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 State Setting components and Bit State Switches 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 program in the following order:
The control process is as follows: Y0 ON/OFF Y1 ON/OFF (Step 2)
Y5 ON/OFF (Step 6).
Please note one point: When NB Unit receives the "Change window" command, it will directly
switch to the destination window while ignoring the component under the layer where this
component locates. As shown below, if Y2 is the function of "Change window", then Y3 to Y5
will be ignored. The number of the overlaid components can't exceed 32.
