Note
During the internal data backup, a memory copy of the memory backed up for a limited time is made and stored in
the permanent memory. Selective data backup (e.g. only the machine data and not the part programs) is not pos-
sible.
Saving data internally:
Use the ETC key to extend the menu in the Diagnosis/Start-up menu and press the
Save data softkey.
Loading data from an internal data backup:
Boot the control system using the start-up switch, position 3
If the data in the backed-up memory area are lost, on POWER ON the data saved in
the permanent memory area are automatically reloaded into the memory.
Note
The note "4062 Data backup copy has been loaded" appears.
Saving data externally
In addition to the internal data backup, the user data of the control system can and must also
be saved internally.
External data saving requires a PC/PG (programming device) with V24 interface and the
WinPCIN tool (included in the tool box).
External data saving should be performed whenever substantial changes in the data have
been made, as well as always at the end of start-up.
External data backup variants:
1. The data record is read out completely, creating the series start–up file. This is intended
for series start–up or to restore the control system status after replacing hardware compo-
nents or after data loss.
2. Files are read in or read out by areas. The following user data can be selected as indivi-
dual files:
Data
– Machine data
– Setting data
– Tool data
– R parameters
– Zero offset
– Compensation data (LEC)
