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
s WORD starting 16-bit area to be extracted (source)
n INT specifies number of data to be extracted
d WORD 16-bit area for storing combined data (destination)
For Relay T/C Register Constant
s WX WY WR WL SV EV DT LD FL -
n WX WY WR WL SV EV DT LD FL dec. or hex.
d - WY WR WL SV EV DT LD FL -
Description
Extracts each lower 4 bits (bit position 0 to 3) starting with the 16-bit area specified by s and
combines the extracted data into 1 word if the trigger EN is in the ON-state. The result is stored in
the 16-bit area specified by d.
