Editing Logical-Physical Links

You can use the Logical Mechanical Connection Editor dialog box to edit Logical-Physical Links; typically by creating or deleting logical interfaces for mechanical signals, and defining what mechanical signal should be connected to a logical interface.

This task shows you how to:

Create or Delete a Logical Interface for a Mechanical Signal
Connect or Disconnect a Logical Interface to a Mechanical Signal

Before you begin: You must have a model with Logical-Physical Links open in the Functional & Logical Design app.

Create or Delete a Logical Interface for a Mechanical Signal

You can create a logical interface for a mechanical signal, on the logical reference created from a mechanism in a Logical-Physical Link.

Note: You can jump Step 1 - Step 3 below if the link you want to edit is already displayed in the Logical Mechanical Connection Editor dialog box.

From the Behaviors section of the action bar, click Logical and Physical Models Mapping Edition .
The Logical Mechanical Connection Editor dialog box appears.
Note: There is a prefix to the dialog box name indicating the mode.
Select the mode:
The mode is indicated by the first part of the dialog box name:
- Kinematic
- Dynamic in Force
- Dynamic in Position
1. To go between kinematic (static) mode and dynamic mode:
  - If in kinematic mode, click Switch Kinematic to Dymamic Mode to go to dynamic mode.
  - If in any dynamic mode, click Switch Dymamic to Kinematic Mode to go to kinematic mode.
2. To go between the two dynamic modes (driven by force commands or by position commands):
  - If in dynamic mode driven by force commands, click Switch Force to Position Command to go to dynamic mode driven by position commands.
  - If in dynamic mode driven by position commands, click Switch Position to Force Command to go to dynamic mode driven by force commands.
Tip: The icons indicate the present mode.
Select the logical reference corresponding to the mechanism.
The data corresponding to the logical-physical link is displayed in the Logical Mechanical Connection Editor dialog box, the data of the mechanism to the left, and the corresponding logical reference to the right in the dialog box.
In the column Physical in the Logical Mechanical Connection Editor, right-click the mechanical signal you want to create an interface to.
The context menu of that signal is displayed.
Click Create Logical Interface in the context menu.
- A new logical interface is created on the selected logical reference/component, as well as under Interfaces of that logical component in the tree.
- The type reference corresponding to the mechanical type name is instantiated in the interface.
To connect the new interface to an interface of the logical component, right-click the port and select Create New Logical Connection.
Drag and select the port/component to be connected. See Creating Logical Connections.
Tip: You can delete a selected interface and the corresponding connection by selecting Remove Logical Interface .

Connect or Disconnect a Logical Interface to a Mechanical Signal

You can connect a logical interface of the logical reference created from a mechanism, to a mechanical signal.

If not displayed, display the Logical Mechanical Connection Editor dialog box for the link you want to edit. See Step 1 - Step 3 in the task above.

Important:

Selecting the right simulation mode is important since the mode works as a filter. As an example, if you have selected any dynamic mode and then select an existing logical-physical component, only dynamic logical-physical links are displayed in the editor dialog box.
It is possible to change the selected simulation mode when working in the editor to be able to redefine a logical-physical component. If you do this, be careful to redefine all connections using Step 3.

Double-click the logical interface in the Logical column.
A drop box with connectable interfaces (interfaces with the same direction) for the selected interface is displayed.

Depending on the available alternatives in the drop box, the alternatives might be selected:

Important:

If the logical type reference of a selection you do does not fit with the simulation mode selected, a message appears where you can click Yes to change the type reference to fit the mode, for example, change Length to Angle. If you click No, the type is unchanged.
When you use dynamic mode, you cannot mix the use of position commands with the use of force commands.

Select to select the current connected mechanical command. Nothing changes in the data model.
Select or (depending on input or output interface) to connect this mechanical signal to the interface. The logical type reference has a name corresponding to the mechanical connector type. If the interface is already connected to another mechanical signal, that signal is disconnected.
Select to select a mechanical signal that has not the same type as the interface. A panel is displayed where you can validate the typing modification. You can change all occurrences of the replaced type reference, which might resolve logical connection errors.
Select to disconnect the mechanical signal from the interface.
Notes:
- To disconnect all mechanical signals from the interfaces, select the button Delete the Logical Mechanical Mapping to the upper right of the Logical Mechanical Connection Editor dialog box.
- When all connections to interfaces are disconnected, the logical component is seen as unconnected - the corresponding Logical-Physical Link is broken.
