Hello,
I amusing step 7 ver 5.3 and I am trying to configure s7 connections betweenthe s7300 stations (each of them consists of a cpu314 and a cp343-1).

The problem is that, when I try to insert a s7 connection in "connection table, with the NetPro software the following message appears :

"no valid connection can be established between the local and the remote partners..."

There is no ones7 connection between the stations (the recources of the cpus and cps are not outweared).

I can insert a tcp/ip connection in the connection table, but i preffer to use s7 connections in my project.

Thanks in advance
