To use the mirror mode, set the rotary switches as follows:

• S1 = 6 and S2 = 0 for mirror mode with compatibility mode 32Mbit

• S1 = 6 and S2 = variable 1…F for mirror mode with 32Mbit Flex

If you want to use the mirror mode, you need an additional license (order data see chapter Order data).

The mirror mode option is ideal for modernizations in which a new control system is to run in test mode parallel to the current system. With a PROFIBUS connection, ibaBM-DP is coupled into the original PROFIBUS line. The second connection is connected to the new control system. ibaBM-DP mirrors and simulates the slaves from the original line to the parallel system. The input data are also copied. This way, the new controller can be tested in parallel with the original slaves and real input data. Signals from the original and parallel system can be recorded and compared simultaneously with ibaPDA using the sniffer function.
