5.5.4 NOT(_E)
Outline
This function obtains the logical negation of bits, and outputs it.
1. Format
*1. Output variable
2. Set data
In explanation of functions, I/O variables inside ( ) are described.
Explanation of function and operation
This function obtains the logical negation using each bit of bit/word [unsigned]/bit string [16-bit]/double word
[unsigned]/bit string [32-bit] data stored in a device specified in , and outputs the operation result to a
device specified in using the data type of data stored in a device specified in .
Example: When the data type is word [unsigned]/bit string [16-bit]
Cautions
1) Use the function having "_E" in its name to connect a bus.
2) When handling 32-bit data in structured programs, you cannot specify 16-bit devices directly, different
from simple projects. Use labels when handling 32-bit data.
You can specify 32-bit counters directly, however, because they are 32-bit devices.
Use global labels when specifying labels.
