FUNCTION_BLOCK SMC_GCodeViewer
This function block can be used in combination with the SMC_NCDecoder. It gathers and stores the textual representation (G-code) of the particular SMC_GEOINFO objects and dumps those as an ARRAY OF STRING, which e.g. via a table can be displayed in a visualization. Via an entry, typically connected with the interpolator output iActObjectSourceNo, the module gets information on which line already has been processed and then deletes this line. So an visual display element for the current G-code can be created.
..note:: that the output of the function block does not exactly match
with the G-code stored in the editor or in the text file, because e.g. no blank lines or comments will be copied. Also, variables will already be replaced with their value.
The function block is called in the same task as SMC_NCDecoder.
It must get an sufficient buffer. The number of SMC_GCODEVIEWER_DATA objects at least must be as big as the sum of all SMC_GEOINFO objects which are located in the buffers of the SMC_NCDecoder module and the path-preprocessing modules.
