Hello Ebrahim_1

there's two ways you should be able to solve this:

1.) Use a seperate Ethernet port on your ibaPDA Server and connect PLC 2 to it.

2.) Routing is supported for S7 Analyzer as as of ibaPDA V6.28.0 (latest ibaPDA at time of writing is V6.31.3 and as always a free of charge download for registered iba users).
For this to work, you would route through PLC1 onto PLC2 but need to obviosuly have a physical Ethernet path from PLC1 to PLC2 and configureNetpro accordingly.
In the ibaPDA you then go to theI/O Manager, add a second S7 Analyzer TCP/IP connection and enter the routing information (Gateway PLC's IP address an S7 NetPro Subnet ID of target network).
Note: The devicesthat you route through must support routing, so check this first and see Which modules support the S7 routing function? for more on this.

I hope this helps
