Full Control Station Redundancy

A control stationcan consist of two fully redundant units (not AC500s), which are connected via a redundancy link. These control stations must ensure that only one of them at a time is actively connected to the substation and communicates with it. The inactive control station, however, can establish non-active connection with a substation and monitor it with keep alive packages.

	2 redundant Control stations (Not AC500)
	1 Substation with redundant Control station and 2 ETHERNET interfaces (2nd port)
	Redundancy link

Configuration at the control stations (not AC500)

The substation’s IP address must be specified at the control stations (1). 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).

Configuration at the substation (PM591-2ETH, PM595-4ETH, PM5650-2ETH)

Either the control station’s IP addresses or the general address 0.0.0.0 must be specified at the substation (2). For this, in the network settings of the substation enter the IP addresses of the control station (in the example: 192.168.1.10 and 192.168.2.11). Option Enable redundant connection must be enabled.

Note

If the general address 0.0.0.0 is used at the substation, no further control station on another substation can be configured on this controller. Equally, the substation connection must be activated for both interfaces.
