2.9 Multi-function switch/button S1
The multi function switch/button is constructed as follows:
run (switch)
stop/reset
clear (button)
The button S1 is assigned with the following functions
Action
Function
Run/Stop
Program is started
Run/Stop
Program is stopped, all variables are reset (reset
warm)
Stop –> Clear and hold (> 3 s) until
ERROR-LED lights
After releasing the switch all retain variables are reset
(reset cold)
Stop –> Clear and hold (>10 s) until
ERROR and RUN-LED light
All variables and the boot project are cleared (reset
origin) after releasing the button.
Since a C6 permits several IEC programs simultaneously (applications) all applications are
started/stopped/cleared with Run/Stop/Clear. The switch operation can be limited by functions
of the library "KEB PLC".
2.10 File system
The file system consists of an internal built-in flash memory (drive C:) and an internal RAM
memory (drive B:). Access is possible via the programming system, KEB ftp or directly by the
IEC control program (library „SysFile“).
From firmware version 3.4.1.3 single files are protected on drives B: and C: by an access
level. The access level is depending on the adjusted password via parameter ud.01.
The actual level is saved when creating/copying a file. The actual access level must be greater
or equal to the file level to delete or rename a file.
When using KebFtp only the user read/write password can be used for compatibility reasons
and appears internally as file level 1. From KebFtp 1.5.0.0 the actual access level is displayed
when selecting a drive and the file level when selecting a file.
2.10.1 Internally Ram-Memory
Drive B: is a temporary memory which is deleted after power on.
• Access is possible only to files in the root directory.
• Long file names to 32 characters are possible.
2.10.2 Internal flash memory
This memory is accessed as drive C:. Any other files (boot
projects, projects,
documentation, downloadlists, prescriptions, etc.) can be stored and read here.
