Part III FP Instructions
F250_BTOA
Binary -> ASCII conversion
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
Converts 16-bit/32-bit binary data stored in the area specified by s2_BinaryData to ASCII code.
The conversion method is specified by n_ConversionMethod according to the four control
characters of s1_Control. The converted result is stored in the area specified by d_AsciiData.
