577 +Charge/Discharge contactor has three algorithms of operation:
578 +
579 +* Dependent (on Charging and Discharging signals) - Charge/Discharge contactor depends on Charge and Discharge algorithms and their signals and behaves as Charging contactor if Charging signal is set, otherwise – as Discharging contactor;
580 +* Independent (Always) - Charge/Discharge contactor is always closed if there is no errors;
581 +* Independent (on Charge request or Discharge request) - Charge/Discharge contactor is based on its own controller that listen to Charge and Discharge requests.

590 +* Algorithm:
591 +** Dependent (on Charging and Discharging signals) - Charge/Discharge contactor depends on Charge and Discharge algorithms and their signals and behaves as Charging contactor if Charging signal is set, otherwise – as Discharging contactor;

594 +* Delay before starting charging or discharging, millisecond;
595 +* Delay before stopping charging or discharging, millisecond;
596 +* Control the precharging contactor – a flag that enables control of precharging contactor while closing the charge/discharge contactor;
597 +* Emulate the "Charging" and "Discharging" signals – a flag to enable generation of "Charging" and "Discharging" signals when closing charge/discharge contactor;
598 +* Errors 1, 2 to prevent CHARGING through charging/discharging contactor, Errors 1, 2 to prevent DISCHARGING through charging/discharging contactor – bitfields to choose the errors which will open the charging/discharging contactor. This bitfields are combined by bitwise OR and intended to separate settings for charging and discharging processes;
599 +* Errors 1, 2 which affect the contactor only if battery CHARGING is detected – a bitfield to choose the errors which will trigger only if charging current is present. This bitfield is combined with "Errors 1, 2 to prevent CHARGING through charging/discharging contactor" by bitwise AND;
600 +* Errors 1, 2 which affect the contactor only if battery DISCHARGING is detected – a bitfield to choose the errors which will trigger only if discharging current is present. This bitfield is combined with "Errors 1, 2 to prevent DISCHARGING through charging/discharging contactor" by bitwise AND;
601 +* Switch off the charging/discharging contactor on errors without delay – a flag to protectively open the charging/discharging contactor without a delay. In the opposite case, when an error is detected, the charging/discharging contactor opens always with the delay “Delay before stopping discharging”.
