Creating a service system for the NCU

Purpose
In case servicing is needed, create a portable "Emergency Boot System" (EBS) on a USB
memory. Thus you can start the booting of the NCU from the service system in order to carry
out various service tasks, such as data backup or updates, in a service shell.
Two partitions are created on the service system:
● a Linux partition that is invisible under Windows.
● an FAT partition for DOS or Windows applications.
Scope of delivery
To create a service system on a USB storage medium with 512 MB storage capacity, the
following files are included on CD:
● an executable file installdisk.exe
● an image file linuxbase-512M.img for USB-FlashDrive with 512 MB
● an image file linuxbase-resize.img for USB-FlashDrive > 512 MB
● a file with the newest information siemensd.txt
Recommendation:
Preferably, the SIMATIC PC USB-FlashDrive with 512 MB storage capacity should be used.
Note
To create the service system, you need administrator rights.
All data already on the USB storage medium will be deleted.
The transfer is optimized for USB 2.0; therefore, the transmission to the USB storage
medium takes longer when using USB 1.1 than USB 2.0
Proceed as follows
To create a service system on a 512 MB USB storage medium:
1. Copy the service system onto a local hard disk of your programming device (PG) or PC.
2. Connect a 512MB USB storage medium to the USB interface of the PG/PC.
3. Determine in Windows Explorer which drive letter the USB storage medium was
assigned, e.g. H:
12
The FAT partition can be addressed using the path /data, and can be read and written to
under Linux and also from a Windows system.
