How do you configure an S7 connection for data communication between an S7-200 and an S7-300 or S7-400 on the Industrial Ethernet?
The S7-200 with CP243-1 supports S7 communication as server and client, which means it is possible
- To configure a client connection in the S7-200. That means the S7-200 actively sets up the S7 connection.
- To configure a server connection in the S7-200. That means the S7-200 is passively involved in setting up the S7 connection. The remote client sets up the S7 connection to the S7-200. It provides the data as a server.
The configuration of the S7 communication for the S7-200 takes place in STEP 7 MicroWIN with the Ethernet Wizard. The configuration of S7 communication is carried out in STEP 7 for the S7-300 and S7-400.
Proceed according to the following instructions when configuring S7 communication between the S7-200 and the S7-300 or S7-400:

- In this example, a CPU and a communication processor are used in the S7-200, S7-300 and S7-400. Alternatively, you can also use a CPU with an integrated Industrial Ethernet interface in the S7-300 and the S7-400.
- The CP343-1 Lean only supports S7 communication as a server; that means
that if you use a CP343-1 Lean in the S7-300 station, configure the S7-300 station as a server and the S7-200 station as a client for S7 communication.
