jc_0171: Maintaining signal flow when using Goto and From blocks
You must maintain visual depiction of signal flow between subsystems.
You can use Goto and From blocks if:
You use at least one signal line between connected subsystems.
Subsystems connected in a feed-forward and feedback loop have at least one signal line for each direction.
Using Goto and From blocks to create buses or connect inputs to merge blocks are exceptions to this rule.
