Could CRP93200 be used to run two separate networks on CRA93100

Question:
Could CRP93200 be used to run two separate networks on CRA93100?
What is the behavior of cable diagnostics registers then?




Answer:
Yes, the architecture is justified in  Modicon Remote I/O Cable System Planning and Installation Guide
as attached.(attach1.png)
However It is the excepted  that the cable diagnostics registers behaviors differently with the situation where CRP93200 is used along with CRA93200 because we reverse the cable connection by one branch in the CRA93100 case.

Take the drop2 for instance.
If the CRA93100 is connected under  cable A of CRP93200
%SW549 has no change in the value while the value of %SW550 low byte is changing continuously
If the CRA93100 is connected under  cable B of CRP93200
%SW549 high byte is not changing while its low byte is changing continuously
%SW550 high byte is changing continuously while its low byte is not changing
