Description

A Subsystem block represents a system within another system. You create a subsystem in these ways:

Copy the Subsystem block from the Connections library into your model. You can then add blocks to the subsystem by opening the Subsystem block and copying blocks into its window.
Select the blocks and lines that are to make up the subsystem using a bounding box, then choose Create Subsystem from the Edit menu. Simulink replaces the blocks with a Subsystem block. When you open the block, the window displays the blocks you selected, adding Inport and Outport blocks to reflect signals entering and leaving the subsystem.

The number of input ports drawn on the Subsystem block's icon corresponds to the number of Inport blocks in the subsystem. Similarly, the number of output ports drawn on the block corresponds to the number of Outport blocks in the subsystem. If Inport and Outport block names are not hidden, they appear as port labels on the Subsystem block.

For more information about subsystems, see "Creating Subsystems" in Chapter 3.
