Introduction
The S7-200 with CP243-1 supports the S7 communication as server and client, i.e. it’s possible to • • configure a client connection in the S7-200. So the S7-200 builds up active the S7 connection to the remote server. configure a server connection in the S7-200. So the S7-200 takes passive part in building up the S7 connection. The remote clientbuilds up active the S7 connection to the S7-200. The S7-200 provides the data as server.

For the S7-200 you have to configure the S7 connection in STEP 7MicroWIN with the Ethernet Wizard and for the S7-300 and S7-400 you have to configure the S7 connection in STEP 7. In this example in the S7-200, S7-300 and S7-400 respectively is used a PLC and a communication processor. You can alternative use aPLC with integrated Industrial Ethernet interface in the S7-300 and S7-400.
