Mitsubishi Electric MELSEC iQ-R Series - NOT Operation

29 BOOLEAN FUNCTIONS
29.2 NOT Operation
29.2 NOT Operation
NOT(_E)
These functions output the logical NOT of input values.
Setting data
■Description, type, data type
*1 DX cannot be used.
Processing details
■Operation processing
• These functions perform a NOT operation (bit-by-bit) on the BOOL, WORD, or DWORD data type value input to (s), and
output the operation result, in the same data type as (s), from (d).
Ex.
Data type: WORD
• Input a BOOL, WORD, or DWORD data type value to (s).
■Operation result
1. Function without EN/ENO
The operation processing is performed. The operation result is output from (d).
2. Function with EN/ENO
The execution conditions and operation results will be as follows.
*1 If the value FALSE is output from ENO, the output data from (d) will be undefined. Create a program so that the undefined value will not
be used in operations.
Operation error
There is no operation error.
