# Settings for generating debug data (debug.*)

Debugging NC programs on the controller requires the supply of certain additional information. For example, this includes the stored values or calculated results of the parameters and variables programmed in the NC blocks and of the expressions generated from them.

Systems that support debugging of NC programs can access this debug data and can display it accordingly on their user interfaces.
