The block returns the bitwise complement of the input. All set bits of the input are reset and all non-set bits of the input are set.

Inputs, return value

	Identifier	→Data type
Inputs :	`IN`	`BOOL`, `BYTE`, `WORD`, `DWORD` or `LWORD`(corresponds to →generic data type `ANY_BIT`)
Return value:	–	`BOOL`, `BYTE`, `WORD`, `DWORD` or `LWORD`(corresponds to →generic data type `ANY_BIT`)

Input EN and output ENO are available when →calling the block. See "Execution control: EN, ENO" for information on input EN and output ENO.

Example for usage within ST-editor

PROGRAM Test
	VAR
		result1, result2 : BOOL;
	END_VAR
	result1 := NOT(TRUE);     (* The variable 'result1' evaluates to 'FALSE'. *)
	result2 := NOT(FALSE);    (* The variable 'result2' evaluates to 'TRUE'.  *)
END_PROGRAM
