(S) (D)
MVN instruction inverts a channel data or a four-digit constant and
transfers it to a specified channel
Remarks
The MOV instruction is used to transfer 16-bit channel data or a
hexadecimal four-digit (16-bit binary) constant to a specified channel.
The MVN inverts the channel data and then performs the same function
as the MOV instruction.

if the transferred data are all 0, special auxiliary relay 1906 turns ON.
When the result register is logical 1 , a MOV or MVN instruction is
executed at each scanning. To execute it only once, programa
differentiating circuit for the input.
