3) If there are 3 or more , the exclusive logical sum is obtained using the "exclusive logical sum of
and " and .
If there is , the exclusive logical sum is obtained using the "exclusive logical sum of "exclusive logical
sum of and " and " "" and . In this way, the exclusive logical sum is obtained the
required number of times for all input labels …
Example: When the data type is bit
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.
Program example
In this program, the exclusive logical sum is obtained using each bit of word [unsigned]/bit string [16-bit] data
stored in devices specified in and , and the operation result is output to a device specified in
using the data type of data stored in devices specified in and .
