4.5 Operating Mode: Faultless Operation
If there is neither a critical nor a non-critical failure and if there is a connection to the superordinate control unit, the
Modbus controller will change into the operating mode "faultless operation". The parameters will be transmitted
from the superordinate control unit to the Modbus controller and will be saved there. Subsequently they will be for-
warded to the electronic circuit protectors. The slot configuration data and slot parameters will be exchanged over
Modbus Register between the superordinate control unit and the Modbus controller.
4.6 Operating Mode: Bootloader
ControlPlex
®
