About the overlay of component
Overlaying the multiple components together can realize many special functions. NB Unit
supports the overlay of multiple components. When these components are triggered, the
program will perform the corresponding operations according to the layer sequence, i.e. the
component on the top layer will be triggered firstly, then the component in the 2
triggered and so on. For example, if 6 Bit Switch components are overlaid together to control
the Y0 (top layer) to Y5 (bottom layer), then when these components are triggered, the NB Unit
will execute the functions in the following order:
The control process is as follows: Y0 ON/OFF Y1 ON/OFF (Step 2)
Y5 ON/OFF (Step 6).
However, if the overlaid components include the function key of changing screen, the screen is
changed so that the other component behind the function key by are also unable to be
operated by the function. Therefore, the function key of the changing screen should be
arranged at the behind of all the component.
