Connecting Hardware Objects Using Commands

In a topology, you can create a hardware connection from several starting points.

You can create assembly connections from the context menus or from the topology view commands.

Important: To create a connection, the EE component port and the other element must have the same connector type or compatible types for a heterogeneous connection. The other element can be a channel, a topology, or a subsystem port.

The following scenario describes how to connect elements such as an ECU and a bus. The scenario is identical for:

  • Other EE components.
  • Wires.
  • Ports that are starting points.

Before you begin:
  • Create a topology with ports.
  • Instantiate in the topology, a channel, an ECU with ports, and two subsystems with ports.

  1. Right-click one of the following elements and select a corresponding connection command:
    ElementCommand

    No element in the diagram

    or

    Connections node of the topology

    		 Create Connection
    Topology Connect Topology
    ECU Instance Connect EE Component Instance
    Bus Channel Instance Connect Channel Instance
    Subsystem Instance Connect Subsystem

    Note:

    To connect a subsystem to another element, you can:

    • Create a physical channel instance placed at the top common hierarchical level of both elements.
    • Create a direct connection between them.

  2. In the connection dialog box, depending on your choice in the Source area, select the following elements in the Target area between:
    SourceTarget
    The topology and a port
    • An ECU and a port
    • A subsystem and a port
    • A bus
    An ECU and a port
    • The topology
    • A subsystem and a port
    • A bus
    A subsystem and a port
    • The topology
    • An ECU and a port
    • Another subsystem and a port
    • A bus
    A bus
    • The topology
    • An ECU and a port
    • A subsystem and a port

    Tips:
    • To create a direct connection between a topology port or an ECU, and a subsystem, see Connecting a Subsystem by Dragging.
    • To create heterogeneous connections, clear Hide ports or channels with different connector type.

    If the target port is connected to the topology through a bus, the bus is external.

The connection is added and appears under the Connections node of the topology and under the EE components, subsystems, or channels.
