Multiple Control Stations on different Networks

As of firmware version 2.4, an AC500 can have several local ETHERNET interfaces which can be used for separate control station connections. For this, a control station must be identified via its IP address. The substation address used locally is not used to distinguish a connection in order to enable a network and therefore route redundancy. On AC500, the acception of IEC60870-5-104 connections on an interface can only be prevented.

Control station 1
Control station 2
2 Substations with 2 ETHERNET interfaces (2nd port and 2nd connection)

Configuration at the control stations (PM57x-/ PM58x-/ PM59x-ETH, PM5650-2ETH)

The substation’s IP addresses must be specified at the control stations (1 and 2). For this, in the network settings of the control station enter the IP addresses of the substation (in the example: 192.168.1.25 and 192.168.2.26). Option Enable redundant connection must be disabled.

Configuration at the substations (PM591-ETH, PM595-ETH, PM5650-2ETH)

Both control station’s IP addresses must be specified at the substation (3) under both substation connections. For this, in the network settings of the substation enter the IP addresses of the control stations (in the example: 192.168.1.10 and 192.168.2.11). Option Enable redundant connection must be disabled.
