On how to use the Two-Way Connection Block

So I recently noticed the existence of the Two-Way Connection block. I would like to use it to reduce the number of signal connectors in my models.

Is there any example using this block?, I've been looking and no luck yet.

Maybe we should start with your need to "reduce the number of signal connectors". Can you provide more specifics? My understading is that this two-way connection block reduce connection for a quite particular purpose (like coupling two physical systems). It may not be what you have in mind.

I was considering using it to connect bus signals going out and coming from components. I haven't checked yet if this is possible, but I think it would be useful. My question surrounds the fact that I haven't seen this block used by users or in any Mathworks examples. Thus, I hoped to get some indications of its pre-defined purpose implemented in a model, preferably one from Mathworks.

Hi @CAME,

I've seen this in earlier version of Powertrain Blockset examples. I took some snapshot from this "Conventional Vehicle Reference Application" in R2021a.

In the physical model of the vehicle, built in Simulink, you may find some use of this two-way connection.

Hope this helps.
