Hi. I´m using SIMULINK on Matlab r2013a.

I would like to understand why some wires of my model are red.

Can you help me?

This happen when two block can not be connected. Maybe you are using simscape where certain component can not be directly connected.

No. I can connect eveything . The model is working but only now I noticed that some wires of the model are red. Why?

[David Sanchez]

But were they red from the beginning, when you set the model, or did they turn red after running the model?

Perhaps you have sample-time colors enabled?

This problem happened with me also I was trying one example from the mathworks documentation and after running the model connection between the lookuptable and stateflow chart became red.But yeah I can view the output.I don't know why

[Shivashis Sahoo]

Okay yes you were right ! @Kaustubha Govind It was due to sample-time in my case , I had the colors enabled. Thank you so much.
