SMC_PreAcknowledgeMFunction (FB)

FUNCTION_BLOCK SMC_PreAcknowledgeMFunction

This function block serves to acknowledge an M-function even before the interpolator reaches it. If an M-function is acknowledged in advance, a stop at the M-function is avoided. The function block should be executed in the same task as the interpolator. It operates on the queue that is fed into SMC_CheckVelocities .

Note

To pre-acknowledge a G75 command, set input iM to -2.

InOut:

Scope	Name	Type	Initial	Comment
Input	bEnable	BOOL		TRUE: the function block is active
	iM	INT		Number of the M-function
	poqDataIn	POINTER TO SMC_OutQueue		Points on the SMC_OUTQUEUE structure object containing the SMC_GEOINFO objects of the interpolating path. This must be the queue that is also fed into SMC_CheckVelocities .
Output	bDone	BOOL		This variable will be set to TRUE as soon as the input data (poqDataIn) has been processed completely. Hereafter, the function block will not perform any further actions until a reset will be done. If input bExecute is FALSE, bDone will be reset to FALSE.
	bBusy	BOOL		TRUE while execution of function block is not finished
	bError	BOOL		Signals that an error has occurred within the function block
	wErrorID	SMC_ERROR	SMC_NO_ERROR	Error identification
