4.11 Setting the color depth in the tcu.ini file
Per default, the color depth of the SIEMENS PC system is set to 16-bit via the tcu.ini
configuration file and is reset to this value at every run-up.
To use a different color depth, you must adapt the setting in the tcu.ini file in the
[VNCServer] section.
Requirement
● Hidden directories are not shown
● A copy of the tcu.ini configuration file is stored in the user directory: C:\ProgramData
\Siemens\MotionControl\user\System\etc\tcu.ini
● The tcu.ini configuration file in the user directory is not write-protected
See: Directory structure and file conventions (Page 14)
Procedure
To adapt the color depth of the PC system, proceed as follows:
1. Open the tcu.ini configuration file in the C:\ProgramData\Siemens\MotionControl
\user\System\etc\ directory.
2. Enter the required value in the [VNCServer] section (below the #COLOR DEPTH comment):
– ColorDepth=0
The color depth is not changed during run-up, but rather the color depth used last is
retained. In this way, you can adapt the color depth in the Windows settings.
– ColorDepth=1 (default value)
The color depth is set to 16-bit during run-up.
– ColorDepth=2
The color depth is set to 32-bit during run-up.
3. Save and close the file.
