[?]: S7-fault tolerant via 3com Switch.

S7-fault tolerant via 3com Switch
Show
Hello Dear Colleagues!
I have two questions about my future project.
In this project I have PC-server with two CP1613 and S7-Redconnect software. Also I have two CPU412-3H and two CP443-1 installed as typical S7-400H system.
I have already configured s7-fault tolerant connection between PC-server and H-PLC in NetPro. At this point everything is ok.

In project PC and H-PLC are connected to Ethernet-switch MOXA (managed, typical 3COM industrial switch). This Swith doesn't support ISO-protocol which is required for s7-fault tolerant connection.

Q1 :?:

Should I expect problems with s7-fault tolerant connection between PC and H-PLC via MOXA?
What parameters should I set to get connection without any problems between H-PLC and PC?
Maybe it is enough to set «IP protocol is being used» in properties of CP443 and CP1613?

Q2 :?:

Also it is necessary to organize connection between CPU412-3H from Q1 and PLC based on CPU315 and CP343. PLC is located near of H-PLC.
I need most simple way to connect H-PLC and PLC with minimal software and hardware changes in PLC.
Please watch attached file with structure. Is it Ok? remarks?
I plan to download program from PG to H-PLC and PLC via Ethernet.
The problem is actual.
Somebody had a similar problem?
thx.
