Kate,

I don't know why you're getting the 'cannot be added' error. That seems
strange. Do you still have the previous model of the same name open
or did you close it before you ran xpcsliface? When I've tried it,
I didn't have the tgmdlsimxpc model open from the previous try.
I created my model pairs in R2007b, the same version you said you're
using.

This isn't my area of expertise. Other members of the group could
help more since they know more about how its all implemented. Have
you been working through our tech support group? They should be
contacting the correct person in our group to help.

When I get busy, I may not check this newsgroup for a few days
so you will get better response by contacting tech support directly.

No, only one model with that name is open at one time (I only have 1 copy, which I've modified as you suggest).

Thanks for the tip, I will also consult with a Mathworks support engineer on this.
