S120 SLS function with PnozMulti

Hello all,and thank you in advance for taking attention to my demand:

For a new installation, we have to manage safety speed while doors are open on some axis S120.

This is how I suppose we can manage this solution, as we want to use the PnozMulti (no Profisafe):

-> Using F-DI/F-DO wired with PnozMulti

-> 1 License per axis using SLS is necessary. (extended safety functions)

Am I right?

So, is the TM54F mandatory?

Can we wire directly on CU320-2 F-DI and F-DO from Pnozmulti safety PLC?

Thank you for your answer.
