    Product profile simulation (booster simulation) can be useful for testing and pre-commissioning purposes. It is possible to simulate a booster profile when using a CIU 300 that is not connected to any product. The CIU 300 will behave as if a booster was connected on the GENIbus, even if that is not the case.
