1 General Information on the SINUMERIK 840Di sl
S
Color depth
The default color depth setting is 65536 colors. Higher values can, in certain
circumstances, increase the CPU time used by Windows XP and occasion-
ally also by the real–time operating system.
If it is necessary to test the screen resolution or switch to a different resolution
and/or color depth, the NCK must be terminated first. Otherwise a malfunction
may occur in the real–time response.
Notice
Screen savers that modify the screen resolution when activated must not be
used in conjunction with SINUMERIK 840Di sl.
The NCK is integrated in Windows XP as a "SINUMERIK–NC" service.
This service must be started and stopped manually in the service dialog box.
Windows Start menu: Start > Programs > Administrative Tools > Services >
"SINUMERIK–NC"
Warning
The NCK must be stopped before testing/switching the screen resolution
and/or color depth on the PCU and started again explicitly after
testing/switching using the Windows XP service "SINUMERIK–NC".
Otherwise a malfunction may occur in the real–time response.
To offer high quality and wide functionality of the entire system,
SINUMERIK 840Di sl comes completely configured and ready to operate.
For this purpose, the system components used are subject to a certification
procedure with Siemens as the system manufacturer. This is to certify and
document compliance with real–time capability of the whole configuration.
If PC components (hardware or software) are modified or expanded by a third
party, compliance with product features cannot be guaranteed. These are the
sole responsibility of the OEMs or the user who has made the modifications.
The effect of the changes to the system software can be read on the user inter-
face of the "840Di Startup" or "HMI Advanced" commissioning tool (see Section
11.11.1, Page 11-406). It graphically displays whether the installed hardware or
software violates the real–time conditions.
