Serial no. of MCI board
Known: The serial no. of the MCI board complies with the serial number last stored on
the PCU.
Unknown: The serial no. of the MCI board does not comply with the serial number last
stored on the PCU.
Unknown: Provided that the SRAM of the MCI board is OK, the system does not request
(SW update) which SRAM (MCI or IMAGE) is to be used when it runs up for the first time
after performing a SW update. The SRAM of the MCI board is always used.
SRAM image or SRAM backup (hard disk) “OK”
Yes: The following criteria must be fulfilled:
1. NC and PLC software version of SRAM image or backup must comply
with the installed software version.
2. Windows NT must be shut down correctly (to do so, the POWER FAIL
mechanism of the SINUMERIK 840Di is also sufficient)
3. The checksum test using the SRAM image or backup must be successful.
4. The battery status at the time of saving of the SRAM image must be O.K.
Used user data
MCI: The battery-backed user data in the SRAM of the MCI board will be used.
IMAGE: The user data battery-backed in the SRAM image on the hard disk of the
PCU will be used.
BACKUP: The user data battery-backed in the SRAM backup on the hard disk of the
PCU will be used.
Start-up The user data of the NC will be deleted and default machine data
will be loaded.
