Part III FP Instructions
F190_MV3
Three 16-bit data move
Description
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.

To transfer two 16-bit data types, use either the F7_MV2 (see page 815) or
P7_MV2 instructio
n.
Variable Data type Function
s1, s2, s3 ANY16 source 16-bit area
d ARRAY [0..2] of
ANY16
destination, lower 16-bit area of 48-bit area
The variables s1, s2 and d have to be of the same data type.
For Relay T/C Register Constant
s1,s2,s3 WX WY WR WL SV EV DT LD FL dec. or hex.
d - WY WR WL SV EV DT LD FL dec. or hex.
The function copies three 16-bit data values at inputs s1, s2 and s3 to an ARRAY with three
elements that is returned at output d.
