F6_DGT
The hexadecimal digits in the 16-bit data or in the 16-bit equivalent constant specified by s are
Description
copied to the 16-bit area specified by d as specified by n.
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.
Digits are units of 4 bits used when handling data. With this instruction, 16-bit data is separated into
four digits. The digits are called in order hexadecimal digit 0, digit 1, digit 2 and digit 3, beginning
from the least significant four bits:

n specifies the
destination hexadecimal digit position to be copied using hexadecimal data as follows:
