Description When the execution condition is OFF, MOV(21) is not executed. When the exe-
cution condition is ON, MOV(21) copies the content of S to D.
Source word Destination word
Bit status
not changed.
Precautions TC numbers cannot be designated as D to change the PV of the timer or counter.
You can, however, easily change the PV of a timer or a counter by using
BSET(71).
Flags ER: Indirectly addressed DM word is non-existent. (Content of ∗DM word is
not BCD, or the DM area boundary has been exceeded.)
EQ: ON when all zeros are transferred to D.

Description When the execution condition is OFF, MVN(22) is not executed. When the exe-
cution condition is ON, MVN(22) transfers the inverted content of S (specified
word or four-digit hexadecimal constant) to D, i.e., for each ON bit in S, the corre-
sponding bit in D is turned OFF, and for each OFF bit in S, the corresponding bit
in D is turned ON.

Precautions TC numbers cannot be designated as D to change the PV of the timer or counter.
However, these can be easily changed using BSET(71).
Flags ER: Indirectly addressed DM word is non-existent. (Content of ∗DM word is
not BCD, or the DM area boundary has been exceeded.)
EQ: ON when all zeros are transferred to D.
