Note
The network settings of the control should be saved.
They can be found under PLC:\NET\ ...
Move the cursor to the corresponding filed, press the soft keys AUX. FUNCTIONS and
PROTECT. A P is shown in the status column for "protected".
Note
After restoring the machine backup and subsequently booting the control, the following
problem can occur with older NC software versions:
In the original MP list the control requires additional parameters (e.g. as of index xxx.5).
Background:
In the OEM.SYS there is the entry AXISNUMBER.
This serves to specify the number of axes for which indices are to be created in the MP file
(e.g. indices xxx.0 to xxx.8 for 9 axes).
If a control boots without PLC data, the MP list is added to the hardware configuration (i.e.
on controls with 5 axes only up to parameter xxx.4).
The same is true if the PLC data of a control were lost and for new or exchange controls.
The number of axis indices exceeds the hardware configuration for example if the spindle
drives more than one axis (C-axis mode, etc.).
I.e., when booting the first time during data restoration the original MP list is truncated and
therefore no longer useful.
Solution:
1. Load MP_NAME.MP into the editor.
(as long as the original MP list is open for editing, it cannot be restored).
2. Load the entire backup on the control again.
3. Reboot the control.
