Post subject:  Licensed BBB No connection to device

Hi,

I use a licensed BBB. When i execute the Scan Network, Codesys can detect my BBB but, suddenly, when i try to LogIn, Codesys throws this error:

"No connection to device. Please Rescan your network!"

From now on, if i rescan my network, Codesys cannot find any device.

At the contrary i can login without any problems using PUTTY.

It's very annoying! I am not able to go on with my work!

Any help would be appreciated!

Thanks!

Hi,

first i would recommend to do a
cat /tmp/codesyscontrol.log
by your ssh connection.
This should show you where the problem is.

If the problem is caused by a bootproject which crash on startup of the application(usually this might be the problem)
you could delete it by:

rm /var/opt/codesys/PlcLogic/Application/Application.app

then a restart or the runtime

/etc/init.d/codesyscontrol stop
/etc/init.d/codesyscontrol start


BR
Edwin
