Configuration example with connections over the Internet

The following example contains a configuration with a non-redundant control center.

In this example, the DNP3 protocol is used. A configuration in which the IEC protocol is used

would have the same setup.

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.

As an alternative to the router SCALANCE 812, you can also use a standard DSL modem

and establish the VPN connection with a security module SCALANCE S.

Addressing

Refer to the information in the section DNP3 / IEC (Page 63).
