Is there such a thing as a Physical Signal Bus

It sure would be handy to be able to put seveal physical signals into bus. Large systems get messy. Is there such a thing as a physical signal bus? I haven't seen one yet.

[Vasco Lenzi]

Simscape bus have been introduced in R2018b, which was released September 2018!

See Simscape Bus in the online documentation.

You can combine domains:

You can use it for Simscape Multibody connections (can also include other domains):

The Simscape Bus does not work with physical signals according to the online documentation:

"It does not work with other types of connections, such as physical signal lines [...]".

Is there an alternative bus that does?

[Michael Williams]

I am wondering if this functionality has been included in any newer versions? A physical signal bus would be very helpful.

As previously mentioned, there is a Simscape bus available, but it functions only with standard bi-directional physical connections and does not support physical signals. There is a PS Three-Element Demux in Simscape foundation library:

In Simscape Electrical there are a few built in blocks that can be used with converters.

If these blocks are not answering the specific requirements, the solution is to create your own mux and demux blocks for simscape physical signals.

[Michael Williams]

This is helpful. I assume we can customize the demux / mux code to handle additional inputs / outputs. Is there a limit to how many elements can be combined?

[Sabin]

There is no strict limit; however, adding too many elements can make it increasingly difficult to distinguish between all these connections in the Simulink file.
