Multiple Control Stations on the same Network

As of firmware version 2.4, an AC500 can be used as a substation for several control stations. For this, the control stations must be distinguished by their IP addresses. Should a control station have more than one IP address (redundancy), both possible IP addresses should also be entered for the allocated substation connection. As a result, even despite being equipped with several ETHERNET interfaces, a device can only be one allocated control station at a time for a determined substation. Thus, several substations can be configured for different control stations on a AC500.

Control station 1
Control station 2
2 Substations (IEC60870-5-104 2:sup:nd Connection)

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

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

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

Both control station’s IP addresses must be specified at the substation (3). 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 192.168.1.11). Option Enable redundant connection must be disabled.
