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
