I want to use PN Port of CPU to establish the redundant link Hello Anit I'm afraid to say that it is currently NOT possible (to be precise, it would be possible, but Siemens has not yet developed a Software redundancy package that supports this). While you can usePN 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? linkyou mentioned does also contain 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
