Hi, I have a question is it possible to minimize the resources of S7 communication in NetPro when I am creating connection for the GET function on two PLCs.

I want  to use GET funcition on the PLC1 to reach data from PLC2, but also vice versa, to use GET on PLC2 to reach from PLC1 (I know I can use PUT instead, but that is not the question this time).

When I create the S7 connection in Netpro on the source (master, let's say) PLC1, I get the mirror connection on the partner PLC2, right? It is active in the PLC1, and not active on the PLC2.This is definitely necessary for the PLC1 to establish the GET transfer from PLC2 to PLC1, as we all know.

The question is, is this configuration enough for the vice-versa communication? I usually make another mirror-pair connection that is active on the PLC2, which I think is maybe not necessary, but I need a confirmation, please.

HI 

Yes it is possible see this 

i hope it is usefull for you.

How do you simulate communication between two CPU modules?

Hi Sandip,

I have just checked the example, and just to confirm.

Since the example from your link is showing hot to use the BSEND function, are you trying to tell me that the same applies to the GET?

Also, I have one additional important question: which ID to use on the PLC2 (partner port) when calling GET on it? I guess Partner ID, but just to check.
