1. 1.Whichever the connection we use, is that required to do Net pro configuration on My partner PLC as well ( S7 400 H)? Please let me know, based on that I will have to confirm to my client as well.

Ø With that above configuration when I was trying to create S7 connection , it was not able to create with that CP 343-1 Lean. For testing purpose I have changed my CP to CP343-1 NOT Lean then I was able to create S7 connection. Which means CP343-1 lean will not Support S7 connection. Please let know is that correct?

Ø Since, both stations are under different project, while creating the S7 connections, I should select “Unspecified” for the partner side. Is that correct?

Ø Even though The S7 400 H station (Partner) is under different project, still I have to add my partner Hardware station under my project. Is that correct?

After I modify the Net Pro Configuration, when I download to my (PLC s7 300 ), will it get affect my partner PLC (S7 400 H ) because I have add and assign IP address for 400 H station as well under my project

Th Thank you very much your help in Advance.
