SMC_PathCopierFile (FB)¶

FUNCTION_BLOCK SMC_PathCopierFile

The function block SMC_PathCopierFile reads and decodes a G-code file (sFileName) and creates an array of points from the generated path. If the number of path elements is smaller than the number of array points, then they are handled the same way as with SMC_PathCopierCompleteQueue. If not, the points are evenly distributed on the path. The inputs pvl and piStartPosition are transferred to the function blocks SMC_ReadNCFile and SMC_NCDecoder, so the documentation there is also valid for the inputs here.

This function block is used to provide an overview over a complete CNC program. It uses all points of the track buffer, but in case of very large G-code programs or a huge zoom factor it may be not precise.

InOut:

Scope	Name	Type	Initial	Comment
Input	bExecute	BOOL		A rising edge starts the function block
	udiNumberOfPointsInArray	UDINT	0	Number of points which are declared in pBuffer of the referred array.
	pBuffer	POINTER TO VisuStruct3DPathPoint		Pointer to the allocated array of points
	sFileName	STRING		CNC file name to be read
	pvl	POINTER TO SMC_VarList		Pointer to variable list (see SMC_NCReadNCFile2)
	piStartPosition	SMC_PosInfo		start position (see SMC_NCInterpreter)
	aSubProgramDirs	ARRAY [0..4] OF STRING(174)		An array of up to 5 directories where subprograms are searched (see SMC_ReadNCFile2)
	bParenthesesAsComments	BOOL	TRUE	If parenthesis should be considered as comments (See SMC_ReadNCFile2)
	bEnableSyntaxChecks	BOOL	TRUE	bEnableSyntaxChecks (see SMC_NCInterpreter)
	bStepSuppress	BOOL		When this input is TRUE, lines of the CNC program starting with ‚/’ will be ignored. Otherwise they will be processed.
	eOriConv	SMC_ORI_CONVENTION	SMC_ORI_CONVENTION.ADDAXES	Defines the way the orientation in the A/B/C words is interpreted (See SMC_NCInterpreter)
Output	bDone	BOOL		TRUE: FB completed
	bError	BOOL		TRUE: error during operation
	iErrorID	SMC_ERROR		Error ID
	vs3dt	VisuStruct3DTrack		Track output. To be setup as input of the visu element Path3D.
