A function block used for logical negation. Sets an output value to the the logical inversion of the input.
In other words, the output will be:
- "1" if and only if the input is "0",
- "0" if and only if the input is "1".
Thus, the Truth table of the operation looks as follows:
| Value | Result |
| 0 | 1 |
| 1 | 0 |
Features
Using 'Negation' is equivalent to applying logical inversion to the value of any function block input or output.
