4.3 Fixed power
In AUTO and SEMI-AUTO mode, the ESS supplies the amount of power configured in the set point for fixed power.
The ASC can operate as a server to an external PLC/EMS controller. The ASC receives the fixed power set point from the PLC/EMS
controller using, for example, Modbus or analogue signals.
