On one of the lathes with a Fagor 8050T / 8055T, the backup battery when dead.
I got backup of the following files that I guess is the files needed to get it back up running again:
PLC_ERR.PIT, PLC_MSG.PIT, PLC_PRG.PIT and 999996 to 999999.PIT.
I have managed to connect the PC to the lathe with WinDNC and been able to get almost all files over to the lathe.
One or two of the 999999_ files will not be copied since it has is write protected.

How shall I get the PLC files and 999999_ files to work on the lathe? Do I need to copy them to the eeprom or is the files already on the eeprom?

Why will not some files be copied since the write protection?

Thank for your help in advance.
