SMC_PathCopier (FB)¶

FUNCTION_BLOCK SMC_PathCopier

The function block SMC_PathCopier is designed to visualize a queue currently used by the interpolator. It reproduces the content of the input queue poqCNCPath into its output path vs3dt. It processes all elements of the queue in the given order. In case of a linear element it adds only the start and end point to the path vs3dt. In case of curved elements it interpolates this element and adds n points to vs3dt. n depends on the length of the object and the input dPrecision. Processing is continued until the end of the queue is reached or until the track vs3dt is full and no more points can be added to. In the latter case, the function block waits until the first element has been deleted from the queue and hence the corresponding points can be deleted in vs3dt, too.

The function block is busy until the queue gets empty. It is typically used to display the next elements that are to be interpolated.

InOut:

Scope	Name	Type	Initial	Comment
Input	`bExecute`	`BOOL`		A rising edge starts the function block.
	`bAbort`	`BOOL`		`TRUE` aborts 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.
	`poqCNCPath`	POINTER TO SMC_OUTQUEUE		Pointer to `SMC_OutQueue` which describes the path.
	`dPrecision`	`LREAL`	1	Defines the precision of the track, meaning how many points should be computed for an element in the queue. A value of 1 indicates that a point should be calculated every 1 unit of the path. A value of 2 indicates that two points should be calculated for every 1 unit of the path.
Output	`bBusy`	`BOOL`		`TRUE`: FB is active
Output	`vs3dt`	`VisuStruct3DTrack`		Track output. To be setup as input of the visu element `Path3D`.
