NOT

  • Library:
  • NOT block

Description

The NOT block implements the NOT ladder logic instruction. When the rung conditions are true, the block performs bitwise NOT operation on the values at source. The result of this operation is available at the destination port (dest).

Input

Controls the execution of the block. EnableIn reflects the rung state preceding the block. If the rung state preceding the block is false, EnableIn is false, the block does not execute and the outputs are not updated.

The input signal on which to perform the bitwise NOT operation. If the datatype is single (REAL – ladder logic equivalent), the input value is converted to int32 (DINT – ladder logic equivalent). int8, int16 (SINT,INT – ladder logic equivalent) datatypes are converted to int32 (DINT – ladder logic equivalent) by filling the upper bits with 0s.

Data Types: int8 | int16 | int32 | single

Output

expand all

By default, EnableOut follows the state of EnableIn. If the EnableIn input to the block is false, the logic implemented by the block is not executed and EnableOut signal is set to false.

Output signal resulting from the bitwise NOT operation. If the datatype is single (REAL – ladder logic equivalent), the resultant int32 (DINT – ladder logic equivalent) is converted to REAL (single – ladder logic equivalent).

Data Types: int8 | int16 | int32 | single
