Description

pict

Rotational ports are used to establish rotational mechanical connections between a schematic and the subschematic of a subsystem. If you copy a Rotational Port block into the schematic of a subsystem, a terminal will be created on the subsystem block. The name of the port block will appear as the terminal label. If you choose to hide the block name by unselecting the show name option in the block menu, the terminal label will also disappear.

Terminals can be moved around the edges of the subsystem by holding down the Shift key while dragging the terminal with the left mouse button or by using the middle mouse button.

Rotational Ports in a Top-Level Schematic

In the PLECS Blockset, if a Rotational Port is placed in a top-level schematic, the PLECS Circuit block in the Simulink model will show a corresponding rotational terminal, which may be connected with other rotational terminals of the same or a different PLECS Circuit block. The Rotational Port is also assigned a unique physical port number. Together with the parameter Location on circuit block the port number determines the position of the rotational terminal of the PLECS Circuit block.

For compatibility reasons you can also place an Rotational Port in a top-level schematic in PLECS Standalone. However, since there is no parent system to connect to, such a port will act like an isolated node.

Parameter

Port number
If a Rotational Port is placed in a top-level schematic in the PLECS Blockset, this parameter determines the position, at which the corresponding terminal appears on the PLECS Circuit block.
Location on circuit block
If a Rotational Port is placed in a top-level schematic in the PLECS Blockset, this parameter specifies the side of the PLECS Circuit block, on which the corresponding terminal appears. By convention, left refers to the side, on which also input terminals are shown, and right refers to the side, on which also output terminals are shown.
