AC450 I/O Redundancy

Hi Stefan,
Is it possible to connect redundant s800 I/O (Redundant AI845,AO 845) to AC450 through AF100 (Redundant CI522 and CI820)?
Also Can I connect redundant s800 I/O to ac450 through profibus dp ci840 and ci854?

AC450 does not support these new redundant I/O modules, like AI 845 & AO 845.

S800 I/O via profibus connected to AC450 is a bad idea, it's complicated to parameterize and not possible to change channel settings without to restart the complete bus.
The profibus interface for AC450 have the name CI541.

For AC450 you shall use CI820 for redundant AF100 slave stations .
