SMC_NCDecoder
This function block is part of the CoDeSys SoftMotion library
"SM3_CNC.library". The function block SMC_NCDecoder is used to
convert a CNC program (Din 66025, G-Code), which has been created
within the CNC-Editor, into a list of SoftMotion-GEOINFO-structure
objects. In each cycle one line of the program will be decoded.

SMC_CheckVelocities
This function block is part of the CoDeSys SoftMotion library
"SM3_CNC.library". The module checks the track speed of the particular
path segments. If the OutQueue has not been created by the editor, but by
the IEC program (e.g. by SMC_NCDecoder), this module has to be called
straight before each call to the interpolator.
The main task of this function is to check the path for sharp bends and to
reduce the velocity to zero at these bends.

4. SMC_Interpolator

SMC_Interpolator
This function block is part of the CoDeSys SoftMotion library. The
SMC_Interpolator function block is used to convert a continuous path
described by SMC_GEOINFO-objects into discrete path position points
taking into account a defined velocity profile and time pattern. Afterwards,
these position points will typically be transformed by the IEC-program (e.g.
to drive-axis-positions) and sent to the drives.

If you want to move in y-direction
the drives A und B must be moved
in parallel; for a pure x-movement
they have to be contrary rotated.

SMC_Controlaxisbypos
This function block is part of the CoDeSys SoftMotion library. It can be
employed to write target positions to a drive structure and to test the
structure for jumps. It is mostly used in context with CNC and
SMC_Interpolator. For direct control of the axis’ set values, one of the
function blocks staring with SMC_Follow* should be used.

SMC_ReadNCFile
This function block is part of the 3S-Smart Software Solutions GmbH
CoDeSys SoftMotion library. It will read a NC-ASCII-file from the file
system of the controller, in order to make it available for the
SMC_NCDecoder. Thus at runtime a NC program can be read in and
realized.
