7.2 SMC_GCodeViewer
This POU can be used in combination with the SMC_NCDecoder. It collects and stores the
textual representation (G code) of the individual GeoInfo objects and outputs it again in
the form of an ARRAY OF STRING, which can be output by means of a table in the
visualisation, for example. Via the input, which is typically connected to the interpolator
output iActObjectSourceNo, the POU receives information about which row has already
been dealt with and deletes it. In this way, a display element of the current G code can be
created.
Please note that the output of this POU does not correspond to the G-code that is stored in
the editor or text file, as here for instance no blank lines or comments are accepted.
Variables that might be used are already replaced.
The POU is called in the task context of the SMC_NCDecoder programm organisation unit.
A buffer of sufficient size has to be transmitted to it. The number of the
SMC_GCodeViewer_DATA objects at least has to be as great as the sum of all
SMC_GeoInfo objects which are created in the buffers of the SMC_NCDecoder POUs and
the path preprocessing POUs.
