Part III FP Instructions
F1_DMV
32-bit data move
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.
This instruction also exists as a P instru
ction (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.
