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
s1 WORD starting 16-bit area for storing ASCII code (source)s
s2 ANY16 specifies number of source data bytes to be converted, and
how it is arranged
d WORD starting 16-bit area for storing converted result (destination)
For Relay T/C Register Constant
