Cautions
1) When handling 32-bit data in structured program, you cannot designate 16-bit device directly unlike the
simple project.
When handling 32-bit data, please use the label.
However, the 32-bit counter is a 32-bit long device, and 32-bit data can be specified directly.
When specifying the device, use the global label.
