The node connection rules are based on the link type allowed between each node output and input. When you draw links between outputs and inputs, the UD plugin will prevent you from configuring the links to join incompatible inputs and outputs together.
In the Node Model detailed descriptions, each node model input and output has a link type listed. The table below summarises these connection rules in one place.
...
Example: from a roof node, you can connect the runoff output to a buffer, but not the runoff to tank output.

Figure 1 illustrates the connection combinations available on a Runoff link between a Roof node (origin) and a Tank node (destination).
A Runoff to Tank Rate and a Bypass Runoff Rate are output from a Roof node. These are mapped to a Tank node via the Runoff link between the Roof node and a connected Tank node.
Multiple connection combinations are supported by using the Add button.
