the lower digit
position) if the trigger EN is in the ON-state.
