L_MC2P_CamRefFromStruct

This FB generates an MC_CAM_REF structure for the FB MC_CamIn online from the transmitted cam data (basic conditions, characteristics, or data points)

The instance of the FB

is an interface of MC_CAM_REF type

can directly be connected to an input of MC_CAM_REF type of another FB, e.g.

CamTable input of the FB MC_CamIn

CamTable1 input of the TM L_TT1P_FlexCamBase

Programming example:


      MC_CamIn1.CamTable:= L_MC2P_CamRefFromStruct1

sName STRING(50)	Name of cam
eCamType L_MC2P_CamType	Type of cam data: XYVA: Description via basic conditions lrX, lrY, lrYs, lrYss DataPointsNonEquiXYA: Description via data point table with lrX, lrY, lrYss DataPointsEquiYA: Description via equidistant data points with lrY, lrYss DataPointsNonEquiXY: Description via data point table with lrX, lrY DataPointsEquiY: Description via data point table with lrY
udiCamDataCount UDINT	Number of the transmitted profile elements
itfCamData L_MC2P_IMotionData	Cam data
eInterpolationQuality L_MC2P_InterpolationQuality	Interpolation type (optional for data point tables): Linear: Interpolation with first-order function (line)
lrXStartPos LREAL	X starting position of the curve
lrXEndPos LREAL	X end position of the curve

Outputs

Name Data type	Value/meaning
xDone BOOL	TRUE	Generated cam data is available.
xBusy BOOL	TRUE	Processing is running.
xError BOOL	TRUE	An error has occurred. For details see eErrorID .
eErrorID L_IE1P_Error	If xError = TRUE: Error number for the error that has occurred.
