Part III FP Instructions
F14_PGRD
Program Read from IC card
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.

ST
When programming with structured text, enter the following:
IF start THEN
F95_ASC( s:= 'Prog1',
d_Start=> dummy_array[0]);
F14_PGRD( dummy_array );
END_IF;
