Data transfer within the PLC
F0_MV
The 16-bit data or 16-bit equivalent constant specified by s is copied to the 16-bit area specified by
Description
d, if the trigger EN is in the ON-state.
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.
Instead of using this FP instruction, we recommend using the related IEC instruction MOVE (see
page 59). Please refer also to Advantages of the IEC instructions in the online help.
