Function
The MOV instruction requires contact driving and has two operands. It copies the value in S to D.
When the 32-bit instruction (DMOV) is executed, S and D use adjacent variable units with high-numbered
addresses.
For example, the statement [DMOV D1 D5] gets the result D1 -> D5; D2 -> D6.

DMOV C235 D42
When M0 = ON, the content of K4 is copied to D2. When M0 switches from ON
to OFF, the content (K4) of D2 remains unchanged, unless the user program
modifies the value in D2 again. The value in D2 changes to 0 when the PLC
switches from STOP to RUN or is powered on again. The value remains
unchanged when the registers with support for retention upon power failure are
powered on or switch from STOP to RUN.
