When i try to define the connection i get the error message: "No corresponding CP exists on the local station" If i adda seperate CP343-1 moduleI can easily define a connection in NETPRO to the other ethernet stations. How can i configure this connection (TCP or UDP) and then use AG_SEND/AG_RECEIVE to communicate between the onboard-PN-port and other CPU's with CP343-1 modules?

J_Bell Posts: 5822 Rating: (412)	Dear Remark, referring your question I would say the following. You are right. It is not possible to configure a connection of any Ethernet Protocol from the CPU 31X with PN interface within NETPRO. But if you read the Manual of your CPU you will find the information that the Communication Connections of a CPU 319 PN are not configured within NETPRO but within a DB that has to be build a certain way. You also need to use so called T-Blocks to communicate, the use of FC 5 / 6 is not possible in this case. Please refer to the CPU manual to find more about it. Best regards J_Bell

Thanks for the quick reply!

Best regards, INS
