Name of the Member	Data Type	Description
OutputValid	BOOL	Output is valid. No errors.
ParameterError	BOOL	Parameter error: Init method's input i_pEventCode is null Inputs S_i_Forward and S_i_Backward are both true on same program cycle
StartUpError	BOOL	Input S_i_Forward or S_i_Backward is true on same program cycle than i_Enable rises.
Pin1ExternalVoltage	BOOL	Pin1 DO status is true(voltage in pin), longer than 60ms, when pin is not controlled.
Pin2ExternalVoltage	BOOL	Pin2 DO status is true(voltage in pin), longer than 60ms, when pin is not controlled.
Pin1ShortToGround	BOOL	Pin1 DO status is false(no voltage in pin), longer than 60ms, when pin is controlled.
Pin2ShortToGround	BOOL	Pin2 DO status is false(no voltage in pin), longer than 60ms, when pin is controlled.
Pin1CurrentLeak	BOOL	Pin1 current greater than product specific limit G_HBRIDGE_CURRENT_LIMIT_CONTROL_OFF, longer than S_i_CurrentDiagnosticDelay, when control is not active.
Pin2CurrentLeak	BOOL	Pin2 current greater than product specific limit G_HBRIDGE_CURRENT_LIMIT_CONTROL_OFF, longer than S_i_CurrentDiagnosticDelay, when control is not active.
Pin1OverCurrent	BOOL	Pin1 current greater than S_i_OverCurrentLimit, longer than S_i_CurrentDiagnosticDelay.
Pin2OverCurrent	BOOL	Pin2 current greater than S_i_OverCurrentLimit, longer than S_i_CurrentDiagnosticDelay.
InputLow	BOOL	i_Pin1Current or i_Pin2Current below zero.
InputHigh	BOOL	Not implemented.

Name	Numeric value	Description
Idle	0	Control request is zero. Control outputs are set to FALSE.
StartControl	1	Depending on the running direction, either Pin1 or Pin2 HS is controlled.
Control	2	Control continues until control request is zero or control direction changes.
EndControl	3	Wait motor stop.
ControlDisabled	4	Control is disabled.
Error	5	Error detected. Control outputs are set FALSE.
