SMC_TranslateQueue3D (FB)

FUNCTION_BLOCK SMC_TranslateQueue3D

This function will translate the path stored in poqDataIn to the vector given by vec, which is of structure type SMC_VECTOR3D .

The input variable poqDataIn is a pointer to the structurer SMC_OUTQUEUE, which describes the path to get rotated. The initialization value FALSE of input variable bEnable will bar the rotation of the path. As soon as bEnable is set to TRUE all SMC_GEOINFO objects found in poqDataIn will be processed. When bEnable is reset to FALSE, the module will not execute any further modifications.

The initialization of input variable bReset with FALSE effects, that the SMC_GEOINFO objects currently found in poqDataIn will not get rotated, but only those that will be added.

As, during the processing, a sudden change of the characteristic parameter vec of the translation might cause the path to be broken, modifications to the corresponding input will not be taken into account, until SMC_OUTQUEUE will be empty at poqDataIn or until a Reset (bReset) will be done.

InOut:

Scope	Name	Type	Initial	Comment
Input	bExecute	BOOL	FALSE	While TRUE, the function block is active
	bAppend	BOOL	FALSE	If FALSE at a rising edge of bExecute, the output queue poqDataOut is emptied.
	poqDataIn	POINTER TO SMC_OUTQUEUE	NULL	Pointer on a sufficiently large, free data area (buffer) that is allocated in the IEC application.
	vec	SMC_VECTOR3D
	nSizeOutQueue	UDINT	0	This variable contains the size of the data buffer, the list of SMC_GEOINFO structure objects will be written to. This buffer must be at least five times as big as a SMC_GEOINFO structure itself. Otherwise, SMC_NCDecoder will not execute any actions at all. Its size may be predefined, but may be modified later only during a reset. It is recommended to create the buffer as described by the example below. ExampleBuf: Array of SMC_GeoInfo The appropriate buffer size will then be retrieved by use of the operator sizeof(ExampleBuf).
	pbyBufferOutQueue	POINTER TO ARRAY [0..0] OF SMC_GEOINFO	NULL	Size of the buffer in byte
Output	bDone	BOOL	FALSE	This variable will be set to TRUE as soon as the input data of poqDataIn has been processed completely. Thereafter the module will not perform any further actions until it will be reset. If input bExecute is FALSE, bDone will be reset to FALSE.
	bBusy	BOOL	FALSE	TRUE, while execution of function block is not finished
	bError	BOOL	FALSE	Signals, that an error has occurred within the function block
	wErrorID	SMC_ERROR	SMC_NO_ERROR	Error identification
	poqDataOut	POINTER TO SMC_OUTQUEUE	NULL	Pointer to resulting SMC_OUTQUEUE
