Commissioning a System

1.1

Delivery condition of the system

Scope
This document is valid for all systems that are supplied with Linux as operating system on
the CF card, such as all NCUs of the type NCU 7x0, PCU 321, etc.
Directories on the CF card
When the system is in operation, the following directories are available on the CF card (this
is a selection and not a complete list):
Directory
/siemens
/addon
/oem
/user
/system
/user/system/etc
/user/common/tcu
/var/log/messages
Files in the directory under /user always have priority over files with the same name in the
directory /oem → /addon → /siemens.
CAUTION
Suitable editors for Linux
In most Linux system files, lines may only be ended with LF, and not with CRLF as in
Windows. Bear this in mind when selecting an editor. The editor of the internal HMI under
"Start-up" is suitable.
In the Linux operating system, the UNIX Editor vi is available.
Note that the Linux operating system is case-sensitive.
