SimMechanics First Generation ports include:
• Round connector ports
• Body coordinate system ports
SimMechanics Second Generation ports include:
• Frame ports
• Geometry ports
Port Location and Orientation on Subsystem Block
The orientation of the parent subsystem block and your choice of port location determine
the Connection Port block port location on the parent subsystem block.
• A subsystem is in its fundamental orientation when its Simulink signal inports
appear on its left side and its Simulink signal outports appear on its right side.
When a subsystem is oriented in this way, the actual port location on the subsystem
block respects your choice of port location (left or right) for the connector port.
• A subsystem orientation is reversed, with left and right interchanged, when its
Simulink signal inports occur on its right side and its Simulink signal outports occur
on its left side.
When a subsystem is oriented in this way, the actual port location on the subsystem
block reverses your choice of port location. If you choose left, the port appears on the
right side. If you choose right, the port appears on the left side.
