Using a Bus Junction
Bus junction
A signal bus can be split, or branched out, for extraction in any number of locations for a given sketch. In order to achieve this, simply use the Bus junction component in the Create Signal Bus menu item of the sketch contextual toolbar.
Note
Any changes to the source signals (inserted at the Bus creator) are transparently propagated downstream, and are automatically inherited by all the branches of the signal bus.
Since the creation point for a given bus is unique and spatially fixed, users are not exposed to any inconsistencies in signal value between the branches of a given bus.
