SINUMERIK 840Di sl Manual (HBIsl) – 01/2007 Edition
Before the MCI board has been changed, Windows XP could not be shut down
correctly. An up–to–date SRAM image is thus provided.
During power–up, the MCI board is detected as a new one using the HW serial
number. The SRAM image will then be written back to the SRAM of the MCI
board. The SINUMERIK 840Di sl is thus ready again immediately.
Responses
A note will appear in a message box, which must be acknowledged with ”OK”:
SINUMERIK 840Di sl NCK/PLC
Note: User data loaded into MCI card.
Notice
1. If the MCI board is recognized as being faulty while the SINUMERIK
840Di sl is booting, the last SRAM image is retained when Windows XP is
shut down. After the MCI board has been changed, proceed as described
above.
2. If the MCI board is to be replaced as a result of a suspected or actual error
(suspected error, sporadic errors, etc.), the SINUMERIK 840Di sl NC and
PLC should be recommissioned, as possible data errors may otherwise be
imported from the SRAM image.
A fault occurred with the MCI board during operation of the SINUMERIK
840Di sl. Windows XP has possibly been shut down correctly, but no SRAM
image could be created.
After replacement, based on the hardware serial number the MCI board will be
identified as ”unknown”. Since no up–to–date SRAM image exists, the SRAM
backup is written back into the SRAM of the MCI board. The SINUMERIK
840Di sl is now immediately ”operational”.
The user data, or operating state of the SINUMERIK 840Di sl must be checked
to ascertain if operation can be continued. It might be necessary to recommis-
sion the SINUMERIK 840Di sl NC and PLC.
