Output	Data type	Description
q_etDiag	GD.ET_Diag	General library-independent statement on the diagnostic. A value unequal to GD.ET_Diag.Ok corresponds to a diagnostic message.
q_etDiagExt	ET_DiagExt	POU-specific output on the diagnostic. q_etDiag = GD.ET_Diag.Ok -> status message q_etDiag <> GD.ET_Diag.Ok -> diagnostic message

Data type

Description

q_etDiag

General library-independent statement on the diagnostic.

A value unequal to GD.ET_Diag.Ok corresponds to a diagnostic message.

q_etDiagExt

q_etDiag = GD.ET_Diag.Ok -> status message

q_etDiag <> GD.ET_Diag.Ok -> diagnostic message

Data type	Description
STRING [25]	Status message of the FB_MultiBeltModule as a string.

q_etDiag	q_etDiagExt	Enumeration value	Description
OK	Ok	0	Ok
InputParameterInvalid	StateUnknown	32	Indeterminable state.
