Cable Merge Copernicus node

Combines two cables into one cable.

On this page	Parameters Inputs Outputs
Since	21.0

This node lets you wire in two cables and output them as a single cable. The Operation parameter determines how the two cables merge to form the structure of the output cable.

This node is useful in network management to organize different cables. For example, use this node to ensure that an incoming cable has a specific structure.

See Cables for information about how to use this node.

Parameters ¶

Operation

The method used to combine the two input cables into one output.

Union

The output cable contains every wire in the first cable, followed by every wire in the second cable that’s not already in the first cable.

Intersection

The output cable contains every wire that’s in both cables. A wire’s data comes from the first cable if it’s present in both cables.

Difference

The output cable contains every wire in the first cable that’s not in the second cable.

Copy

The output cable’s structure matches the second cable. To form this cable, data is preferentially taken from the first cable. Wires that don’t exist in the first cable instead carry data from the second cable.

Full Union

The output cable contains every wire in the first cable, followed by every wire in the second cable. This is similar to Union, but doesn’t avoid the duplication of wires.

Rename

The output cable contains the first cable’s data, but is named according to the wires of the second cable. If the second cable has fewer wires than the first cable, the output is truncated to that size.

Inputs ¶

input_cable

The first cable.

reference

The second cable.

Outputs ¶

merge

The combined cables.
