Hello,

I am working in System Composer, and I am building a system architecture that can display real physical connections, with three components: one called a sensor, and the other called main control unit 1 and main control unit 2.

On real-world devices, the physical interface on the sensor is connected to both main control unit 1 and main control unit 2. I am currently only able to connect the physical interface on Component1 (sensor) to the physical interface on Component2 (main control unit 1), but I am unable to create a branch link to connect to Component3 (main control unit 2).

I would like to know how to solve this issue, besides creating an additional physical interface on component1, are there any other methods that can be implemented?

It seems that I need to create an additional virtual compoment in which Simscape model is called to implement the functions of BUS, and add multiple physical interfaces to the outer frame.

May I ask why designers do not allow physical links to create branches?

Hi @鑫鹏,

We added support for physical connector branching in R2022b.

In releases prior to that, the recommended workaround is to use a Simscape behavior to branch the connector (must have an interface assigned to the physical ports to branch in the behavior).
