Wonderware multi PLC communication

Hello,

In Wonderware System Platform you can configure communication to several PLCs in different ways, and I am interested which is "best practice"?

Let's say we have 1 PC and 10 PLC. Each PLC has 2 update intervals. Config options:

1. In SMC - One instance of SIDIR server with 10 nodes configured. Each node has 2 Device Groups. In ArchestrA - One DDESuiteLinkClient with 10*2=20 topics configured.
   
2. In SMC - One instance of SIDIR server with 10 nodes configured. Each node has 2 Device Groups. In ArchestrA - 10 DDESuiteLinkClients each with 2 topics configured.
   
3. In SMC - 10 instances of SIDIR server each with 1 node configured. In ArchestrA - 10 DDESuiteLinkClients each with 2 topics configured.

I use 1st option, but it's pain in the neck to configure 20 topics in small window of DDESuiteLinkClient, so I've thought maybe I'm doing something wrong...

TL/DR: How do you guys configure multi PLC communication in Wonderware?

@Techuser: It´s better if you create a new thread.
Answering your question , one way to do it is to send data from one plc to the other, no experience with Mitubishi , maybe sendind a message.
If using scada, you can try using derivated tags, i.e. pass data from one plc to another thru scada.
@Anytech, I guess that using an OPC server UA or DA you can get all info from your PLCs. you did not mention if all your plcs were same brand or not.

thanks my friend
