108 Step-by-Step Guide to your own Linux Application
Running the new Program
WAGO-I/O-SYSTEM 750
Linux Fieldbus Coupler
The Konqueror is another FTP client. Start the program and change to the
/targetfs root directory. Start another instance of the program instance and
change to the target directory of the Linux fieldbus coupler using ftp://<IP
address>/bin. Now you can drag and drop files between the directories.
5.8 Running the new Program
The new program can be executed on the Linux coupler via the console, e.g.
via the terminal (see chapter 4.3).
> chmod +x /bin/newProg
In any directory you can run the command
> newProg
HelloWorld!
5.9 Automatic start of new Programs (inittab/startwago)
During the startup of the operating system, Linux starts the processes that can
be found in the inittab file during boot-up: in our system, inittab looks as
follows:
::sysinit:/etc/rc
::sysinit:/etc/startwago
::respawn:/etc/getty -L ttyS0 38400
In this file, the startwago file with the attribute sysinit is run, among others.
This means, the startwago script is started once during the system start-up.
The getty program which also supports the serial interface is started as a
respawn process. This process is thus restarted automatically if it is
terminated. The attributes are:
sysinit
Is started once during system start-up.
bootwait
Is started once after all sysinit processes.
respawn
Is restarted automatically if the process was terminated.
Please refer to the initab manpage for more attributes.
