There are different types of wires in Flow Nodes, in thin wires only one value can flow downstream (towards the right), tho in double wires data can flow both down and up stream.

There are also thicker wires, they can send more than one value at a time in an array. Finally there is the lexicon wire, it can send a dictionary of data.

Copying two connected nodes, will also copy the wire.

In- and Out-lets

Wires are connected to a node via it’s in and outlets, this is the “arms” of the node.

Selecting a node, will show all of it’s in and outlets.

When wiring the only the compatible in and outlets of a nearby node will show.
