Minimal Redundancy Structure

The most simple redundant structure with an AC500 consists of a redundant control station (not AC500) which is connected to the AC500 substation with 2 different IP addresses. These redundant control stations must synchronize which control station is active.

Only one control station can be active at any given time.

	Control station 1A (Not AC500)
	Control station 1B (Not AC500)
	Substation
	Redundancy link

Configuration at the control stations (not AC500)

The respective substation IP address must be specified at the control stations (1 and 2). For this, in the network settings of both control stations enter the IP address of the substation (in the example: 192.168.1.25).

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

Either the control station IP addresses or the general address 0.0.0.0 must be specified at the substation (3). 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 192.168.1.11). 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 can be configured on this controller for a further substation.
