With NetPro , when I create a new connection type TCP I have the following error message:" there is not on the local station a CP appropriate " in french :« il n’existe sur la station locale aucun CP approprié » The RJ45 connector is only made it to the network PROFINET ?

Have a look at these two links which I trust will help: What are the commonalities and differences between configured communication connections and the open Ethernet communication? Wizard for creating connection data for open TCP/IP communication. (Open Communication Wizard) By the way, should your comms partner be another S7 PLC, I'd recommend to configure a so called S7 connection though and use GET/PUT, or BSEND/BRECV and/or USEND/URECV comms blocks.

I established the connection via a CP343-1 coupler but when using the integrated port to the 319F I can not connect. The FB65 TCON remains busy with a status 7002, what can be the problem?

Try to use the freeware wireshark (www.wireshark.org) to trace what is happening. You need for this a PC and a hun (or a switch where you can configure the monitoring port, like scalance X200 for instance).

Hello again autom25 Status 7002 means that it is "stuck" in trying to establish the connection (which you probably know already). The problem could be a misconfiguration on the S7 side but also on the partners side. Apart from edr's suggestions (which is good but requires a bit of protocol evalution skills), I'd suggest to trial a few things first. Have a look at the link below which has an expample project and also contains a Function (FC97) which can aid in trialingdifferent connection configurations (a Variable Table will of course work just as well, but by using this FC you can be sure that the connection parameters will be "harcoded" into the DB): How do you program the communication blocks FB63 "TSEND", FB64 "TRCV", FB65 "TCON" and FB66 "TDISCON" in order to use the TCP protocol for data exchange via the integrated Industrial Ethernet interface of an S7-300 or S7-400 CPU? I hope this helps and good luck
