Selecting a workpiece
For a complete backup of all data in a directory, the identifier
COMPLETE is used for saving.
The complete backup of all data from all directories (INITIAL over all
areas) is saved in the INI file _N_INITIAL_INI.
When you read in a file, the path entered when you saved the file is
used. The system tries to read the file into the directory from which it
was saved. If the path is missing, then files with file type SPF are
stored in /SPF.DIR, files with extension .INI in the active working
memory and all other files in /MPF.DIR. Files are immediately
effective after import.
Data can be activated/edited by loading files into the working
memory. The exact time of activation depends on the type of data
activated in the file.
/LIS/ Lists
For example, machine data can take effect (depending on type)
1. Immediately
2. on "RESET"
3. on "Cycle-Start"
4. on "Power ON" – when the control is switched on again.
A workpiece can be selected for machining in a channel.
see Section:
"Select a Program on the NC for Execution",
"Execute Program from Network Drive, Compact
Flash Card, Disk".
If a main program of the same name exists in the workpiece
directory, it is automatically selected for execution. If you choose
workpiece SHAFT.WPD, then the main program SHAFT.MPF is
automatically selected.
If an .INI file of the same name exists, it is executed immediately
(i.e. it is loaded into the working memory of the NC). Main programs
with other names must be selected explicitly.
If a control has several channels, programs can be selected for
processing and started from one part program for another channel.
