9 Software structure

9.1 Software structure
The software structure shows the data flow between the DNC user interface, the
servers and the machine.
All transfer functions are handled via the machine servers. Standard or user-
specific code conversions can also be carried out, if necessary. You can call up
either the DNC code conversion server or your own code conversion server. You
could set up your own code conversion server in such a way that it then calls up
the DNC code conversion server. Depending on the project, an external dialog
interpreter can be used for the dialog function. In this case, the data flows to the
machine server via the dialog interpreter, where the code is converted, and then to
the machine.
