uint64 status # Status flags

float32 battery_current # [A] Current into/out of battery. Positive for out. Negative for in. NaN: field not provided. float32 load_current # [A] Current going to the UAV. If battery current not available this is the DC current from the generator. Positive for out. Negative for in. NaN: field not provided float32 power_generated # [W] The power being generated. NaN: field not provided float32 bus_voltage # [V] Voltage of the bus seen at the generator, or battery bus if battery bus is controlled by generator and at a different voltage to main bus. float32 bat_current_setpoint # [A] The target battery current. Positive for out. Negative for in. NaN: field not provided

uint32 runtime # [s] Seconds this generator has run since it was rebooted. UINT32_MAX: field not provided.

int32 time_until_maintenance # [s] Seconds until this generator requires maintenance. A negative value indicates maintenance is past-due. INT32_MAX: field not provided.

uint16 generator_speed # [rpm] Speed of electrical generator or alternator. UINT16_MAX: field not provided.

int16 rectifier_temperature # [degC] The temperature of the rectifier or power converter. INT16_MAX: field not provided. int16 generator_temperature # [degC] The temperature of the mechanical motor, fuel cell core or generator. INT16_MAX: field not provided.
