Hello duy; There was a discussion on a very similar project recently, you can look at the proposed solution here: http://support.automation.siemens.com/WW/view/en/17369594 Notice 2 things: 1- the application example uses an Ethernet CP for the S7-300 and S7-400 CPUs, but the text states that the same configuration can be used with an integrated Ethernet port, which is your case. 2- the example shows the S7-200 acting as client, the S7-300 acting as server. This implies that the S7-200 is the active partner on this connection, and that it reads and writes to the S7-300 client. The S7-300 cannot initiate the exchanges, or read from the S7-200. It must wait for the S7-200 to send data. Hope this helps, Daniel Chartier |

Hello duy; You could start by looking at the sample program proposed by J_Bell in the following thread: /tf/WW/en/Posts/22852 Hope this helps, Daniel Chartier |
