In the Diagnostics tab, you see that ibaBM-DP runs in redundancy mode. In the top row Status on the Diagnostics tab, the current operating status of the device is displayed. In redundancy mode, you will see the following message:

In the example below, by means of two modules of the "Active slave" type, slaves with the addresses 22 and 100 have been generated. If you take a look at the diagnostics you see that both slaves were generated on both bus systems (bold margin shows that this slave is assigned to the chosen ibaBM-DP device). Moreover, you can see an "external" slave, in this case an ET200 station with the address 9. The master with the address 2 (each a S7-400H CPU) is displayed on both bus systems in magenta.
