F94_DIST
Divides the 16-bit data specified by s into 4-bit units and distributes the divided data into the lower
Description
4 bits (bit position 0 to 3) of 16-bit areas starting with d if the trigger EN is in the ON-state.
n specifies the number of data to be divided. The range of n is 0 to 4. When 0 is specified by n, this
instruction is not executed.
The programming example provided below can be envisioned thus:
Source
Bit position
Value at s
Destination
Bit position
Array[0] at d
Array[1] at d
Array[2] at d
Array[3] at d
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.
