Expand configuration by adding HMI interface

Hey guys,

I want to expand my configuration by adding HMI interface - TP1500 Comfort. My supervisor want to achieve an architecture like in the attachment. Is it possible to add an TP1500 to a redundant link between CP modules? Does anyone tried this kind of configuration?

Thanks in advance.

Split from Problem with redundant HW Configuration - s7-300.

Anyone?

I'm still working on this case.

Hope to hear from you guys.
