You can have a CPU 22x with CP 243-1 communicate with other S7-200, S7-300
and S7-400 systems, as well as with an OPC server.
In this case, a maximum of 8 connections are possible in addition to a STEP 7 Mi-
cro/WIN connection (see Fig. 1).
Configuring and programming connections for S7 stations
In order to configure the communication between an S7-200 and an S7-300,
S7-400 or OPC server, you will require both STEP 7 Micro/WIN 32, version 3.2.1 or
higher, and STEP 7, version 5.1 or higher, with Service Pack 3 or higher (with NCM
for Industrial Ethernet) (see Chapter 4.5).
STEP 7 Micro/WIN 32 is used for configuring and programming the S7-200 station,
while STEP 7 with NCM for Industrial Ethernet is required for configuring and pro-
gramming the S7-300, S7-400 or the OPC server.
