6.4.6 Defining and activating user data (GUD, LUD) via RS-232 C
The following error messages appear in the dialog line:
"Error occurred during activation of file"
Output of NC alarms:
Once the maximum number of files on the NC has been reached, no
more backup files can be created. The following acknowledgeable NC
alarms appear: "Too many part programs in the NC memory"
"NC memory full"
The same applies when activating macro files (.MAC).
1. Save _N_INITIAL_INI block via RS-232 C.
Create a definition file for user data in the Program operating area:
Predefined file names are used:
_N_GUD1_DEF (global Siemens data),
_N_GUD2_DEF (global machine manufacturer data),
_N_GUD3_DEF (global user data),
_N_GUD4_DEF to _N_GUD9_DEF (additional global data,
e.g. grinding cycles, etc.)
Files with these names can contain definitions of GUD variables.
The same rules apply to these as to LUD variable definitions.
2. Load definition file to main memory via RS-232 C.
The control system always creates a directory named
_N_DEF_DIR. This name is entered in the header of the GUD
definition file as a path:
DEF NCK REAL NCKVAR
DEF CHAN INT CHANVAR
3. Load "Init files": User definition files are active.
