Instructions for adding output ports to subsystems are given https://www.mathworks.com/help/simulink/ug/connect-subsystems.html

Add Ports to Subsystems

To add ports to a Subsystem block directly, perform one of these actions:

• Click the edge of a Subsystem block. Then, select whether to create an input or output signal port, an input or output bus element port, or a connection port.
• [...]
• Drag a line from the edge of a Subsystem block. This action creates an output signal port.
