Hello,
I am a newbie with Structure Text and something happened during my testing.
I was doing a WHILE loop and my best guess is that I created an infinite loop and my raspberry is now messed up...
After downloading the program and RUN -> I got response that there is no connection.

I am not able to establish a connection between codesys (my computer) and raspberry via "gateway".
Ping is going through anyway and I can access PI with SSH.

So how can I stop the program, or can I just delete the program somehow...

/edit:
Just to add, before this everything worked always OK.
I tried to access the files now via FileZilla FTP, but can not connect. Don't know if this is related problem or not.

Thanks,

-Juha

Hi,

I would recommend to Login by ssh (use putty for this).
then execute:

sudo -s
rm /root/app*

(this removes the boot application)

then a restart of the plc is needed

sudo service codesyscontrol stop
sudo service codesyscontrol start

Thank you Edwin,

Tried the commands above, but "No such file"...

root@raspberrypi:/home/pi# rm /root/app
rm: cannot remove ‘/root/app’: No such file or directory

"app*" I need to replace with my application name or just type like that?

//EDIT: Okay, got it running when realize the application name was the default "Application.app" not my project name...

Another thing I realized now is that it is still not possible to connect from codesys to Pi by IP-address, but only with that "target name" = [0001.A067].
Beside that got it working again, THANK YOU!

BR,
Juha
