1.1 Overview of SINUMERIK 840Di sl
1.1.8

Deactivation

Windows XP
NC and PLC
1-30
To ensure safe operation of the SINUMERIK 840Di sl, Windows XP must be
shut down correctly before the PCU is switched off.
Note
Windows XP is shut down correctly as follows.
– Windows XP start bar: Start > Shutdown
– PLC interface signal: "PC shutdown", see Subsection 18.1.1, Page
18-499
Failure to shut down Windows XP correctly can damage the Windows XP instal-
lation and prevent the SINUMERIK 840Di sl from operating.
On correct shutdown of Windows XP the following occurs:
– The SINUMERIK 840Di sl components NC and PLC are terminated
correctly
– The NC and PLC user data in the SRAM of the MCI board and on the
hard disk of the PCU are backed up.
If the PCU is switched off without first correctly shutting down Windows XP, the
SINUMERIK 840Di sl's POWER FAIL functionality:
– ends the NC and PLC correctly;
– saves the NC and PLC user data in the SRAM of the MCI board.
The NC and PLC user data cannot be backed up on the hard disk of the PCU.
Notice
If you switch off the PCU without first having correctly shut down Windows XP,
please observe the following:
1. Supply voltage
A supply voltage of the PCU of at least 24 V is required to ensure
consistency of the NC and PLC user data.

Chapter: PCU 50.3
2. UPS system
The internal power backup time after switch–off is not long enough for
Windows NT to shut down correctly. To remedy this, we recommend using
an uninterruptible power system (see Subsection 1.1.9, Page 1-31).
3. Replacing the MCI board or PCU battery
When Windows XP is shut down correctly, the current NCK and PLC user
data are saved to the SRAM of the MCI board and to the PCU's hard disk.
If the MCI board or the PCU battery is replaced after the abnormal
shutdown of Windows XP, this will result in loss of the battery–backed user
data on the SRAM of the MCI board. How to proceed further: see
Subsection 5.3.3, Page 5-112.
