Description

With this structure, an exception is defined and can be entered into a list.

Structure Elements

Variable	Data type	Description
dateDate	DATE	Date where the exception was triggered.
todTimeStamp	TOD	Point of time where the exception was triggered.
udiModuleId	UDINT	ID of the module that triggered the exception.
sModuleName	STRING[80]	Name of the module that issued the exception.
etDiag	GD.ET_Diag	General, library-independent statement on the diagnostic. A value not equal to ET_Diag.Ok corresponds to an error message.
udiDiagExt	UDINT	Value of the POU-specific statement on the diagnostic. q_etDiag = GD.ET_Diag.Ok -> status message q_etDiag <> GD.ET_Diag.Ok -> diagnostic message
sDiagExt	STRING[80]	Name of the POU-specific statement on the diagnostic. q_etDiag = GD.ET_Diag.Ok -> status message q_etDiag <> GD.ET_Diag.Ok -> diagnostic message
sMsg	STRING[Gc_udiMaxStringSizeOfExceptionMsg]	Event-triggered message which gives more detailed information on the diagnostic state.
udiExceptionNumber	UDINT	Unique exception number in the structure XXXYYYY where XXX is the value of etSource and YYYY is the value of udiDiagExt.
stReaction	ST_Reaction	Reactions that are triggered by exceptions.
etSource	ET_ExceptionSource	Origin/source of the exception
xAutoQuit	BOOL	TRUE: The exception acknowledges itself.
wHmiAttributes	WORD	Can serve for communication with an HMI. Can be freely defined by the user.
timeDelayTime	TIME	Delay after which the reactions of the exception shall become active.
todElapsedTime	TOD	Time elapsed since the exception is active.
todReactionTimeStamp	TOD	Point in time at which the reactions of the exception became active.

NOTE: Error states difficult to diagnose now.

If you are using the xAutoQuit function with exceptions that have set a reaction in stReaction, the behavior of your application may be difficult to diagnose. If such an exception is triggered and then becomes inactive again, its reaction disappears again too. It is then only possible to understand why the system stopped by using the log data list (the effect depends on the influences of the chosen reaction).

Action recommendations:

Do not use the xAutoQuit function for exceptions where you have set a reaction.
