Figure 6: System overview of a large-scale PV power plant with a PowerPlantManager and SMADataManager (example)
This system overview shows an example of the setup of a large-scale PV power plant with a PowerPlantManager and
an SMADataManagerL (for communication via Internet, see Section4.3.1, page16). The PowerPlantManager
and the SMADataManagerL work together according to the master-slave principle. During this process, the
PowerPlantManager is the master, SMADataManagerL is always a slave. Multiple instances of
SMADataManagerL can be connected as slaves to one PowerPlantManager.
