Interface

Input	Data type	Description
i_xB07	BOOL	Most significant input bit
i_xB06	BOOL	Input bit
i_xB05	BOOL	Input bit
i_xB04	BOOL	Input bit
i_xB03	BOOL	Input bit
i_xB02	BOOL	Input bit
i_xB01	BOOL	Input bit
i_xB00	BOOL	Least significant input bit

Output	Data type	Description
q_etDiag	GD.ET_Diag	General library-independent statement on the diagnostic. A value not equal to ET_Diag.Ok corresponds to an diagnostic message.
q_etDiagExt	ET_DiagExt	POU-specific output on the diagnostic. q_etDiag = ET_Diag.Ok -> Status message q_etDiag <> ET_Diag.Ok -> Diagnostic message
