Module control measuring values
Depending on the configuration (number of slots for circuit protectors) five bytes input data with the status of
the circuit protectors (1 byte) and with the measuring values of load current and load voltage (4 byte) of the
corresponding circuit protector are made available.
Control of a circuit protector requires 1 byte output data.
In the event of a power module with 16 slots, 80 bytes input data and 16 bytes output data are exchanged.
Addressing will be in accordance with the configured slots N of the circuit protectors.
byte address [0…N-1] Status/Control.
byte address [N…4*N-1] measuring values.
