19.2
Logical Negation
NOT(_E)
These functions output the logical negation of input values.

Descriptions, types, and data types
Processing details
■
Operation processing
• These functions calculate the logical negation for each bit of the BOOL, WORD, or DWORD type data input in (s), and
output the operation result from (d) in the same data type as (s).
Ex.
When the data type is WORD
• A value input to (s) is the BOOL, WORD, or DWORD type data value.
■
Operation result
1.
Function without EN/ENO
The operation processing is executed. The operation output value is output from (d).
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
*1
When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
Operation error
There is no operation error.
