Hi PLKM.
You can try to use in combination with . There are a few things in CODESYS which are executed with the Idle event. Call and a few times before the login.
If that does not help we could have a problem in the noUI mode which we need to investigate.

import clr
clr.AddReference("System.Windows.Forms")
from System.Windows.Forms import Application
from System import EventArgs
Application.RaiseIdle(EventArgs.Empty)

What is your Use Case for using the noUI mode?

The RaiseIdle Method seems to help. I will do some more tests in the next days.

The noUI mode is for automated tests for our controllers, which are running in the background.

I already tried it with System.Delay(x) before the login, but the failure still exists.
If i pregenerate the code with the generate_code() method it seems to be better, but the failure is still available sporadically.

I use SP10 Patch 1 and there is no interaction with CODESYS at least 15 seconds before the login method.

I already tried it with System.Delay(x) before the login, but the failure still exists.

If i pregenerate the code with the generate_code() method it seems to be better, but the failure is still available sporadically.

For our controllers with more functionality (more time to compile and generate code) i have sporadic problems with the login function, which returns sometimes with an exception. It seems that there is a timing problem within the function:

It never happend with the GUI.</traceback></type>

Which version of CODESYS do you use? Is the project just loaded before the login?

Instead of repeating the login you can try to add a delay with before the login. For the start I would use 5000ms and reduce it step by step if it works.
