Red dotted line problem in simulink?

HI everyone!

I'm using Matlab 2019a and I tried to link two blocks, but I couldn't and I get a red dotted line. I want to make connections between SPDT and current measurement block.

Does anyone have any idea why it is not possible to do that connection?

Thank you

That because you are trying to connect to two blocks which belong to two different domains.

try PS-simulink converter or simulink-PS converter to make the connections.

otherwise try to find SPDT block which belongs to the same domain as other blocks or find the blocks which belong to same domain as the SPDT. Simply said see the colour difference.

This answer isn't helpful unless someone understands what this thing that you call a "domain" is.

Hi Tejas

i have tried already PS-simulink converter or simulink-PS converter as well. but did not work as you can see in attached file.

Is the current sensor for the same domain as Single Pole Double Throw Switch.

Hi Walter

yes, you can check the attached file

[Walter Roberson]

Your diagram has no powergui block, which is required for using sps blocks.

Your diagram appears to be missing an initialization block that defines X in order to run the mask icon initialization commands that have been defined for the CB* blocks.

Let's take it into simple. I would like to connect Solar PV with two resistive loads (as in the attached file). Everything is fine, but how it will be connected back into solar PV. Simulink-PS did not work. If you can do it, kindly attach an updated file. Thank you

connect blue blocks with blue blocks not with black
