Using Simulink

Labeling Subsystem Ports

Simulink labels ports on a Subsystem block. The labels are the names of Inport and Outport blocks that connect the subsystem to blocks outside the subsystem through these ports.

You can hide (or show) the port labels by

• Selecting the Subsystem block, then choosing Hide Port Labels (or Show Port Labels) from the Format menu
• Selecting an Inport or Outport block in the subsystem and choosing Hide Name (or Show Name) from the Format menu
• Selecting the Show port labels option in the Subsystem block's parameter dialog

This figure shows two models. The subsystem on the left contains two Inport blocks and one Outport block. The Subsystem block on the right shows the labeled ports.
