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.
Program example
In this example, either one among values stored in devices specified in … is output to a device specified
in in accordance with the value specified in using the data type of data stored in devices specified in
….
