Connecting Models
Figure 4-9 uses the block diagram from Figure 4-5 but replaces the Tanks
input with Ht. As in Figure 4-5, the two valves are connected in series with
each other. In Figure 4-9, however, the two tanks now are appended to each
other.

Connecting Models in Parallel
A parallel connection creates a single model from two separate systems that
share common inputs. You also can use a parallel connection to add or
subtract outputs of two subsystems and represent them as a single output.
Use the CD Parallel VI to connect systems in parallel.
For example, consider the circuit system in Figure 4-10.
