Explanation of function and operation
This function compares the contents of devices specified in
expressed as the bit type data to a device specified in
This function executes comparison [
a) This function outputs "TRUE" when in the case of "
b) This function outputs "FALSE" when in the case of "
Cautions
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.
