While you can use PN CPU's in general for a Software redundant system, you can only link the two via MPI, or external CP (Profibus or Ethernet). The Which modules can you use when implementing software redundancy? link contains a section for supported CP's and more info is also available in the manual (also available via the above link). I hope this helps
