S7-400 over Industrial Ethernet CPs? 31 Introduction
1 Introduction
You can use the open communication through ISO-on-TCP connections for data
exchange by way of the Industrial Ethernet CPs of S7-300 and S7-400.
In this example an S7-300 is connected over the PROFINET interface of the
CP343-1 on the subnetwork 172.16.0.0. The S7-400 on the other hand is
connected over the GBIT interface of the CP443-1 Advanced on the subnetwork
172.16.0.0. The PROFINET interface of the CP443-1 Advanced is connected on
the subnetwork 192.168.99.0.
Configuration overview
Figure 1-1 shows an overview of the configuration.

Below we describe how to configure an ISO-on-TCP connection for sending and
receiving data by way of an Industrial Ethernet CP of S7-300 and S7-400.
2.1 Configuring CP343-1 and CP443-1 Advanced
2.1.1 Assigning IP addresses to CP343-1 and CP443-1 Advanced
The following IP addresses are used in this configuration.
Table 2-1

CP443-1 Advanced PROFINET 192.168.99.121 255.255.255.0
CP443-1 Advanced GBIT 172.16.49.99 255.255.0.0
Assign the IP addresses to CP343-1 and CP443-1 Advanced.
Follow the instructions below for assigning the IP addresses.

Table 2-2
No. Configuration step Note
1. Connect the SIMATIC Field PG on
which the configuration created with
STEP 7 is stored to the PROFINET
interface of CP343-1.
In Windows network settings
 LAN (Local Area Network) of the
SIMATIC Field PG you enter an IP
address that is in the same
subnetwork as that of CP343-1.
In this example the IP address
172.16.43.100 and subnetwork mask
255.255.0.0 are used for the
SIMATIC Field PG.
2. In the SIMATIC Manager you open
the STEP 7 project that contains the
configurations of S7-300 and S7-400
between which the data is to be
exchanged over an ISO-on-TCP
