dXOffset: LREAL
Offset to the position of the X axis
X_Axis: AXIS_REF
X axis, position of the workpiece
Outputs (VAR_OUT)
bDone : BOOL
This variable is set to TRUE as soon as the input data from DataIn has been fully processed.
Thereafter the program organisation unit will not execute any more actions until a reset
has been performed. If the bExecute input is FALSE, bDone will also be reset to FALSE.
bError : BOOL
This value will be set to TRUE if an error occurs.
wErrorID: SMC_ ERROR (INT)
If applicable, this enum output will describe an error that occurred during interpolation.
Following an error, processing will be stopped until a reset is performed.
piSetPosition: SMC_POSINFO
Set_Position contains the set position calculated in accordance with the specifications
made. Set_Position is an SMC_POSINFO structure and not only contains the Cartesian
coordinates of the path position point to be approached, but also the position of the
additional axes.
iStatus: SMC_INT_STATUS (INT)
This enum variable shows the current state of the program organisation unit. Possible
states:
bWorking: BOOL
This output assumes the value TRUE once list processing has begun and before it has been
completed (IPO_ACCEL, IPO_CONSTANT, IPO_DECEL or IPO_WAIT). Otherwise Working is
FALSE.
iActObjectSourceNo: INT
The SourceLine_Nr value of the GEOINFO object in the DataIn queue that is currently being
traversed can be found here. If SMC_Interpolator is not (or no longer) working (Working =
FALSE), -1 appears here.
State Value Information
IPO_UNKNOWN 0 Internal state. State may not occur after a complete
SMC_Interpolator pass.
IPO_ACCEL 2 Program organisation unit is currently accelerating.
IPO_CONSTANT 3 Program organisation unit is currently moving at a constant velocity.
IPO_DECEL 4 Program organisation unit is currently decelerating.
IPO_FINISHED 5 Processing of the GEOINFO list is finished. Any other GEOINFO
objects that arrive in DataIn subsequently will not be processed.
