Online contour visualisation

Activation

Online contour visualisation is activated by transferring the program start option ON_LINE on the HLI to the controller at program start (see documentation on the HLI).

As opposed to rapid contour visualisation, the online contour visualisation mode executes the real processing of the NC program. The read-out values are filtered to obtain a high-performance data transfer.

Sample grid

Data reduction can be applied in this operating mode. Depending on the motion block used (straight/curved), the interpolation point grid can be specified for the interpolation either

by specifying a maximum interpolation point interval
or a maximum path error can be specified (see “Selection via HMI / ADS“).

This can be defined in the following parameters:

Parameter	Format:	Description	Index-Group	Index-Offset
mc_contour_visu_grid_w mc_contour_visu_grid_r	UNS32	Output grid for nominal contour visualisation for linear blocks (G00/G01) in [0.1 µm]	0x2010<c> c element [1; max. channel]	0x89, 0x8a
mc_contour_rel_curv_error_w	REAL64	Maximum relative path error in [0.1%] for nominal contour visualisation of circles or polynomials	0x2010<c> c element [1; max. channel]	0x8b
mc_contour_abs_curv_error_w	REAL64	Maximum absolute path error in [0.1 µm] for nominal contour visualisation of circles and polynomials	0x2010<c> c element [1; max. channel]	0x8c

Parameterisation

Parameterisation takes place analogously to Rapid Contour Visualisation (see “Parameters”.)
