C0040401 error: no connection with controller

Sorry, guys, I am new to ABB robotstudio.
I want to use ABB IRB140 for welding. Currently I try to study RAPID programming.
I have input all my models, including robot, tool and work piece, and then planned a short path, in the simulate module I synchronized the path to the VC already, then I can simulate the robot path, no problem.
And now, I want to test the RAPID programming. In the controller and RAPID module, I can see the generated RAPID code, and then if I want to change the RAPID code, and start execution of the RAPID code, there is C0040401 error: no connection with controller. However, even if I do not change any RAPID code, the same error.

How to fix this problem? Is there any examples to start RAPID programming?

Thanks
Best regards
