The data exchange has to be very small, so every solution is acceptable. We have difficulties in configuring the right parameters, because we are using the following components: S300 with: a)CPU 314 314-1AE03-0AB0 b)CP 342-5 342-5DA02-0XE0 2)S400 with: a)CPU 414-1 414-1XG01-0AB0 b)CP 443-5 BASIC 443-5FX00-0XE0 We kindly ask you to tell us exactly what are our options of realising this connection( ex with Bsend/Brcv, Put/Get, AG_Send/AG/Rcv, ...---considering the above mentioned components), and also to give give us some examples on how to do this. Looking forward to your answer. Best regards, Andreas

Dear Andreas, You can use the S7-400 as Client and Server for S7-communication, the S7-300 can only be Server for S7-connections. So that means that you can built up all S7-communication from the S7-400 (from the S7-300 is only answering = Server-function possible for S7-communication). With AG Send/Receive you can built up from both S7's, this is called a Profibus FDL link between both CP's in Netpro. You can also built up Global communication between the MPI-ports of both CPUs... See the attachment for all three differnet communications. Please consider that I have made it with STEP7 V5.4 SP2..... Attachment Forumcon.zip (904 Downloads)
	I hope that the answer will help, if you have still questions, don't hesitate to ask me. All the best, Late Never say never, think in solutions, not in trouble......
