In the example shown in the figure below data should be exchanged between the PROFIBUS masters connected to Bus0 and Bus1. By configuring pairs of active slaves assigned to each other the master on Bus0 can send data to the master on Bus1 and vice versa. This is done by mapping the output data range of an active slave to the input data range of the respectively assigned slave.

Additionally in the example real external slaves exist in the PROFIBUS system of Bus0 (e. g. Remote IO stations, drives etc.). The output data sent by the master to these slaves can be sniffed and mapped to the input data range of an assigned active slave on Bus1. Sniffing existing slaves is only possible on Bus0.

In total up to 8 of these mapping assignments can be used in parallel. When using the additional license for extending the number of slaves (see chapter Order data) up to 16 mapping assignments can be used.

For further information on the mapping mode, see chapter Mirror mode.

Note
	In mapping mode, the ibaBM-DP device is operated without ibaPDA. It is only used to couple the PROFIBUS systems on Bus0 and Bus1. You cannot record data in parallel via ibaPDA.
