Figure 1-1 Communications partners
A CPU 22x with a CP 243-1 can communicate both with other S7-200, S7-300 and S7-400
systems and with an OPC server.
A maximum of 8 connections are possible in addition to a STEP 7 Micro/WIN connection.
Configuring and programming connections for S7 stations
To configure communication between an S7-200 and an S7-300, S7-400 or an OPC server,
you will need both STEP 7 Micro/WIN 32, version 3.2.3 or higher, and STEP 7, version 5.1
with service pack 3 or higher (with NCM for Industrial Ethernet).
The S7-200 station is configured and programmed with STEP 7 Micro/WIN 32. You will need
STEP 7 with NCM for Industrial Ethernet to configure and program the S7-300 or S7-400 or
the OPC server.
Data exchange via Industrial Ethernet
10 and 100 Mbps networks are supported in full and half duplex. The CP 243-1 also
supports the autonegotiation function for automatically negotiating the operating mode and
the transmission speed to be used. The mode and the transmission speed can also be
permanently specified by the user when configuring the CP 243-1. If the CP 243-1 does not
have a valid configuration, it uses "autonegotiation" mode as default.
