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
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.
