Not (Negation in binary format)
Command
Negation on <value 1> in binary format (bit
reversal)
not (Negation)
*1. You cannot obtain a correct result with commands such as UB(1)  not UB(0).
Use "xor" command to reverse variables with bit data size as shown in the following examples.
• Example 1: UB(1)  UB(0) xor 1
• Example 2: UB(2)  X(00) xor 1
Note If an overflow or underflow occurs, the Drive Programming detects it as an error. Take neces-
 Example
Block number
1 Assigns 12 to U(03).
2 Assigns 65523 (binary: 111110011), which is the result of negation (bit reversal) on 12 (U(03)
binary: 00000110), to U(04).
3 Jumps to the block 3: loop_ unconditionally.
