SMC_NC_PrependDefaults (FB)¶

FUNCTION_BLOCK SMC_NC_PrependDefaults

This function block is used internally by |SMC_ReadNCFileFromStream| to prepend a sentence containing the given defaults, e.g. ‘N0 G17 F25 E1000 E-2000’. If |SMC_ReadNCFileFromStream| or SMC_ReadNCFile2 is used, there is not need to use this function block.

Important: this function block will prepend the defaults again after a jump command in the out queue. So it should be used before any buffering function blocks such the jump buffer. It should be called before SMC_NCNavigator as well, because the navigator will handle the jumps to unknown jump targets.

InOut:

Scope	Name	Type	Comment
Inout	sentencesOut	SMC_GSentenceQueue	The output sentence queue
	sentencesIn	SMC_GSentenceQueue	The input sentence queue
Input	bExecute	BOOL
	bAbort	BOOL	If TRUE, the current processing of this function block is aborted
	fDefaultVel	LREAL	Default velocity; used if the velocity (F-word) is not specified inside the CNC file.
	fDefaultAccel	LREAL	Default acceleration; used if acceleration (E+ word) is not specified inside the CNC file
	fDefaultDecel	LREAL	Default deceleration (E- word); used if deceleration is not specified inside the CNC file
	fDefaultVelFF	LREAL	Default velocity for fast forward (G0), FF word. It is used if no velocity is specified inside the CNC file.
	fDefaultAccelFF	LREAL	Default acceleration for fast forward (G0), EF+ word. It is used if no acceleration is specified inside the CNC file.
	fDefaultDecelFF	LREAL	Default deceleration for fast forward (G0), EF- word. A non-negative value is expected. It is used if no deceleration is specified inside the CNC file.
	b3DMode	BOOL	If TRUE, a G17 command (activation of 3D-mode) is executed implicitly.
Output	bBusy	BOOL
	bError	BOOL
	ErrorID	SMC_ERROR
	errorPos	SMC_NC_SourcePosition
