SMC_GCodeJumpBuffer (FB)¶

FUNCTION_BLOCK SMC_GCodeJumpBuffer

InOut:

Scope	Name	Type	Initial	Comment
Inout	ncprogIn	SMC_CNC_REF		CNC program input
Input	bExecute	BOOL		Rising edge starts operation.
	pBuffer	POINTER TO SMC_GCODE_WORD		Memory for internal buffer
	dwBufferSize	UDINT		Size of pBuffer
	pBufferOut	POINTER TO SMC_GCODE_WORD		Memory for ncprogOut
	dwBufferOutSize	UDINT		Size of pBufferOut in byte
	historyBuffer	SMC_ISentenceHistory		A function block keeping track of all G-Code sentence numbers that have been processed and removed from the jump buffer. If no buffer is provided, the default implementation SMC_MonotoneSentenceHistory will be used.
	udiRefillWindowSizePercentage	UDINT	10	The amount of elements that is read and removed in one cycle and added in the next cycle, when no jump has been requested (if ncprogOut.bRestart=FALSE). Provided in percent of the current buffer level and defaults to a minimum value of 10. A larger center window will slightly improve reading performance for long cycle times, while reducing the buffer’s chances to have a requested jump target actually buffered.
Output	bBusy	BOOL
	bDone	BOOL
	bError	BOOL
	ErrorID	SMC_ERROR
	ncprogOut	SMC_CNC_REF		CNC program output to SMC_NCDecoder
	bExecuteDecoder	BOOL		Set to TRUE as soon as ncprogOut is filled sufficiently to be interpreted by SMC_NCDecoder;
