SMC_SegmentAnalyzer (FB)¶

FUNCTION_BLOCK SMC_SegmentAnalyzer

This function block analyzes the different segments (acceleration constant velocity, deceleration) of a CNC path, independently of the interpolator function block. With every call, the SMC_SegmentAnalyzer outputs basic information about the current path segment and adds up the time that will be needed for its interpolation.

Restrictions:

The complete path must fit into the input path queue. The execution on the output path queue by the next function block (usually SMC_Interpolator ) may only begin, when SMC_SegmentAnalyzer has analyzed the queue completely.

InOut:

Scope	Name	Type	Initial	Comment
Input	bExecute	BOOL	FALSE	With a rising edge, the function block gets active
	poqDataIn	POINTER TO SMC_OUTQUEUE	0	Input path queue
	iVelMode	SMC_INT_VELMODE	TRAPEZOID	Velocity mode (same as SMC_Interpolator )
	dwIpoTime	DWORD	0	Cycle time of the interpolation task (same as SMC_Interpolator )
	bMFunctionsPreAcknowledged	BOOL	FALSE	If the input is set to TRUE, every M-function is acknowledged in advance. If the input is set to FALSE, M-functions cause a stop, but they are acknowledged immediately.
	dJerkMax	LREAL	0	The magnitude of the maximum allowed jerk (same as SMC_Interpolator ).
Output	bDone	BOOL	FALSE	This output will be set to TRUE as soon as the input data from poqDataIn has been processed completely. The function block will not perform any further actions until it gets reset.
	bBusy	BOOL	FALSE	TRUE while execution of function block is not finished
	bError	BOOL	FALSE	It signals that an error has occurred within the function block
	wErrorID	SMC_ERROR	SMC_NO_ERROR	Error identification: SMC_SA_QUEUE_NOT_IN_BUFFER SMC_SA_QUEUE_CHANGED_DURING_OP
	segCurrentSegment	SMC_SEGMENT		Description of the current segment
	dTime	LREAL		Total (summed) interpolation time over all segments output so far.
