2. Windows XP must have been shut down correctly (the POWER FAIL
mechanism of the SINUMERIK 840Di sl 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 the SRAM image
must be OK.
Used user data
MCI: The battery–backed user data in the SRAM of the MCI board are used.
IMAGE: The battery–backed user data in the SRAM image on the hard disk of the
PCU are used.
BACKUP: The battery–backed user data in the SRAM backup on the hard disk of the
PCU are used.
Commissioning: The user data of the NC are deleted and default machine data
loaded.
Before replacing the PCU backup battery, the SINUMERIK 840Di sl or Windows
XP must be shut down correctly.
For shutting down, use one of the following options:
S
Windows taskbar: Start > Shut Down
S
Interface signal: "PC shutdown", see Section 18.1.1, Page 18-499
If SRAM memory cells are inverted when changing the battery, this will be de-
tected during power–up. The SRAM image will then be written back to the
SRAM of the MCI board and the SINUMERIK 840Di sl is now immediately ready
for operation.
Responses
None.
Notice
If Windows XP is not correctly shut down before changing the backup battery,
an inversion of the SRAM memory cells during the battery change cannot
reliably be detected.
The SINUMERIK 840Di sl must then be recommissioned.
After the MCI board has been replaced, the subsequent procedure depends on
the previous history. The following cases are distinguished:
1. An up–to–date SRAM image exists
2. An up–to–date SRAM image does not exist.
