Question about Siemens S5-115 Rack

Hello,

I want to add an additional analog output module (8 A0 4...20 mA) to S5-115U in rack CR 700-3, but there are no free slots in CR 700-3 rack.
There is half slot used in slot 2 ( in slot 2 there is adapter casing for S5-135/155 modules, and there is DI module for S5-135/155). Can I use the unused half of the slot 2 to the analog output module assembly (S5-135/155 type such as 470-4UC12)?

I never tried, but when I think of the addressing methods of the 115 I would doubt it works.
a: The IO cards are automatically addressed according to place in the rack.
b: The IO cards are addressed with the IM(is it IM306?).
... hmm ... a doublette could perhaps work if it is one I and one Q -card.

You could try to ask the German guys here.

Btw, what is the MLFB of the adaptor?
