Faulty ConfigurationΒΆ

Note

This configuration does not work!

If an AC500 is configured as a control station, the interface which is used to reach the substation is not defined.

The decision as to which interface is used for this is taken by TCP/IP when running.

It is also dependent on the current network configuration.

Here, the current link status and the order of link recognition may be decisive for the interface to be used.

Such a scenario would not result in stable communication as both substations cannot clearly distinguish the control stations.

Instead, the connection management for a substation will assume that the control station has lost the connection and then establishes a connection.
