Define method item sequence

Interface Items must be run. When an Interface Item is run, the data from the inlet streams in the calling model is copied to the corresponding inlet streams in the Composite Model. The data from the outlet streams in the Composite Model is copied to the corresponding outlet streams in the calling model.

Add a sequencer

Navigate to the Sequencers directory and open the Sequencers project. Add a SteadyState_Sequencer by dragging the sequencer from the Project Window to the Model window.
Sequence the method items to run the inlet Interface Item, then the two Flashes and finally the outlet Interface Item.
Click left on the sequencer to select the sequencer.
Press and hold the Shift key, point to node 0 (zero) on the sequencer (the cursor changes to a cross-hair) and press and hold the left mouse button down, drag a new node to the first item and release the left mouse button to drop a sequencing node on the first item.
With the Shift key still down, point to node 1 on the first item and press and hold the left mouse button down, drag a new node to the second item and release the left mouse button to drop a sequencing node on the second item. Continue for the next items.
