Configuration with 1 subnet

Configuration example with a non-redundant control center
The following example describes a configuration with a non-redundant control center in
which all nodes are located in 1 IP subnet.
In this example, the DNP3 protocol is used; in other words, the stations are equipped with a
CP 1243-1 DNP3.
A configuration in which the IEC protocol is used would have the same setup apart from the
CP type (here CP 1243-1 IEC).
Figure 1-1
The S7-1200 stations are connected to the Internet via the CP and connected to the control
center.
When using the DNP3 protocol, for example, SIMATIC PCS 7 TeleControl or the system of a
third-party provider can be used as the control center. If you use SIMATIC PCS 7
TeleControl as the DPN3 master in the control center, you require the necessary DPN3
driver.
