Configuration with a redundant control center

Configuration example with a redundant control center
The following example contains a configuration with a redundant control center and
connections via the Internet.
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 1-3
Addressing of the redundant DNP3 master
The two devices of the redundant DNP3 master in the control center are addressed by the
DNP3 CP using one DNP3 address but two different IP addresses.
