Inport/Outport are used as boundary blocks for a system. When used within a subsystem, they create inputs/outputs to the subsystem block that you can use to connect it with other blocks. When used at a model level, it can be used for at least two purposes:
- To import/export input/output signals via the Data Import/Export Pane.
- When generating code from the model, these serve as input/output signals that are supplied from other pieces of code.
