GetBusError (FB)¶

FUNCTION_BLOCK GetBusError EXTENDS ETrigA

If IBus.GetBusState returns BUS_STATE.ERROR this function block returns the associated bus error code. The error codes are fieldbus specific and will be defined by the associated communication stack.

InOut:

Scope	Name	Type	Comment	Inherited from
Input	xExecute	BOOL	Rising edge: Action starts Falling edge: Resets outputs If a falling edge occurs before the function block has completed its action, the outputs operate in the usual manner and are only reset if either the action is completed or in the event of an error. In this case, the corresponding output values (xDone, xError, iError) are present at the outputs for exactly one cycle.	ETrigA
	xAbort	BOOL	TRUE: Action is stopped immediately and all outputs are reset to their initial values.	ETrigA
Output	xDone	BOOL	TRUE: Action successfully completed	ETrigA
	xBusy	BOOL	TRUE: Function block active	ETrigA
	xError	BOOL	TRUE: Error occurred, function block aborts action FALSE: No error	ETrigA
	xAborted	BOOL	TRUE : Action aborted by user	ETrigA
Input	itfNode	INode	bus node
Output	eError	ERROR	operation error code
	einBusError	ERROR_INFO	bus error code
