did you create a connection in NETPRO? 

where did you get LADDR for sfc15?

Of course there will be a stop controller - two masters on one profibas can not exist

Here is an example on TCP/ip  how to make a connection, and then it is loaded into all controllers, in your case in all three you have the H system.

on the profibas system is done similarly.
