3.4  Pre-configurations 
3.4.1  General information 
After the calibration of the Touch Screen the pre-configurations are available. 
Notes on all pre-configuration 
The following information applies to all pre-configurations. 
 
NOTICE 
 
The Windows Firewall is enabled. All necessary SIMATIC protocols are registered as 
exceptions. You can use the CP 5611 or the Industrial Ethernet interface to download 
STEP 7 projects. 
 
You do not have to perform any additional configuration in the PC Station or in WinLC 
Properties. WinLC RTX submodules communicate in the RTX environment, and the  
PC Station components communicate in the Windows Embedded environment.  
 
NOTICE 
 
If for any reason you need to reconfigure your PC Station with the Station Configuration 
Editor, you must choose "IE General" for the Industrial Ethernet interface. 
 
You can connect other devices such as a mouse, keyboard, or storage device to the 
hardware platform through the USB ports. You can connect a monitor through the  
DVI-I interface. A monitor, USB mouse, and USB keyboard are necessary only for user 
interaction with the controller or with other software. To use the restore DVD, you need a  
‘USB DVD-ROM drive. You do not need a storage device for WinLC RTX operation except 
when restoring your installation.  
The hardware platform contains NVRAM. You can use this non-volatile RAM for retentive 
data storage. WinAC RTX is pre-configured to store up to 128 Kbytes of retentive data in this 
integrated, battery-buffered NVRAM of the hardware platform. 
If the retentive data is greater than 128 Kbytes, you must select "File storage" for WinAC 
data storage. The hardware platform uses a CompactFlash card for file storage. In order to 
save retentive data in a power loss situation, protect your system with an Uninterruptible 
Power Supply (UPS). 
Typically, you use the Enhanced Write Filter (EWF) to protect the C:\ drive of the 
CompactFlash card; however, you must take care to manage the EWF if you use the  
C:\ drive for any file storage. Typically, you leave the EWF disabled for the D:\ drive.  
File storage on the D:\ drive thus requires no special handling.  
Refer to the WinAC RTX documentation for information on configuring WinAC data storage.  
In addition to this documentation, you can find technical specifications and other information 
in the SIMATIC Embedded Bundles product documentation. Refer to the accompanying 
WinAC RTX documentation for a complete description of WinAC RTX and how to use it for 
PC-based Automation solutions. The 
Introduction (Page 5) of this documentation lists other 
manual
s that may be useful.
