As soon as several APUs (Active Power Units) are installed in the system, it is important to handle the sequence of the scan process as follows:

1. scanning of the master APU
2. scanning of all associated battery modules
3. scanning of the associated hardware components
4. scanning of the slave APU
5. scanning of all battery modules belonging to the slave APU

(from here on, steps 4. and 5. are repeated until the system has been completely scanned and the installation has been completed)

Currently, the ServiceApp is only designed for commissioning a system with only one master APU. If several master APUs are to be used, please use the conventional commissioning protocol instead of the ServiceApp.
