I suggest taking Core 1 training.

You have controls, indicators, and diagram constants.

• You can change the value of a control at runtime. It is a data source for a wire
• You can read a value from an indicator, it is a data sink of a wire
• A diagram constant is a data source that only lives on the block diagram and cannot be changed when the VI is running. Useful for things that never change. (e.g. to multiply with pi, pi should probably not be a control)

The wire is the data and each wire can only have exactly one data source, but it can be branched to as many indicators or functions you want!

You can right-click a terminal or diagram constant and change to to a control or indicator and vice versa.

it's because the channel is a constant , therefore it will not be shown in the front panel, If you want to see it , right click on the constant of the channel and find the option Change to Control.
