Redundant network

Hi

I want to configure a Redundant industrial network, with 12 PLC S7-400F, 4 PLC S7-400FH , 1 WinCC Server with 2 network and 2 WinCC client.  I have read the following documents:

CommunicationManual_e.pdf

S7-400H_e.pdf

mn_osm-esm_76.pdf

I configured the network like the attachment file in two ways. Please tell me if they are correct.and witch one is better?

Another question is which softwares do I need to managment this network?

Thanks

Dear Mehrnoush

I saw your redundant configuration and I think the second configuration is better because you have design a ring that could increase your availability of your network, and I prefer to connect my CLIENTS to different ESMs but I think it will be better to use OSM instead of ESM because of advantages of Optic communication.

There is some soft wares likes SNMP OPC server that can manage your Ethernet network but I think intrinsically you do not need any special software for this.

best regards
