Description

The Connection Label block lets you specify virtual connections between Simscape™ conserving ports, similar to the Goto and From blocks in Simulink® diagrams. These connection lines are nondirectional, which means that all sides of the virtual connection use the same type of block.

You can also use the Connection Label block to specify virtual connections between other types of nondirectional ports, such as Simscape Bus ports or Simscape Multibody™ frame, geometry, and belt-cable ports.

Virtual connectivity is established by the label name. If two or more Connection Label blocks in a model subsystem have the same label, then the conserving ports of other blocks connected to them behave as though they were physically connected. Virtual connections cannot cross subsystem boundaries.

The label name is displayed next to the block icon on the model canvas. You specify the label name by using the Label parameter.

Use the Connection Label block to reduce diagram clutter by breaking off tangled connection lines.

You can select a Connection Label block to highlight blocks related to it. To show a related block in an open diagram or new tab, pause on the ellipsis. Then, select Related Blocks Related Blocks button from the action bar. When multiple blocks correspond to the selected block, a list of related blocks opens. You can filter the list of related blocks by entering a search term in the text box. After you select a related block from the list, window focus goes to the open diagram or new tab that shows the related block.

Ports

Conserving

expand all

Conserving connection port. By default, this port is untyped.

You define the type of the port by connecting it to a conserving port of another block in the subsystem, or to a Simscape Bus port. Once you establish a connection, other Connection Label blocks that are in the same subsystem and have the same label can be connected only to the same type of port.

Parameters

expand all

Label name, which establishes the virtual connection. If two or more Connection Label blocks in the same subsystem of a model have the same label, then the conserving ports of the blocks connected to them behave as though they were physically connected.

The value of this parameter appears as a label next to the block icon on the model canvas.
