F93_UNIT
Extracts each lower 4 bits (bit position 0 to 3) starting with the 16-bit area specified by s and
Description
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.
n specifies the number of data to be extracted. The range of n is 0 to 4.
The programming example provided below can be envisioned thus:
Source
Bit position
Array[0] at s
Array[1] at s
Array[2] at s
Destination
Bit position
Value at d
Bit positions 12 to 15 are filled with 0s.
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.
